Different ways to create an object in java



There 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("javatechinfo.corejava.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.
