Scanner in = new Scanner(System.in);
System.out.print("Enter first number: ");
int p = in.nextInt();
System.out.print("Enter second number: ");
int q = in.nextInt();
KboatSwap obj = new KboatSwap(p, q);
System.out.println("Values before swap:");
obj.display();
obj.swap();
System.out.println("Values after swap:");
obj.display();
