Setting up enviromental variables in Windows 10 to use java and javac

Question

I got a new laptop with Windows 10 and I want to set it up so I can use java and javac from the command line.

I have searched online but all the guides are for previous versions, and I don't want to mess around with something I don't understand.

Answer 1

Just set the path variable to JDK bin in environment variables.

Variable Name : PATH 
Variable Value : C:\Program Files\Java\jdk1.8.0_31\bin

But the best practice is to set JAVA_HOME and PATH as follow.

Variable Name : JAVA_HOME
Variable Value : C:\Program Files\Java\jdk1.8.0_31

Variable Name : PATH 
Variable Value : %JAVA_HOME%\bin

Answer 2

Here are the typical steps to set JAVA_HOME on Windows 10.

1. Search for Advanced System Settings in your windows Search box. Click on Advanced System Settings.
2. Click on Environment variables button: Environment Variables popup will open.
3. Goto system variables session, and click on New button to create new variable (HOME_PATH), then New System Variables popup will open.
4. Give Variable Name: JAVA_HOME, and Variable value : Your Java SDK home path. Ex: C:\Program Files\java\jdk1.8.0_151 Note: It should not include \bin. Then click on OK button.
5. Now you are able to see your JAVA_HOME in system variables list. (If you are not able to, try doing it again.)
6. Select Path (from system variables list) and click on Edit button, A new pop will opens (Edit Environment Variables). It was introduced in windows 10.
7. Click on New button and give %JAVA_HOME%\bin at highlighted field and click Ok button.
