I always hear that programmers try to pick the right tool for the job. I've never programmed in Java, so I was wondering What are its benefits? Why is it so popular? What should I use it for?
I just program recreationally. Is there anything about it that makes it particularly fun??

It opens a few resources (e.g. files, database connections, remote streams) and processes it. It works a few minutes and then it exits. Let's say it's in Java (if the language is relevant)
In object-oriented programming, the open–closed principle states "software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification"; that is, such an entity can allow its behaviour to be extended without modifying its source code.
I think after 12 years or so, the "write once, run anywhere" mantra is almost true. Writing Java code pretty much isolates you from the platform dependent aspects of the systems on which you deploy it.
