who can we create the object of a class? in how many ways we
can create it (max 5)
Answer Posted / chandni jain
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();
