# infix-to-postfix-calculator

A postfix calculator that utilizes Java Swing and an infix to postfix algorithm to process user-inputted mathematical expressions to calculate a numeric value.

# Reason

I wanted to get some experience with creating a GUI, and Java Swing was an easily-accessible and manageable way to implement a calculator GUI. This project helped me learn how to use event listeners and learn how to implement the shunting-yard algorithm (infix to postfix) to preprocess user-inputed expressions to be computer readable.

# Future improvements

- Add event listeners to keyboard keys to make it easier for clients to input expressions

- Make implicit multiplication and division with parenthesis

- Add other operations (log, sin, cos, tan, ..., etc)
