In this article we will learn to implement a Java program to find the reverse of a given number. A Java program is provided below which reads a number from the user and prints the reverse of that number:
Program is as follows:
import java.util.Scanner;
public class Driver
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
System.out.println("Enter a number: ");
int n = input.nextInt();
int rev = 0;
while(n != 0)
{
rev = rev * 10 + (n % 10);
n = n / 10;
}
System.out.println("Reverse of the given number is: " + rev);
input.close();
}
}
Input and output for the above program are as follows:
Enter a number:
157
Reverse of the given number is: 751
