Submitted by Nidhi, on May 06, 2022

Problem statement

In this program, we will get the list of methods of a class using the getMethods() method and print the result.

Source Code

The source code to get the list of methods of a class is given below. The given program is compiled and executed successfully.

// Java program to get the list of methods 
// of a class

import java.lang.reflect.Method;

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

    Method methods[] = cls.getMethods();

    System.out.println("Methods of Integer class: ");
    for (Method method: methods)
      System.out.println(method);
  }
}

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.

In the main() method, we got the list of methods of the Integer class using the getMethods() method and printed the methods using the foreach loop.
