Java Program to reverse an array elements


In this program, You will learn how to reverse array elements in java.


List is: 1 2 3 4 5

After reverse List is: 5 4 3 2 1

Example: How to reverse array elements in java.

import java.util.Scanner;

class Main {
    public static void main(String args[]) {

        int i, j, temp;
        int arr[] = new int[5];
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter 5 numbers:");

        for (i = 0; i < 5; i++) {
            arr[i] = sc.nextInt();
        }

        j = 5 - 1;
        for (i = 0; i < j; i++) {
            temp = arr[i];
            arr[i] = arr[j];
            arr[j] = temp;
            j--;
        }

        System.out.print("After Reverse list:");
        for (i = 0; i < 5; i++) {
            System.out.print(" " + arr[i]);
        }

    }
}

Output:

Enter 5 numbers:10 20 30 40 50
After Reverse list: 50 40 30 20 10
