How can we create a object of a class without using new operator...

Answer / mamatha

There are different ways to create objects in java:

1. Using new keyword
This is the most common way to create an object in java.

MyObject object = new MyObject();

2. Using Class.forName()

MyObject object = (MyObject) Class.forName("subin.rnd.MyObject").newInstance();

3. Using clone()
The clone() can be used to create a copy of an existing object.

MyObject anotherObject = new MyObject();
MyObject object = anotherObject.clone();

4. Using object deserialization
Object deserialization is nothing but creating an object from its serialized form.

ObjectInputStream inStream = new ObjectInputStream(anInputStream );
MyObject object = (MyObject) inStream.readObject();

5.By using getInstance();
