Java return value (in try/catch clause)

Question

everyone. I have a rookie question about the returning value in java. Here\'s my code.

@Override
public long addDrugTreatment(long id, String diagnosis, Stri         


        

Answer 1

In Java (or any other C-like language) all control paths must return a value.

If an exception is thrown inside the try then the return will not be executed and so you are not returning a value on all possible control paths.

You have to either:

1. add a return after the try-catch or
2. add a return inside each catch or
3. add a finally with a return.
