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.

Solution 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

Solution 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.

  and then click new and add path as C:\Program
  Files\Java\jdk1.8.0_131\bin (depending on your installation path)
  and finally click ok
• Next restart your command prompt and open it and try javac

Solution 4

To find the env vars dialog in Windows 10:

Right Click Start
>>  Click Control Panel  (Or you may have System in the list)
>>  Click System
>>  Click Advanced system settings
>>  Go to the Advanced Tab
>>  Click the "Environment Variables..." button at the bottom of that dialog page.

Solution 5

Its still the same concept, you'll need to setup path variable so that windows is aware of the java executable and u can run it from command prompt conveniently

Details from the java's own page: https://java.com/en/download/help/path.xml That article applies to: •Platform(s): Solaris SPARC, Solaris x86, Red Hat Linux, SUSE Linux, Windows 8, Windows 7, Vista, Windows XP, Windows 10

while it says at the top that it applies to win 10, there is no section for win 10. Is it the same as win 8?

Try and see if you can find the similar things in windows 10 corresponding to windows 8 that u see in the link. The underlying concept hadn't change set path to tell windows where to look at to run your commands that u dont want to have to type out the full directory of that command

Do not forget to restart the terminal, i.e. the "cmd", (not the computer) through which you checked the "java -version" or wanting to run any other program using CLI

Since the Java folder doesn't exist on a new Windows10 installation, that is a misleading and worse than useless response.

@johnrubythecat a java 8 / windows 10 setup can be done with a jdk directory tree like what's used in this answer.

Just to update my orignal answer. I have found RapidEE to be a much better way of editing/maintaining env vars in windows: rapidee.com/en/about
