Java compile time and TDD?

Question

Java

I'm trying to apply TDD to Java. Simple Hello World project.
Its compilation time is ~4 seconds.
In TDD, as far as I understand, test run time is very important.
In total, in order to run one simple test, it takes me about 4 seconds.
Running a similar test in php takes less than a second.
How do you live with it? How to deal with it? Maybe I'm doing something wrong?

There is something wrong with your car. Late 2012 Macbook Pro runs your test in 0.045 seconds:
