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

This is a Java program that demonstrates how to list all the methods of a class using the getMethods() method of the Class class.

In the main() method, the program uses the Class.forName() method to get the Class object associated with the java.lang.Integer class.

The program then uses the getMethods() method of the Class object to get an array of all the public methods of the Integer class. This method returns an array of Method objects that represent the public methods of the class.

The program then uses a for loop to iterate through the array of Method objects and print each method to the console using the println() method. When the program is run, it will output a list of all the public methods of the Integer class to the console.

Source Code

import java.lang.reflect.Method;
public class ListMethods
{
	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 m: methods)
		{
			System.out.println(m);
		}
	}
}

Output
