Array Initialization and Traversal

This program demonstrates initialization and traversal of a single dimensional array.

Problem Statement

Write a Java program to initialize an integer array with 5 elements and print them sequentially.

Source Code

1 public class ArrayInitializationTraversal {
2 public static void main(String[] args) {
3 int[] arr = {10, 20, 30, 40, 50};
4 for(int i=0; i<arr.length; i++) {
5 System.out.println("Element at index " + i + ": " + arr[i]);
6 }
7 }
8 }

Program Output

Element at index 0: 10
Element at index 1: 20
Element at index 2: 30
Element at index 3: 40
Element at index 4: 50

Explanation

The array arr is initialized with 5 integers, and arr.length provides the size used by the for loop to iterate from index 0 to 4, accessing each element with arr[i], demonstrating basic array initialization and traversal and how arrays store multiple values in contiguous memory.
