Do you mean the version of java you are running? Then yes, java -version.

Do you mean the latest java that Sun has to offer? java.sun.com?

I'm not sure I get your question.

Going by your user name, every_answer_gets_a_point, shouldn't you give Jeff an upvote ? – gareth_bowles Mar 4 '10 at 4:53

yes i gave him an upvote, but two others gave him downs – alexluvsdanielle Mar 4 '10 at 5:04

I'm pretty sure Downs is hereditary. As for Java, the newest available version is Java 6u18. – Emyr Mar 4 '10 at 11:33
