LispExpressionEvaluator
CSC220 Programming Project#2
http://joeganley.com/code/jslisp.html (GUI)
- / must have at least one operand
- Implement the given MyStack class
- Design and implement an algorithm that uses MyStack class to evaluate a
- Valid tokens in an expression are '(',')','+','-','*','/',and positive integers (>=0)
- Display result as floting point number with at 2 decimal places
- Negative number is not a valid "input" operand, e.g. (+ -2 3)
- There may be any number of blank spaces, >= 0, in between tokens
(/(+20 30))
- Must use MyStack class in this project. (*** DO NOT USE Java API Stack class ***)
- Must throw LispExpressionException to indicate errors in LispExpressionEvaluator class
- Must not add new or modify existing data fields
- Must implement these methods in LispExpressionEvaluator class:
public LispExpressionEvaluator()
public LispExpressionEvaluator(String inputExpression)
public void reset(String inputExpression)
public double evaluate()
private void evaluateCurrentOperation()
- You may add new private methods
