Leap Years is a simple program written in the esoteric language ArnoldC. Its function is to determine if a year is a leap year.
To use Leap Years, download the compiled leap-years.class file from the bin directory. cd to the parent directory and run java leap-years. You will be asked for a year and the program will tell you if it was a leap year or not.
Note: Leap years were not introduced until 1752, so any year before that will return false.
