Java and Objective C are quite similar (actually if you read the original Java whitepaper, you'll find that it borrowed a number of ideas from Objective C when it was created).

Java's great particularly for cross-platform development - you can write a single app and compile it for a number of platforms (with Mac OS X currently being the best :-).

Objective C is worth learning too. In some ways it's less forgiving that Java, but in others it's more flexible and arguably more readable. Anyhow, once you've learned one, the other is probably a day or so of extra learning away.
