推荐答案

如果你的机器上没有旧的JDK，你需要使用GUI并下载Java更新程序。我能找到的离你最近的是适用于Mac OS 10.5的Java 1.6.0_15（你没有提到你正在运行的Mac OS X版本）：

If the older JDK isn't on your machine, you'd need to use the GUI and download the Java updater. The one closest to yours I could find was for Java 1.6.0_15 for Mac OS 10.5 (you didn't mention which Mac OS X version you were running):

我没有看到Mac OS X 10.6的任何内容。为此，您可能必须为每个10.6版本下载更新程序，并从更新程序中提取JDK安装程序（使用） Pacifist

I didn't see any for Mac OS X 10.6. For that, you would probably have to download the updaters for each 10.6 release, and extract the JDK installer from the updater (using something like Pacifist

哦，如果您还没有，请尝试运行/ Applications / Utilities / Java Preferences.app，它允许您更改默认的Java你的机器在你安装的机器中。

Oh, and if you haven't already, try running /Applications/Utilities/Java Preferences.app, which lets you change the default Java on your machine amongst the ones you have installed.
