Different ways of creating object in java

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()

If we know the name of the class & if it has a public default constructor we can create an object in this way. It is also known as reflection.

 

MyObject object = (MyObject)Class.forName(“com.abc.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) Using reflection in another way.

this.getClass().getClassLoader().loadClass(“com.abc.myobject”).newInstance();
