Accessibility Issues In The Angular JS Application

Angular JS is a JavaScript-based open-source front-end web framework introduced by Google for developing single-page applications. While learning to develop single-page Angular JS Application at Angular JS classes in Pune, focused elements are the software architecture, performance, security, testability, and maintainability of the software but not the accessibility. Besides taking it for granted the Google experts are developing high-quality Angular Components and the Angular CDK (Component Development Kit), for several tools to improve accessibility.

 Angular JS training institute in Pune

How Angular and Angular CDK assist developers in solving accessibility issues?


In the Angular JS accessibility starts from the UI design phase where color palates are decided to meet the accessibility standards. With the use of right typography, simple animations and user interaction can reduce the error intensity in reading and understanding the application. The angular CDK provides a mixin CDK-high-contrast to style high contrast mode users. At the Angular JS course in Pune, users will learn a variety of assistive technologies to interact with web-based software applications.

 Accessibility attributes  

ARIA attribute is involved to provide web-accessible semantic & the attribute binding template syntax that control the values of accessibility-related attributes.


content_copy<!– Use attr. when binding to an ARIA attribute –>

<button [attr.aria-label]=”myActionLabel”>…</button>

The syntax is used for attribute bindings. Static ARIA attributes require no extra syntax.

content_copy<!– Static ARIA attributes require no extra syntax –>

<button aria-label=”Save document”>…</button>


Angular UI components

The enrolled candidate will come to know about the Angular material library at Angular JS classes in Pune The suite of reusable UI components used with the native HTML elements with the standard interaction patterns that are important to accessibility. Live Announcement is one of the most important features provided by angular CDK in the applications for the visually impaired users on various social places.


For example:

LiveAnnouncer is used to announce messages as a standard interaction pattern for screen-reader users using an aria-live region.

For example, create a component that uses an attribute selector with a native <button> element. That applies to <button> and <a>, but can be used with many other types of element.

Example: MatButton, MatTabNav, MatTable.


Using containers for native elements

The appropriate native element requires a container element. For example, the native <input> element cannot have children, so custom text entry components need to wrap an <input> with additional elements. This makes it impossible for users of the component to set arbitrary properties and attributes to the input element by creating a container component that uses content projection to include the native control in the component’s API.


Example – MatFormField


Use of Semantic HTML

With the help of native elements, the proper semantics accessibility issues can be solved to boost-up the SEO of the application. Here semantic tags like nav, aside, main, section, fieldset, header, footer, etc. come in use instead of just using div and span.

Use the correct order for headings (h1-h6).      

  • Use alt attribute on img element.
  • Use alt attribute on img element.
  • Use button’s for clickables.
  • Avoid positive tabindex .
  • Add captions for video and audio.


Accessibility for interactions

Keyboard navigation is specially designed for motor disabilities and will help users navigate websites using just a keyboard. Angular CDK provides ListKeyManager for keyboard interaction using components like menus, dropdowns, selects, list boxes, etc.


Codelyzer and accessibility

In all the Angular CLI projects Codelyzer is used to detect a few common accessibility issues in Angular templates. 



Accessibility is a must for all web applications and it should be considered in the project development lifecycle. The Angular JS training institute in Pune will make the tools available to create Accessible Components, for developers to utilize them and create accessible Angular applications.


At LotusITHub’s Angular JS classes in Pune, aspirants can learn to build the application using the trending technologies and can work on all upgraded versions. The training sessions and live project demo will help the candidates to get the live experience before entering into the actual industry. We have our branches at all the vertices of Pune, you can visit us at Karve Nagar, Warje, Narhe, Dhayari, and Kothrud. Click on the for a brief introduction and visit us to book your seat now.

Core Java & Serialization Mechanism!

Java is the globally used object-oriented programming language and OOPs concept is the building block of JAVA with the four basic pillars i.e., Abstraction, Encapsulation, Inheritance, and Polymorphism. Java Classes in Pune will enable you to OOPs along with the Java control statements that include for, do, do-while, if-else, Switch case, continue and break statements etc.

