What is the Simplest Way to Reverse an ArrayList?

 What is the Simplest Way to Reverse an ArrayList?

Do Check My Video On Utility Classes:

Reverse the element of the list

mehtod : public static void reverse(List l)

Example:

  

import java.util.ArrayList;

import java.util.Collections;

public class Test{

    public static void main(String[] args) {

        ArrayList l = new ArrayList();

        l.add(3);

        l.add(333);

        l.add(23);

        l.add(33);

        l.add(43);

        l.add(36);

        System.out.println(l);//[3, 333, 23, 33, 43, 36]

        Collections.reverse(l);

        System.out.println(l);//[36, 43, 33, 23, 333, 3]

    }

}

o/p:

[3, 333, 23, 33, 43, 36]

[36, 43, 33, 23, 333,3]
