So I guess this project is kind of worthless since there are already plenty of Java virtual machines around, but I was curious about internals of the JVM so I put this together. I have a couple interesting ideas for it that I might implement later.
So I started this on Tuesday night (January 27, 2009) and posted
this Sunday (February 1, 2009) so there isn't even a weeks worth of
work in it, specially since during the week I only have time to work
on it nights.
It does currently run some small Java programs.
The only classes I have implemented are
System.out.println(I) and a System.out.println(F) just so programs
can output something to compare against Suns JVM. Many of the Java
instructions aren't implemented yet either and there isn't a lot of
bounds checking so it's not very safe. So here is my to do list if
I ever decide to finish it:
In the download below there is a Testing.java. I combined the following three commands to create this text file:
