"Organize" JDK & Macos X

How do I install the JDK on MacOS X?

To Oracle's website, download the JDK file (which should be a DMG file) used by the MacOS operating system. After the download is complete, go to the local, locate the DMG file that you just downloaded, double-click it and follow the prompts to install it step-by-step.

After the installation is complete, open terminal, enter the command: Java-version and then enter, you can see Java version information similar to the following.

Java version "1.8.0_111" Java (tm) SE Runtime Environment (build 1.8.0_111-b14) Java HotSpot (tm) 64-bit Server VM (Build 25.1 11-B14, Mixed mode)

If a similar message appears, this version of jdk1.8.0_111 is currently installed on your computer.

How do I uninstall the JDK installed on MacOS X?

This is very easy. For example, I want to uninstall jdk1.8.0_73.

Enter the following command to enter the directory where the JDK1.8.0_73.JDK is stored

Cd/library/java/javavirtualmachines

Then enter the following command

sudo rm-rf jdk1.8.0_73.jdk
