Problem statement

Write a Java program to add elements in ArrayList and print them in reverse order.

Printing elements in reverse order

To print elements in reverse order, we are running a loop from N-1 (Here, N is the total number of elements in the ArrayList) to 0.

To get the total number of elements of ArrayList, we use size() method of ArrayList class.

Java program to print ArrayList elements in reverse order

Here, we are creating an ArrayList, adding 5 elements (100, 200, 300, 400 and 500) and printing them in reverse order.

import java.util.ArrayList;
 
public class ExArrayList {
 
  public static void main(String[] args) {
    ////Creating object of ArrayList
    ArrayList arrList = new ArrayList();
   
    //adding data to the list
    arrList.add("100");
    arrList.add("200");
    arrList.add("300");
    arrList.add("400");
    arrList.add("500");
   
    System.out.println("Array List elements: ");
    //display array list elements in reverse order
    for(int iLoop=arrList.size()-1; iLoop >= 0; iLoop--)
      System.out.println(arrList.get(iLoop));
   
  }
}

Output

The output of the above example is:

Array List elements: 
500
400
300
200
100
