Default method on interface implementing
Abstract:
Developpers happen to forget to implement concrete classes on creating new implementations. Indeed, IDEs fill methods content with canonical return values, (null for object, 0 for numerics, etc.). Consequently, errors appear only on deployment stage, when it is not on running.
To avoid this, here is the tip I use: raising a default exception. If unit tests are generated, then the exception is raised on development stage, which is better than after one hour compiling / deployment / execution ;-).
Process:
On IntelliJ IDEA, open:
- Project Settings
- File Templates
- Code
- Implemented Method Body
- write:
throw new UnsupportedOperationException("Class Name : ${CLASS_NAME} - Method Name : ${METHOD_NAME}");
- Code
- File Templates
