who can we create the object of a class? in how many ways we can create it (max 5)..

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

MyObject object = new MyObject();

2. Using Class.forName()
If we know the name of the class & if it has a public
default constructor we can create an object in this way.

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();
