Language Tricks to Shorten My Java Code?
- by yar
I am currently rediscovering Java (working with Ruby a lot recently), and I love the compilation-time checking of everything. It makes refactoring so easy. However, I miss playing fast-and-loose with types to do an each loop. This is my worst code.
Is this as short as it can be? I have a collection called looperTracks, which has instances that implement Looper. I don't want to modify that collection, but I want to iterate through its members PLUS the this (which also implements Looper).
List<Looper> allLoopers = new ArrayList<Looper>(looperTracks.length + 1);
for (LooperTrack track : looperTracks) {
allLoopers.add(track);
}
allLoopers.add(this);
for (Looper looper : allLoopers) {
// Finally! I have a looper
I'm particularly concerned about any features that are new to Java from 1.5 on that I may have missed. For this question I am not asking about JRuby nor Groovy, though I know that they would work for this.
Edit: Sorry (too much Ruby!)... looperTracks is of type LooperTrack[] and LooperTrack implements Looper.
