In this program, we will check whether an object represents an interface type or not using the isInterface() method.

Program/Source Code:

The source code to check whether the specified Class object represents an interface type or not is given below. The given program is compiled and executed successfully.

// Java program to check the specified Class object 
// represents an interface type

public class Main {
  public static void main(String[] args) throws ClassNotFoundException {
    Class cls1 = Class.forName("Main");
    Class cls2 = Class.forName("java.lang.Runnable");

    boolean res1 = cls1.isInterface();
    boolean res2 = cls2.isInterface();

    System.out.println("Is Main an interface : " + res1);
    System.out.println("Is java.lang.Runnable an interface : " + res2);
  }
}
Java

Output:

Is Main an interface : false
Is java.lang.Runnable an interface : true

Explanation:

In the above program, we created a public class Main that contains a main() method. The main() method is the entry point for the program. Here, we checked whether an object represents an interface type or not using the isInterface() method. The isInterface() method returns true if the specified object represents an interface otherwise it returns false.
