The new frontier for learning Java

BigDateExperiment.java

This is an experiment I did some time ago, I was curious about the biggest date which is possible to represent in Java using the famous time in milliseconds since the great midnight of the new years eve of 1970 and the most far date in the future representable with a Calendar object. It's been an interesting findings. I hope to see the new millennium bug for the end of the milliseconds in a long.
