You can iterate through an array in reverse order using For-Each loop like below: public class Main { public static void main(String[] args) { int arr[] = {2,3,1,4,7,6}; int i = arr.length-1; for(int e: arr){ // do something System.out.print(arr[i] + "\t"); i--; } } }

Dec 28, 2020 · We can iterate the list in reverse order in two ways: Using List.listIterator () and Using for loop method. Using IntStream range (int startInclusive, int endExclusive). Approach 1: Using List.listIterator () and Using for loop method. Syntax: Return Value: This method returns a list iterator over the elements in this list (in proper sequence).

Apr 4, 2025 · The Collections class in Java provides a static method to reverse the order of elements in a specified list: Collections.reverse(list); The reversed list can then be used to iterate backward over the original elements: for (String item : list) { System.out.println(item); }

Mar 19, 2015 · In about half the cases, the list (an ArrayList) is being iterated in reverse order by using an index today. Can someone suggest a cleaner way of doing this (since I dislike the indexed for loop when working with collections), though it does work?

Jun 6, 2013 · Java uses 0-based array indexes. When you create an Array of size 10 new int[10] it creates 10 integer 'cells' in the array. The indexes are: 0, 1, 2, ...., 8, 9. Your loop counts to the index which is 1 less than 11, or 10, and that index does not exist.

In this article you will learn how to iterate over a Java list in the reverse order. Introduction A simple approach of iterating a list in the reverse order may consist in simply revert a list using Collections.reverse() and then performing a natural iteration over the elements.

This tutorial covers different methods to iterate backwards through lists in Java, which is particularly useful in problems that require reverse traversal, such as undo operations, backtracking algorithms, and more.

Use a standard for loop to iterate in reverse. Here's how you can do that: Convert the List to an array and iterate the array in reverse order using a for-each loop.

May 20, 2022 · We will learn how to reverse an Array in Java by using a simple for loop, using ArrayList, using StringBuilder.append( ), using ArrayUtils.reverse( ) and more.

Dec 9, 2024 · We have multiple ways to iterate an array in reverse order. Example 1: The most simplest way to iterate over an array in reverse order is by using a for loop. Example 2: The other method is using an enhanced for loop, where we first …
