The method "getPill()" is set up to return a String. Fine. But look at this code snippet:
You can't have any executable code immediately following a "return ..." statement because there is no way the code can reach that point, which is what the compiler is explaining. There are a couple of ways of correcting this. You can us an "if/else if/else" construct. Or you can set the med type within the "switch()" construct and remove the "return" statements, placing one return at the end of the method. Also, it looks like you're trying to return multiple pills in some cases. But the method says it return a single String. If you want to return multiple values, you'll need to use and Array or ArrayList or some other collection. Give it a try and post again if you run into additional problems.
