elobrate your question.

2 solutions

Solution 1

Method which return values and are not defined with void must return values in every case or as the compiler complains every execution branch.

Most likely you have a if statement and after it you have not written a return or you have a try catch and you have not defined the return after the catch etc.

True, my 5, but mentioning exception would be important, see the answer by Shmuel.

Solution 2

If the return value of a method isn't void, the method has to return a value or throw an exception.
Check that the whole of the paths in the method ends with return statement (or an exception) or put a return statement at the end of the method.
