Question

Write a Reverse Polish Notation (RPN) calculator in Java.

Write a Stack class for doubles:
- constructor and push, pop, empty, peek functions.
- Use an array implementation for the stack (or a linked list if you did this before class on 3/5).
- If you want, you can limit the stack size to ten (HP only had three on their first attempt!), but in that case you should make your push do nothing if the stack is full. Most modern stack implementations have no arbitrary size limit.
- The pop and peek methods should throw an exception if they are called on an empty stack (see code for this below).
Write a RPN class:
- constructor (takes a String expression, e.g. "3 4 5 + *") and an evaluate method which returns a double ("3 4 5 + *" would evaluate to (4+5)*3=27).
Write a RPNCalculator class:
- main method with whatever accouterments you see fit.
Allow the user to type in an expression, then evaluate it and repeat until they say quit.
