Incompatible Type When Using Interface

Question

I have an interface: public interface Generator { ... }
I have a class that implements the above interface:
public class MySQLGenerator implements Generator { ... }
In my main program, I have:
Generator g = new MySQLGenerator();
The error message I got is "incompatible types
found: MySQLGenerator
required: Generator"

Answer 1

Check your classpath, and that you are actually importing the Generator you think you are. Also check that there's no other class named Generator in your classpath - the only reason I can think of for what's happening is that there's another Generator class somewhere that's being used. This would explain the invalid reference compilation error.
