Program/Source Code:

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

// Java program to get the simple name of 
// the class

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

    System.out.println("The class name associated with cls: " + cls.getName());
    System.out.println("The simple class name associated with cls: " + cls.getSimpleName());
  }
}

Output:

The class name associated with cls1: A
The class name associated with cls2: Main

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 got the simple name of the "java.lang.String" class using the getSimpleName() method and printed the result.
