Java Program to Reverse an Array Using Loops

Welcome to CodeWithBK — your go-to hub for mastering Java programming.

In this video, we will learn how to write a Java program to reverse an array using loops. Reversing an array is one of the most common and important problems in Java programming, and it helps in building strong fundamentals of array manipulation and loop control.

In this video, you will:
Understand the logic behind reversing an array
Learn how to implement the solution using loops in Java
Reverse array using an auxiliary array, the original array remains unchanged
Reverse array in place without using an auxiliary array, the original array changes
Work step by step to swap elements from both ends of the array
See how to write clean and efficient code for array problems
Practice a program commonly asked in exams and coding interviews

Why learn this program?
The reverse an array program in Java is a very popular coding problem that tests your understanding of arrays, indexing, and loop control. It helps you learn how to approach problems logically and optimize solutions. By the end of this video, you will know exactly how to reverse an array step by step using loops in Java.

If you are preparing for *Java coding questions*, *board exams*, or *interview practice*, this tutorial will be very useful.
