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();
