My Eclipse can compile but I can't find a JDK!

Question

I've installed Eclipse on a Windows machine some time ago. A couple of days back I was doing some Java coding and I noticed I don't have a JDK, but still Eclipse could compile & run the Java classes. Does it have a compiler included?

Answer 1

Yes Eclipse contains it's own incremental compiler.

An incremental Java compiler. Implemented as an Eclipse builder, it is based on technology evolved from VisualAge for Java compiler. In particular, it allows to run and debug code which still contains unresolved errors.

For some history take a look here:

Yes. And here's some more characters.
