AngularJs

AngularJS extends HTML with ng-directives.

The ng-app directive defines an AngularJS application.

The ng-model directive binds the value of HTML controls (input, select, textarea) to application data.

The ng-bind directive binds application data to the HTML view.

AngularJS starts automatically when the web page has loaded.

The ng-app directive tells AngularJS that the <div> element is the "owner" of an AngularJS application.

The ng-model directive binds the value of the input field to the application variable name.

The ng-bind directive binds the innerHTML of the <p> element to the application variable name.

The ng-init directive initializes AngularJS application variables.

AngularJS expressions are written inside double braces: {{ expression }}.

AngularJS directives are extended HTML attributes with the prefix ng-.

The ng-app directive initializes an AngularJS application.

The ng-init directive initializes application data.

The ng-model directive binds the value of HTML controls (input, select, textarea) to application data.

This keyword

This is a reference variable that refers to the current object.

Usage of java this keyword

Here is given the 6 usage of java this keyword.

this can be used to refer current class instance variable.
this can be used to invoke current class method (implicitly)
this() can be used to invoke current class constructor.
this can be passed as an argument in the method call.
this can be passed as argument in the constructor call.
this can be used to return the current class instance from the method.

this() : to invoke current class constructor

The this() constructor call can be used to invoke the current class constructor. It is used to reuse the constructor. In other words, it is used for constructor chaining.

super keyword in java

The super keyword in java is a reference variable which is used to refer immediate parent class object.

Whenever you create the instance of subclass, an instance of parent class is created implicitly which is referred by super reference variable.

Usage of java super Keyword

super can be used to refer immediate parent class instance variable.
super can be used to invoke immediate parent class method.
super() can be used to invoke immediate parent class constructor.

The final keyword in java is used to restrict the user. The java final keyword can be used in many context. Final can be:

variable
method

class

Java final variable

If you make any variable as final, you cannot change the value of final variable(It will be constant).

Java final method

If you make any method as final, you cannot override it.

3) Java final class

If you make any class as final, you cannot extend it.

Is final method inherited?

Ans) Yes, final method is inherited but you cannot override it.

Can we declare a constructor final?

No, because constructor is never inherited.

featares of python

3. Huge nume of laibraries

Python is an object-oriented,
high level language, interpreted,
dynamic and multipurpose programming language.

Python is derived from many other languages,
including ABC, Modula-3,
C, C++, Algol-68, SmallTalk, and
Unix shell and other scripting languages.

Abstract and Interface

Abstract

A class that is declared with abstract keyword, is known as abstract class in java. It can have abstract and non-abstract methods (method with body).

Abstraction is a process of hiding the implementation details and showing only functionality to the user.

A class that is declared as abstract is known as abstract class. It needs to be extended and its method implemented. It cannot be instantiated.

abstract class

abstract class A{}

abstract method

A method that is declared as abstract and does not have implementation is known as abstract method.

Example abstract method

abstract void printStatus();//no body and abstract

An interface in java is a blueprint of a class. It has static constants and abstract methods.

Interface

The interface in java is a mechanism to achieve abstraction. There can be only abstract methods in the java interface not method body. It is used to achieve abstraction and multiple inheritance in Java.

Java Interface also represents IS-A relationship.

It cannot be instantiated just like abstract class.

Why use Java interface?

There are mainly three reasons to use interface. They are given below.

It is used to achieve abstraction.

By interface, we can support the functionality of multiple inheritance.

It can be used to achieve loose coupling.

Why multiple inheritance is not supported in java?

To reduce the complexity and simplify the language, multiple inheritance is not supported in java.

Consider a scenario where A, B and C are three classes. The C class inherits A and B classes. If A and B classes have same method and you call it from child class object, there will be ambiguity to call method of A or B class.

Since compile time errors are better than runtime errors, java renders compile time error if you inherit 2 classes. So whether you have same method or different, there will be compile time error now.

interface

abstract method

package javaapplication19;

abstract class animal{

abstract void eat();

abstract void run();

public void body()

{

System.err.println("two eye and two ear");

}

class lion extends animal{

public void display(){

System.out.println("king");

}

@Override

void eat() {

System.err.println("Meat");

}

@Override

void run() {

System.err.println("fast");

}

class cow extends animal{

public void display(){

System.out.println("mother");

}

@Override

void eat() {

System.err.println("grass");

}

@Override

void run() {

System.err.println("slow");

}

public class JavaApplication19 {

public static void main(String[] args) {

lion obj = new lion();

obj.body();

obj.eat();

obj.display();

obj.run();

}
