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();
