Update:
更新：
First Remove the java runtime

(Now you can close and reopen the System Preferences window to see that the icon is gone)
Uninstall java JDK
In the terminal run this First, go to java directory
cd /Library/Java/JavaVirtualMachines
And then use “ls” at the prompt to see if there is anything in there. In my case, there was. So then you'll type in the following:
sudo rm -rf jdk
Then press tab to autocomplete java version.
To check java is gone
java
it should give
No Java runtime present, requesting install
首先删除java运行时
sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefpane
（现在您可以关闭并重新打开“系统偏好设置”窗口以查看图标消失了）
卸载 Java JDK
在终端运行这个首先，转到java目录
cd /Library/Java/JavaVirtualMachines
然后在提示符处使用“ls”查看是否有任何内容。就我而言，有。那么你将输入以下内容：
须藤rm -rf jdk
然后按 Tab 键自动完成 java 版本。
检查java消失了
爪哇
它应该给
No Java runtime present, requesting install
