Reverse order of all elements of ArrayList

Reverse order of all elements of ArrayList


import java.util.ArrayList;
import java.util.Collections;

public class ReverseAllelement {
   
    public static void main(String[] args) {
        ArrayList<String> arr = new ArrayList<String>();
        // add element in arraylist
        arr.add("c");
        arr.add("php");
        arr.add("html");
        arr.add("java");
        // print arraylist
        System.out.println("Before Reverse ArrayList Is = " + arr);
       
        Collections.reverse(arr);
       
        System.out.println("After Reverse ArrayList Is = " + arr);
    }

}

Output:

Before Reverse ArrayList Is = [c, php, html, java]

After Reverse ArrayList Is = [java, html, php, c]
