删除mac jdk

查看jdk

ls /Library/Java/JavaVirtualMachines/

jdk1.7.0_71.jdk jdk1.8.0_111.jdk jdk1.8.0_241.jdk

删除jdk

sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk

删除了上面的jdk，其实终端上还可以看到java -version

那还得删除啊

sudo rm -fr /Library/Internet/Plug-Ins/JavaAppletPlugin.plugin

sudo rm -fr /Library/PreferencesPanes/JavaControlPanel.prefPane

sudo rm -fr ~/Library/Application/Support/Java
