Also there is a difference between 'doing Java' and being a Software Engineer writing code in Java (or whatever other language makes sense or makes you happy).

Also there is a difference between 'doing Java' and being a Software Engineer writing code in Java (or whatever other language makes sense or makes you happy). For sure you can find people 'doing Java' but I wouldn't allow them to commit a single line of code into anything I care about or want to be associated with. It's not about how much code you produce (which 'doing Java' sounds like) but what quality you produce and how little code you write to make your project do what it should do. That's exactly where these two kinds of people differ. With 10 years+ I would hope a developer is in the second part and wouldn't hire someone still being in the first one.
