Reviewing / testing / refactoring code efficiently
Updated: you should check out this 40-minute presentation. The stuff below covers just one of his recommendations: testing code that changes often, in case your VCS is SVN.

this.expCorrStops = expCorrStops;
this.iso = iso;
this.aperture = aperture;
this.shutter = shutter;

}
this.effectiveIso = function(){
return this.iso * this.amplification();
}

Controlling Java integer cache
Useful for autoboxing.
By default, Integer.valueOf caches between -128 and 127 (min/max. of signed byte). However, you can increase this range by using:
-XX:+AggressiveOpts
and/or
-Djava.lang.Integer.IntegerCache.high
when launching the VM.
