No, there isn't any equivalent of async/await in Java - or even in C# before v5.
It's a fairly complex language feature to build a state machine behind the scenes.
There's relatively little language support for asynchrony/concurrency in Java, but the
java.util.concurrent package contains a lot of useful classes around this. (Not quite equivalent to the Task Parallel Library, but the closest approximation to it.)
