Program/Source Code:

The source code to create a method returning an object is given below. The given program is compiled and executed successfully.

// Java program to create a method 
// returning an object

class Sample {
  void sayHello() {
    System.out.println("Hello World");
  }

  Sample retObj() {
    return this;
  }

}

class Main {
  public static void main(String args[]) {
    Sample X1 = new Sample();
    Sample X2 = X1.retObj();

    X1.sayHello();
    X2.sayHello();
  }
}

Output:

Hello World
Hello World

Explanation:

In the above program, we created a Sample class and public class Main. The Sample class contains two methods sayHello() and retObj(). The sayHello() method is used to print the "Hello World" message and the retObj() method returns the current object using the "this" keyword.

The Main class contains a static method main(). The main() is an entry point for the program. Here, we created 2 references of Sample class and called the sayHello() method and printed the "Hello World" message.
