Swapping numbers

                                         Normal swapping

public class Swap {
   
 public static void main(String[] args) {
  int a =90;
  int b =50;
  a = a+b;
  b = a-b;
  a =a-b;
  System.out.println("A value is "+a);
  System.out.println("B value is "+b);
}
}


                                                       Swapping through method


public class Swap
{
    public static void m1(int a,int b)
    {
        int x= a;
        a=b;
        System.out.println("The nassigned value of a is--->"+a);
        System.out.println("The nassigned value of b is--->"+b);
        a=x;
        System.out.println("Swaped value of a to b is-->"+a);
        System.out.println("Swaped value of b to a is-->"+b);
     }

 public static void main(String[] args) {
 
  m1(10, 20);
}
}
