{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.print("Enter a: ");

int a=sc.nextInt();

System.out.print("Enter b: ");

int b=sc.nextInt();

swap(a, b);

}

static void swap(int a, int b)

{

System.out.println("Before swapping, ");

System.out.println("a: "+a);

System.out.println("b: "+b);

int c=a;

a=b;

b=c;

System.out.println("After swapping, ");

System.out.println("a: "+a);

System.out.println("b: "+b);

}
