I'm getting a missing return statement error at line 87 and I can't figure out what I'm missing :/

What will be returned from legalHex when valid is true and str.length() is 0? Hint: the loop body will not be executed.

oops no that was a copy/paste error. I fixed that. The only error I'm getting on the compiler is the missing return statement on line 80. Sorry. Wrote the wrong line.

In the method legalHex(), at the if(valid), is valid is true and the loop doesn't run, because the condition is false, then nothing is returned. Which is illegal.

thank you all for your help. Everything is compiling and running the way it is supposed to, except that decimalValue is supposed to be returning the values set in hexValue (I think - my professor's wording is v difficult to understand), but it is not returning the right numbers. I think the issue is my arithmetic. Anyone have any thoughts? Thanks so much!

Do you have a specific example of what is wrong? I've tried a few numbers, and it seems to work.
