There are four different ways to create objects in java:
1. By using new keyword
This is the most common way to create an object in java. Almost 99% of objects are created in this way.
MyObject obj = new MyObject();
2. By 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 obj = (MyObject) Class.forName("org.mahi.MyObject").newInstance();
3. By using clone()
The clone() can be used to create a copy of an existing object.
MyObject obj = new MyObject(); MyObject clonedObj = (MyObject) obj.clone();
4. By using object deserialization
Object deserialization is nothing but creating an object from its serialized form.
ObjectInputStream ois = new ObjectInputStream(anInputStream ); MyObject obj = (MyObject) ois.readObject();
