Determining the version of Java SDK on the Mac

Question

I have a MacBook Pro running Snow Leopard; how can I see what version of the Java SDK is installed on my Mac?

Answer 1

Open a terminal and type: java -version, or javac -version.

If you have all the latest updates for Snow Leopard, you should be running JDK 1.6.0_20 at this moment (the same as Oracle's current JDK version).
