I'll throw one more in here. I've noticed several uses of for loops, but you don't even need anything inside the loop. I mention this only because the original question was trying to find less verbose code.
int[] toArray(List list) {
int[] ret = new int[ list.size() ];
int i = 0;
for( Iterator it = list.iterator();
it.hasNext();
ret[i++] = it.next() );
return ret;
}
If Java allowed multiple declarations in a for loop the way C++ does, we could go a step further and do for(int i = 0, Iterator it...
In the end though (this part is just my opinion), if you are going to have a helping function or method to do something for you, just set it up and forget about it. It can be a one-liner or ten; if you'll never look at it again you won't know the difference.
