Java Applets

The Calculator

This applet was originally written in Semester 2, 1999, as an assignment for the SENG112 ("Software Engineering II") subject at uni.

To use the calculator, just type a simple mathematical expression in the text field, using only numbers, +, -, *, /, (, ). Pressing the calculate button will attempt to evaluate your input.

This applet only works properly on version 4 browsers and better... Also note that since the classes are loaded on an "as needed" basis, the first calculation may take a minute of two to perform...
