Creating Objects in Java: Beyond Constructors

When crafting objects in Java, using the constructor is a go-to approach. However, there are additional avenues to consider.

Alternate Creation Methods

Java offers four primary ways to instantiate objects:

1. new Keyword: This familiar method is widely employed and involves explicitly calling a class's constructor.

   MyObject object = new MyObject();

2. Class.forName(): This approach comes in handy when you know the class name and it has a public default constructor.

   MyObject object = (MyObject) Class.forName("subin.rnd.MyObject").newInstance();

3. clone(): If you have an existing object, you can duplicate it using the clone() method.

   MyObject anotherObject = new MyObject();
   MyObject object = (MyObject) anotherObject.clone();

4. Object Deserialization: This process involves creating an object from its serialized form.

   ObjectInputStream inStream = new ObjectInputStream(anInputStream );
   MyObject object = (MyObject) inStream.readObject();
