How many ways we can create object in java?

How many ways we can create object in java?:
===================================

We can create object in java in 5 ways:

1. By using NEW keyword

2. By using new Instance (Reflection API)

3. By using clone() method

4. By using Deserilization

5. By using class loader

1. By using new Keyword: Most commonly we use create object in java by using new keyword

Whenever we use new in java object is going to be created

package com.rameshsoft.keys;

public class Test {

    String name = "RAMESHSOFT";

   

    public void hello() {

         System.out.println("WELCOME TO RAMESHSOFT: " +name);

         System.out.println("MASTERS IN JAVA WITH SELENIUM REAL TIME: " +name);

    }

   

    public static void main(String[] args) {

         //creating object using new keyword

         Test test = new Test();

         test.hello();

        

    }

}

2.By using clone() method

We can create object using clone() method as well. this method is present in Object class(java.lang.Object)

syntax of clone() method:

public Object clone();

package com.rameshsoft.keys;

public class Test {

    String name = "RAMESHSOFT";

   

    public void hello() {

         System.out.println("WELCOME TO RAMESHSOFT: "+name);

         System.out.println("MASTERS IN JAVA WITH SELENIUM REAL TIME: " +name);

    }

   

    public static void main(String[] args) throws CloneNotSupportedException {

         //creating object using new keyword

         Test test = new Test();

         //creating cloned object using clone() method

         Test testClone = (Test)test.clone();

         testClone.hello();

        

    }

}

3. 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.

Syntax:

Test test=(Test) class.forName("JDBC.........").newInstance();

4. using object deserialization

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

Syntax:

ObjectInputStream istream=new ObjectInputStream(some data);

Test test=(Test) instream.readObject();

5. By using class loader
