Open Source Tools to calculate Halstead Complexity metrics for Java file [closed]

Question

Are there any open source tools to calculate Halstead Complexity metrics for Java source files.

Answer 1

I was not aware of any open source tool that computes the Halstead metric for Java, but a quick look at Google code search turned up Prest. Obviously, I can't say anything about how good this software is since I only just discovered it.

There is an interesting discussion about the Halstead metric and Java at http://www.virtualmachinery.com/sidebar2.htm.
