卸载java:
https://blog.csdn.net/haozhugogo/article/details/54809545
在“终端”窗口中,复制和粘贴命令:
sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -fr /Library/PreferencesPanes/JavaControlPanel.prefPane
sudo rm -fr ~/Library/Application\ Support/Java
请勿尝试通过从 /usr/bin
删除 Java 工具来卸载 Java。此目录是系统软件的一部分,下次对操作系统执行更新时,Apple 会重置所有更改。
注意:上面是官网的卸载步骤,按照上面的卸载完后,要从finder中进入 /Library/Java/JavaVirtualMachines,然后删除jdk1.8.xxx,这样才算彻底卸载完成
