How Many Ways We Can Create the Object in Java

There are many ways to create Object in Java  some of them listed below

1. Using new keyword

This is the most common way to create an object in java. I read somewhere that almost 99% of objects are created in this way.

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();

Now you know how to create an object. But its advised to create objects only when it is necessary to do so.

5.Using ClassLoader

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