Hi Chris, Hemorrhage you will. Instead of creating new objects in a loop, reuse existing objects. (This is a good move anyhow to improve the performance of your application.)

I'm a tad fuzzy on working without GC. If I create objects in an inner loop, is that memory lost? Will I not hemorrhage memory like a sieve? (24 years ago, 1-Mar-01, to lugnet.robotics.rcx.java)
