Programming: Stacks

Given a class Stack with the interface

 public void push(char n) // pushes n onto stack public char pop() // return the top of the stack, removing element from stack public boolean isEmpty() // return true if stack is empty

Write a method

public void addStars(Stack stack)

which takes a Stack as input and adds an asterisk (*) at the front and back of all the elements in the stack. The stack must be restored to its original order plus the asterisks. For example, the stack

[bottom] a b c d [top]

Would become

[bottom] * a b c d * [top]
