首先卸載JDK

查看當前JDK環境

cd /Library/Java/JavaVirtualMachines
ls

當前的JDK環境為 jdk1.8.0_281.jdk

sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.8.0_281.jdk

然后卸載JRE

To uninstall the JRE, you must have Administrator privileges and execute the remove commands either as root or by using the sudo(8) tool.

sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefpane

與卸載前的設置界面對比可以注意到Java控制面板已經消失了。
