Got any code like this?
public boolean foo(int x) {
if (x>2) {
return true;
} else {
return false;
}
}
My goodness! That's five lines of code to do something pretty basic. Run this thru PMD's SimplifyBooleanReturns and it'll suggest reducing this to:
public boolean foo(int x) {
return x>2;
}
This is a fair bit easier to read - and as a bonus, you shave four bytes off the class file! Good times.
For more on this sort of thing, get the PMD book!
