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.

[@kvelez]

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!");
}
}
