So I'm pretty new to Java and this is my first semester. Can anybody help me out and tell me what I'm getting wrong here in my "okUserName() method"? I keep trying to work on it but I'm definitely stumped. Also I have an alternate driver class with a main method & a file in the same folder, but everything is perfect there.

*mind the awful indentation I just copy and pasted from my ide.

Hi Don,

I don't know whether i understood completly your actual problem or not.

But when i take the code to my IDE, i found two compiler error.

1) writeFile(): no need of handling FileNotFoundException there, because no code throwing this checked exception.

2) okUsername(): should return boolean value. Method should have a default return type irrespective of the return statement which is there in condition scope.

Thanks,
Rajasekar.

Please, please, please post your code in code tags.

I believe the problem with your okUserName() method is that you have a return statement in an if clause (or in if clauses). When the compiler sees this, it assumes it is possible that the if clauses will never be executed so that a return may never occur, causing the error, method x() must return <something>. A way to correct this is with an else statement:



That way the compiler will see there will always be a value returned.
