Different ways to create objects in Java

Different ways to create objects in Java:

Here are four different ways to create objects in java:

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.
