This is the fourth solution to find the reverse of an integer value, by using the core logic of forming the number in the reverse order.

import java.util.Scanner;

public class ReverseOfInt {

		public static void main(String[] args) {
			// TODO Auto-generated method stub

			@SuppressWarnings("resource")
			Scanner intInp= new Scanner(System.in);
			
			//Input an Integer
			System.out.println("Enter an Integer=");
			int numValue=intInp.nextInt();
			System.out.println("The integer is="+numValue);
			
			int numBackup = numValue, revNum=0, rem;
			while (numValue!=0) {
				rem=numValue%10;
				revNum=revNum*10+rem;
				numValue=numValue/10;
			}
			System.out.println("The reverse of number="+numBackup+" is="+revNum);
		}
}
Try it >>
Output:
 Enter an Integer=
 361
 The integer is=361
 The reverse of num=361 is=163
