Tom and Jerry found two bags of apples. The bag that Jerry chose contains 5 apples and the bag chosen by Tom has 3 apples. Tom wants to have more apples, so he swaps the bags. Write a program to display the apples in the two bags before and after swapping. Hint :-( Try using call by value and call by reference; Write which can be used to swap)

te.b = s.nextInt();

te.swap(te);
