10 Java dos and dont's

Nice list of 10 Java coding pratices from Data Geekery GmbH in Switzerland. These 10 are close to my programmer heart:

1. Remember C++ destructors
2. Don’t trust your early SPI evolution judgement
3. Avoid returning anonymous, local, or inner classes
4. Start writing [functional interface]s now!
5. Avoid returning null from API methods
6. Never return null arrays or lists from API methods
7. Avoid state, be functional
8. Short-circuit equals()
9. Try to make methods final by default
10. Avoid the method(T…) signature
