Problem Solution:

In this program, we will get the name of the generic superclass using the getGenericSuperclass() method and print the result.

Program/Source Code:

The source code to get the name of the generic superclass is given below. The given program is compiled and executed successfully.

// Java program to get the name of the 
// generic superclass

public class Main {
  public static void main(String[] args) throws ClassNotFoundException {
    Class cls1 = Class.forName("Main");
    Class cls2 = Class.forName("java.util.ArrayList");
    Class cls3 = Class.forName("java.lang.Object");

    System.out.println("The generic superclass is: " + cls1.getGenericSuperclass());
    System.out.println("The generic superclass is: " + cls2.getGenericSuperclass());
    System.out.println("The generic superclass is: " + cls3.getGenericSuperclass());
  }
}

Output:

The generic superclass is: class java.lang.Object
The generic superclass is: java.util.AbstractList<E>
The generic superclass is: null

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 get the name of the generic superclass using the getGenericSuperclass () method and printed the result.
