How to install JDK 1.6 on Mac OSX Leopard?

How can I install JDK 1.6 on Mac OSX Leopard?

In Software Update today I updated Java, and it upgraded from 1.5.0_26 to 1.5.0_28 (This is not 1.6!). I have Xcode Tools installed, version 3.0. On the download site it 开发者_如何转开发didn't list Mac.

JDK 6 (1.6) is preinstalled in both OS X 10.5 and 10.6. I actually didn't realize this, but it requires 64-bit hardware.

Until Mac OS X 10.7 (currently unreleased), the Java updates were maintained in-house by Apple. In 10.7, Java will no longer be maintained by Apple.

I opened Java Preferences and made Java SE 6 the first version to use
