In this lecture we will learn:
- Object creation in Java
- Anonymous objects in Java
- Difference between Simple objects and Anonymous objects
#1
In JVM, we have both stack memory and heap memory.
- Object is created in the heap memory that contains variable and methods, it also have some address.
- A obj=new A();
obj.show();
here, A is the classname.
obj refers to the address say 101
show() is a method that is called using reference variable obj.
- Every time you call an object, it will call the constructor as well.
- Object creation can be done in two ways:
1. Declare an object - creating a reference
2. Creating an object - and assigning the value to it
e,g., A obj;
obj=new A();
*new A() shows that you are creating an object.
- Reference of an object is created in the stack.
#2
Anonymous Objects:-
Anonymous objects are simply created by using the new keyword.
- It does not have any reference for an anonymous object.
e.g., new A();
- A method can directly be called using this object.
new A().show();
- We can't use the same anonymous object again. It will be use only for one time.

Whats the use of these anonymous objects?

[@akilankanagaraj41]

When you want to use methods inside another class but don’t want to create an object for it

public class Main{ public static void main(String[] args) {//Main method A a = new A();//Constructor and object creation a.Announcement();//Method call new A().Announcement();//Anonymous object and method call } } class A{//parent class public A(){ //Constructor System.out.println(" Object created."); } public void Announcement(){ System.out.println("NOW in A!"); } }
