Reverse a Number Program in Java with Source Code

|

Reverse a Number Program in Java with Source Code – Reversing a number means swapping the first digit with the last digit, the second digit with the second last digit, and so on until the middle element.

To reverse a number, perform the following steps: multiply the number’s modulo by 10.

We have included a downloadable zip file at the end of the program so that you may run the following codes.

Example Program:

  package reversenumberprogram;

import java.util.Scanner;
public class ReverseNumberProgram {
    public static void main(String[] args) {
        int a, res = 0, n;
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter a number");
        n = sc.nextInt();
        while (n != 0) {
            a = n % 10;
            res = (res * 10) + a;
            n = n / 10;
        }
        System.out.println("reverse of a number is " + res);
    }

}

Output

What is the importance of a Program to reverse a number in Java?

Java is a powerful and reliable object-oriented, cross-platform programming language with outstanding memory management and security capabilities.

It also supports multithreading, allowing you to write code that accomplishes numerous tasks at the same time.

In the United States, there are also 11,611 monthly posted positions. Java is a popular programming language.

It powers Android apps, server apps, banking apps, Big Data technology, and much more. It’s a skill that will benefit programmers for many years to come.

As a result, beginners should focus on learning this easy problem project.

What is the use of the Reverse number java program?

The Java StringBuffer class’s reverse() method is used to replace this character sequence with the reverse of the sequence.

If the sequence contains any surrogate pairs, the reverse operation treats them as a single character.

The REVERSE function takes a character expression as an argument and returns a string with the ordinal positions of all logical characters reversed.

The REVERSE function’s argument cannot be of a user-defined data type.
