Submitted by Nidhi, on March 24, 2022

Problem statement

In this program, we will check an object of an instance of a particular class or not using "instanceof" operator. It returns the Boolean value true, false.

Java program to demonstrate the instanceof operator

The source code to demonstrate the "instanceof" operator is given below. The given program is compiled and executed successfully.

// Java program to demonstrate the example of 
// "instanceof" operator

public class Main {
  public static void main(String[] args) {
    Main m = new Main();

    boolean ret = m instanceof Main;

    if (ret)
      System.out.println("The Object m is an instance of Main class");
    else
      System.out.println("The Object m is not an instance of Main class");
  }
}

Output

The Object m is an instance of Main class

Explanation

In the above program, we created a class Main. The Main class contains a method main(). The main() method is an entry point for the program. Here, we created the object m of Main() class and checked 'm' is an instance of class Main or not using the "instanceof" operator and printed the appropriate message.
