Java Program to Iterate Over Arrays Using for and for-each Loop

Java Program to Iterate Over Arrays Using for and for-each Loop

Last Updated : 26 Nov, 2024

In Java, arrays are a collection of elements of the same type. To access and manipulate elements, we can use iteration techniques such as the for loop and for-each loop (also known as the enhanced for loop).

Program to Iterate Over Arrays Using for and for-each Loop in Java

In the below example, we will demonstrate how to iterate through an array using both the traditional for loop and the simplified for-each loop.

Example:

Java

// Java program to iterate over an array 
// using for loop and for-each loop
public class Loop {
  
    public static void main(String[] args) {
      
        int[] n = {1, 2, 3, 4, 5};

        // Using for loop
        System.out.println("Using for loop:");
        for (int i = 0; i < n.length; i++) {
            System.out.println(n[i]);
        }

        // Using for-each loop
        System.out.println("Using for-each loop:");
        for (int num : n) {
            System.out.println(num);
        }
    }
}

Output

Using for loop:
1
2
3
4
5
Using for-each loop:
1
2
3
4
5

Explanation: Here, both loops print the same array elements, but the for-each loop simplifies the iteration by eliminating the need for an index.

How to Print an Array in Java Without using Loop?

Given an array arr in Java, the task is to print the contents of this array without using any loop. First let's see the loop method. Loop method: The first thing that comes to mind is to write a for loop from i = 0 to n, and print each element by arr[i].Pseudo Code: for(int i = 0; i < Array.lengt

Java Program to Compute the Sum of Numbers in a List Using For-Loop

Given a list of numbers, write a Java program to find the sum of all the elements in the List using for loop. For performing the given task, complete List traversal is necessary which makes the Time Complexity of the complete program to O(n), where n is the length of the List. Example: Input : List

Java Program to Add an Element to ArrayList using ListIterator

In this article, we will learn how to add an element to ArrayList using ListIterator. The ListIterator is used to return a list iterator over the list elements. The listIterator() returns an iterator over the list from the beginning, but the listIterator(index) returns an iterator over the list from

Java Program to Convert an Array into a List

In Java, arrays and lists are two commonly used data structures. While arrays have a fixed size and are simple to use, lists are dynamic and provide more flexibility. There are times when you may need to convert an array into a list, for instance, when you want to perform operations like adding or r

Java Program to Print the Elements of an Array

An array is a data structure that stores a collection of like-typed variables in contiguous memory allocation. Once created, the size of an array in Java cannot be changed. It's important to note that arrays in Java function differently than they do in C/C++As you see, the array of size 9 holds elem

Java Program to Increment All Element of an Array by One

Given the array, the task is to increment each element of the array by 1. Complete traversal is required for incrementing all the elements of an array. An optimized way to complete a given task is having time complexity as O(N). Examples: Input : arr1[] = {50, 25, 32, 12, 6, 10, 100, 150} Output: ar
