Mac下同时安装多个版本的JDK

Mac自带了的JDK6，安装在目录：/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/下。

JDK7，JDK8则需要自己到Oracle官网下载安装对应的版本。自己安装的JDK默认路径为：/Library/Java/JavaVirtualMachines/jdk1.8.0.jdk

1. 在用户目录下的bash配置文件.bashrc中配置JAVA_HOME的路径：

export JAVA_6_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

text = text.rotate(45)
