推荐答案

没有要下载的JAR或任何额外的安装，这些类是JDK的一部分Mac OS X.在Apple Java 6 JDK中，它们位于JDK包下的 Contents / Classes / ui.jar 中（例如 / System / Library / Java Oracle Java上的/JavaVirtualMachines/1.6.0.jdk 或 /Library/Java/JavaVirtualMachines/1.6.0_37-b06-434.jdk ） 7它们位于JRE主目录下的 lib / rt.jar （ / Library / Internet Plug-Ins / JavaAppletPlugin.plugin / Contents / Home 或 /Library/Java/JavaVirtualMachines/jdk1.7.0*.jdk/Contents/Home/jre ）。

There is no JAR to download or anything extra to install, the classes are part of the JDK on Mac OS X. In Apple Java 6 JDKs they live in Contents/Classes/ui.jar under the JDK bundle (e.g. /System/Library/Java/JavaVirtualMachines/1.6.0.jdk or /Library/Java/JavaVirtualMachines/1.6.0_37-b06-434.jdk), on Oracle Java 7 they are in lib/rt.jar under the JRE home directory (/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home or /Library/Java/JavaVirtualMachines/jdk1.7.0*.jdk/Contents/Home/jre).