In order to handle the collection of objects, JAVA provides the collection APIs with inbuilt classes and interfaces to handle the collection of objects. In the Java training in Pune, the experts will make you aware of the multithreading concept, to perform two or more task concurrently. In JAVA 5 there is java.util.concurrency package is given for developing the multithreaded application.

Serialization is one of the most important concepts frequently asked in the interview. We will discuss in detail about the mechanism called serialization and aspirant can take practical tutorials with the handy assignments on the same at Java classes in Pune.

As per the standard definition, “Serialization is a mechanism of converting a state of an object into a byte stream.” The mechanism is used to persist the Java object in a form of a sequence of bytes that includes object’s data and the data stored in the object. In the core Java, there is also a concept of deserialization which is the reverse process of serialization where the byte stream is used to recreate the actual Java object in memory. The serialized object can also be deserialized using the object’s type and other information to retrieve the original object.

During Java certification in Pune, the student will learn from the scratch where experts will guide them to understand the Classes ObjectInputStream and ObjectOutputStream streams for serializing and deserializing the object.

The commonly used serializing method from the ObjectInputStream is:


private void writeObject(ObjectOutputStream os) throws IOException




Similarly following is also one of the methods used in Java Serialization

private void readObject(ObjectInputStream is) throws IOException, ClassNotFoundException




The Need of Java Serialization

When the user needs to send or receive the data in the form of objects over the network or to store in a file then, serialization is used. Serialization is basically the translation of java objects values which are sent over the network or to save it. The entire serialization process in Java works independently in JVM where an object can be serialized on one platform and deserialized on an entirely different platform. When you serialize any object and if it contains any other object reference then Java serialization serialize that object’s entire object graph, this you can learn at Java course in Pune. It follows the inheritance concept which implies if superclass is Serializable then its subclasses are automatically Serializable and all values of the instance variables inherited from superclass will call the constructor of Non-Serializable Super class during the deserialization process.

At LotusITHub Java coaching classes in Pune, we have different industry experts who conduct the classes and guide the aspirant for the betterment of their future. Whether you are fresher or experience, you can visit our institute to learn from scratch. LotuITHub has branches across the breadth of the Pune, you can visit our Java classes at Karve Nagar, Kothrud, Warje, Narhe, and Dhayari for demo session at any time.

The training includes coaching with several activities, assignments, and scenarios that are practical experience in addressing predictive modelling problems. 

LotuITHub’s Python course will cover both basic and advanced concepts of Python that starts from Python scripts, sequence, file operations and more which uses libraries like pandas, NumPy, matplotlib, scikit, and master.

The objective of Python coaching classes

 Python is considered as a “Next Big Thing” for the professionals in the data analytics domain. It runs on Windows, Linux/Unix, Mac OS & cuts development time in half with its simple to read syntax and easy compilation feature. 

  • Programmatically download & analyze data with visualization
  • Python deals with the ordinal, categorical, and encoding techniques for different types of data
  • Python functions to facilitate code reuse with the core Python scripting elements such as variables and flow control structures.
  • Real-time data processing with tools & techniques for predictive modelling in order to gain expertise to handle business in future.

 Why Python?

Python is one of the most popular languages and easier to code & understand. It works as a bridge between businesses and developers to bring a program in a market as compared to other languages such as C#, Java, etc. At Python classes in Pune, you will understand how all types of application can build on Python starting from analytical to UI. Python applications are quicker to implement as there is no need to declare variable types.

How does Python work?

 Following are the key interpreters that translate the high-level Python language to low-level machine language.


Variables can be object types and scope which can be used to hold user inputs, local states, etc. Variables have defined names with which it is referred into the code. 

 Python supports the following standard data types viz; numbers, strings, sets, lists, tuples and dictionaries.

 Assign the value to the variable

Declare & assign value to a variable which is known as binding in Python

 Assignment sets a value to a variable:

myFirstVariable = 1

mySecondVariable = 2

myFirstVariable = “Hello You”


Data types are dynamically typed in python.


