How is object created in java?..

Answer / chantiraji

There are FIVE different ways to create objects in Java:

1. 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 object = new MyObject();//normal way
2. By Using Factory Method:

ClassName ObgRef=ClassName.FactoryMethod();
Example:

RunTime rt=Runtime.getRunTime();//Static Factory Method
3. By Using Cloning Concept:

By using clone(), the clone() can be used to create a copy of an existing object.

MyObjectName anotherObject = new MyObjectName();
MyObjectName object = anotherObjectName.clone();//cloning Object
4. 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.

MyObjectName object = (MyObjectNmae) Class.forName("PackageName.ClassName").newInstance();
Example:

String st=(String)Class.forName("java.lang.String").newInstance();
5. Using object deserialization:

Object deserialization is nothing but creating an object from its serialized form.

ObjectInputStreamName inStream = new ObjectInputStreamName(anInputStream );
MyObjectName object = (MyObjectNmae) inStream.readObject();
