Question

Compared with other languages, Java sometimes is pretty “chatty” and some of the core libraries are considered cumbersome by a lot of programmers. Over the last years an tremendous zoo of small libraries has evolved, which try to “fix” a single aspect of these e.g. Joda Time, guava-libraries, lambdaj

What are the top three libraries that can improve productivity when working with core Java?

Answer 1

I can definitely mention

1. Guava
2. Guice – dependency injector
3. ICU4J – unless all your users live in the same place
4. Mockito – mocking framework
