Testing Java speed....

There may be a technical term for this....I think it is called "benchmarking".

What I would like to do is test different implementations of a procees written in Java.

For example, I have the same task performed by a method of Object "A" and by a mehtod of Object "B", and I need to know the time difference in the execution between the two. Is there an effective way to do this, aside from a stopwatch?

I looking for an open source tool. I also program with Eclipse, so if there is a tool that integrates with that tool, fabulous! (Although a Google search didn't turn anything up.)

Thanks,

Landon

The most straightwordard way is to do it yourself from the code. For example:
long start = System.currentTimeMillis(); // long running task here long end = System.currentTimeMillis(); System.out.println("long running task took " + (end - start) + " ms");

If you need more detail and accuracy, you can use a profiler, such as JProbe, OptimizeIt, and countless others.

We also have a forum named 'Performance' which deals with this sort of thing in more depth.