It supports Integers, decimals, floats are supported.

value = 1 #integer

value = 1.2 #float with a floating point



It is a sequence of letters enclosed in quotation marks and once they are created, cannot be changed.


a = ‘me’

a[1]=’y’ It will show Error



It allows to perform computation on variables as Python supports *, /, +, -, and floor division 

1//3 #returns 0

1/3 #returns 0.333

Following are the Modulus operators

  • String Operations
  • Casting
  • Set Operations
  • Ternary Operator



There two types of comments, single line comment & multiline comment


Single-Line Comments

#this is a single line comment


Multiple Line Comments

One can use:

“`this is a multi





Boolean operations can be performed with Expressions

  • Equality: ==
  • Not Equal: !=
  • Greater: >
  • Less: <
  • Greater Or Equal >=
  • Less Or Equal <=



Conversion of the object into string & using it into a file is known as pickling & the reverse of it is called as unpickling.




Executable sequence statements from the code are known as functions, moreover, repeatable code creates a reusable function.



A component that groups a similar functionality of python solution and provides the concept to share data and services called modules. Modules reduce the variable name clashes and encourage re-usability.



A directory of modules is called a package in the python large number of functionalities are grouped into the module files to create a package to distribute and manage modules.




The lotusITHub’s Python course includes the basic and step-by-step thorough understanding of the language. However, Python programming certification course enables you to learn data science concepts from scratch.

Angular JS – Most Popular JavaScript Framework

Angular is mostly used for building the web, desktop, and mobile applications that involve Typescript, a subset of JavaScript. Angular is one of the most popular JavaScript frameworks used in building web applications. Angular has three most known versions viz; Angular 1 (known as Angular JS), Angular 2, and Angular 4.

Angular JS – Most Popular JavaScript Framework

How all the version of Angular works?

At Angular classes in Pune, the candidates can come to know about the work process of the Angular and how each version works. Initially, Angular 1 was introduced followed by Angular 2 with some added features. Later by skipping version 3, the team has introduced the Angular 4 where Angular 2 code can be compiled easily. Angular JS and Angular 2 are quite different from each other whereas Angular 2 and Angular 4 share similar properties. Google has scheduled to release an upgraded version of twice a year however, Angular 4 is widely used and most popular among the developers. Angular 2 and above versions are backwards compatible.


Advantages of Using Angular JS

Angular JS coaching classes in Pune are famous for their practical tutorial where students can learn the practical and industrial advantages of using Angular JS. Single Page Application (SPA) loads the single HTML page and the page is uploaded dynamically. SPAs communicate with the back-end servers without refreshing the full web page. 

  • Two-way data binding

The two-way data binding in Angular JS used for automatic retrievals from (and updates to) the data store. In the Angular JS Institute in Pune, the student will also learn to update UI immediately when the datastore gets updated.

  • Modularity

In the Angular the modularity is organized in the form of “buckets”, and each bucket is known as “Module”. The module consists of related components, directives, pipes, and services that can be grouped to create an application. Module kept code organized and division of labour can be done properly while maintaining the code consistency.

  • Reduce coding

Angular supports MVC (Model View Controller) architecture where the developer can just split the code to make it fit into the MVC structure.

  • Declarative User Interface

Angular uses HTML for defining the user interface because HTML is intuitive, declarative, and less complex than JavaScript. 

  • Easy Integration

Integration of third-party features is easy with Angular as it has several pre-built frameworks like Ionic, Telerik’s Kendo UI, Wijmo, etc.

  • Cross-Platform

Angular Classes in Pune will make you learn how to design & develop web applications, native mobile applications, and desktop applications for Mac, Windows, Linux, etc. which is more useful in the software industry. 

Industrial Importance of Angular

Several large and popular websites are built on Angular. Some of them are as are The Guardian, PayPal, Netflix, YouTube for PS3, Lego, Freelancer, and more which make it one of the demanding platforms in the market. There are huge job opportunities are available in the various industrial sector for the skilled Angular JS developers which is the most important thing for the aspirants.

Learn OOPs & All Java Concept At LotuITHub?

In the interview, the usual question you face is regarding “Object-Oriented Programming” (OOP) which is associated with concepts like class, object, inheritance, encapsulation, abstraction, polymorphism, etc.

Learn OOPs & All Java Concept At LotuITHub

Java is one of the sought-after languages for beginners and professionals also. But the heck is for what classes, objects and methods are used? Why do we need inheritance and polymorphism? and more. At Java classes in Pune, an aspirant can learn everything about the OOPs, in detail.

  • Inheritance

In the Inheritance class properties of one class can be inherited by the other where reuse of code is possible to establish relationships between different classes. As we know in the biological system due to DNA child inherits some of the parent properties. Similarly, here “Child Class” (Subclass or derived class) inherits the properties from the “Parent Class” (Super or base class), inheritance is further classified into four types:

Let’s understand the concept with examples, where, Class A is your parent class and Class B is your child class

  1.       Single Inheritance


Class A {—}

Class B extends A {—}

  1.       Multilevel Inheritance

Please find the example below, where, A is the parent class for B and class B is the parent class for C.


Class A {—}

Class B extends A {—}

Class C extends B {—}

  1.       Hierarchical Inheritance

Please find the example below, where, Class B and C are the child classes that are inheriting from the parent class i.e Class A.

Class A {—}

Class B extends A {—}

Class C extends A {—}

  1.       Hybrid Inheritance

Class A and B extends class C → Hierarchical inheritance

Class D extends class A → Single inheritance

class C {

   public void disp() {



class A extends C{

   public void disp(){



class B extends C{

   public void disp(){



class D extends A{

   public void disp(){



   public static void main(String args[]){

D obj = new D();



  • Encapsulation

We can achieve encapsulation in Java by:

  1. Variable of the class are private.
  2. Public setter and getter methods are defined to modify and view the variable’s values.


public class Employee {

 private String name;

 public String getName() {

 return name;


 public void setName(String name) { = name;


 public static void main(String[] args) {



  • Abstraction

At Java coaching classes in Pune, an aspirant will learn the abstraction concept of Java programming in two ways:

  1.       Abstract Class

For the abstraction, you need to inherit the class from another class

The syntax of an abstract class:

Abstract class Mobile {   // abstract class mobile

Abstract void run();      // abstract method


  1.       Interface

In the abstraction class, an interface is a group of related methods with empty bodies.


public interface ParentCar {

public void changeGear( int newValue);

public void speedUp(int increment);

public void applyBrakes(int decrement);


  • Polymorphism

Java training institutes in Pune is the best place to understand the keen concepts of Java programming with real-life examples. Polymorphism defines one interface or method with multiple implementations.

Polymorphism in Java is of two types:

  1.       Runtime polymorphism


public Class BowlerClass{

void bowlingMethod(){

System.out.println(” bowler “);


public Class FastPacer{

void bowlingMethod(){

System.out.println(” fast bowler “);


Public static void main(String[] args){

FastPacer obj= new FastPacer();



  1.       Compile time polymorphism


class Adder {

Static int add(int a, int b){

return a+b;


static double add( double a, double b){

return a+b;


public static void main(String args[]){




This will help the aspirant to get an overview of the Object-Oriented programming concept of Java.

Comparisons between Java and Python

Difference between Java and Python:

Following are the major difference between java and python

Comparisons between Java and Python Java Python
1 Java is object-oriented programming language. Functional programming features are introduced into java 8.0 through lambda expressions. Python blends functional programming with object-oriented programming features. Lambdas are already available in python.
2 Java programs are verbose. It means they contain more number of lines. Python programs are concise and compact. A big program can be written using very less number of lines.
3 It is compulsory to declare the data types  Type Declaration is not required in python
4 Java language type discipline is static and weak. Python type discipline is dynamic and strong.
5 Java has do… while, while, for each loops. Python has while and for loops.
6 Java has switch statement. Python does not have switch statement.
7 The variable in the loop does not increment automatically .but in for each loop, it will increment automatically. The variable in the loop increments automatically.
8 Memory allocation and deallocation is done automatically by JVM (java virtual Machine). Memory allocation and deallocation is done automatically by PVM (Python virtual Machine).
9 Java a supports single and multi-dimensional arrays. Python support only single dimensional arrays. to work with multidimensional arrays, we should use third party application like numpy.
10 The array index should be a positive integer. Array index can be positive or negative integer number. Negative index represents a location from the end of the array.
