I'm trying to do some benchmarking of JVMs running on various hardware and OS platforms. I've created an algorithm to exercise the parts of the JVM I'm interested in and intend to run this algorithm many times to find a decent average.

It then automatically terminates th...
I have been studying Java for a few months and am now starting to learn C. I am a little confused, I was under the impression that passing an object by reference and passing a pointer to that object were the same thing: I thought the difference was that in Java all passing of objects is done with pointers automatically, where as in C o...

I need to model some information about seasons, and need to track them based on start / end date in a year-agnostic way. I.e. I need to allow users to define summer as being between, say, May 15th and September 10th, and do that for all years. I'll need to do a lot of checking of the type isThisDateInSeason). All the date manipulati...

I just had a pretty painful troubleshooting experience in troubleshooting some code that looked like this: try { doSomeStuff() doMore() } finally { doSomeOtherStuff() } The problem was difficult to troubleshoot because doSomeStuff() threw an exception, which in turn caused doSomeOtherStuff() to also throw an exception. The s...
