As you know, in Eclipse you can turn on "Unnecessary 'else' statement" check that will trigger on if-then-else with premature return. And, from my experience, there are two most possible situations when use such statement:
1) Pre-check:
if (validate(arg1)) {
return false;
}
doLotOfStuff();
2) Post-check:
doLotOfStuff();
if (condition) {
return foo;
} else {
return bar;
}
In the second case, if the trigger is on, Eclipse will suggest you to change the code to:
doLotOfStuff();
if (condition) {
return foo;
}
return bar;
However, I think that the return with else statement is more readable as it is like direct mapping of business logic. So I am curios if this "Unnecessary 'else' statement" code convention is widespread or else statement is more preferable?
