WAP a program in Java to print the reverse of a number input by the user

Explanation:

public class FindReverseNumber {

public static void main(String[] args) {  

 //number defined

 int n;

 int reversedNumber = 0;

 int temp = 0;

 System.out.println("Enter an integer to reverse");  

 Scanner in = new Scanner(System.in);  

 n = in.nextInt();  

 while (number & gt; 0) {

  //modulus operator used to strip off the last digit

  temp = number % 10;  

  //create reversed number

  reversedNumber = reversedNumber * 10 + temp;

  number = number / 10;

 }  

 //output

 System.out.println("Reversed Number is: " + reversedNumber);

}

}

Output:-
