There are too many Java JDK versions installed on the mac, and it is planned to delete them all and reinstall the latest version of JDK.

Open a terminal and enter the following command:

sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin 
sudo rm -fr /Library/PreferencesPanes/JavaControlPanel.prefpane



// 2、查找jdk

// 3、删除jdk
// 删除对应版本jdk
sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk
