Puzzle 4 - Solution

The solution to the last puzzle is,

import java.util.Scanner;
public class Swap{
 
        static int  temp;
        public static void swap(int num1,int num2){
             System.out.println("Original nos are-Num1 : " 
+ num1 + " Num2 : " + num2);
             if(num1 > num2){
                while(num1 > num2){
                    num1--;temp++;      
                           }
                while(temp >0){
                    temp--;num2++;
                           }
            }
            else{
               while(num1 < num2){
                   num1++;temp--;      
                          }
               while(temp <0){
                   temp++;num2--;
                          }
            }
            System.out.println("Swaped nos are-Num1 : "
 + num1 + " Num2 : " + num2);
   }

   public static void main(String args[])
   {
     int num1,num2;
     swap(new Scanner(System.in).nextInt(),
          new Scanner(System.in).nextInt());
   }
}

Sorry no correct answers this week!
