Knowledge of a language is a scale and not a binary yes / no question.
Being passingly familiar with a language is a week exercise, putting it on your resume / CV and saying you're ready to write production quality code is different.
For Java specifically:
- How does the JVM memory model and other internals work?
- How comfortable am I with the standard library?
- What are the idioms and design patterns used by professionals in Java?
- Performance pitfalls that are tribal knowledge with concurrency / threading, etc?
If the scale of language knowledge is 0-10, getting to 3, where you're familiar with the syntax, common language features and a few APIs is a week's exercise after you've used a few languages (in the same family -- I'm not going to be passingly familiar with Haskell in a week).
