How do I find where Java is installed on Windows 10?

Question

I recently installed Java (Java Runtime 1.8.121) to my machine. I need to set up JAVA_HOME and set the variable from the Java folder where it installed.

Everywhere I have looked online says the Java folder should be located in Program files (x86), however, it is nowhere to be found. Its not in program files (x86), not in program files. I wasn't able to choose a destination when it was installed as Software center was used. It simply completed the installation.

Can someone please help me find where the Java folder is so I can set up JAVA_HOME???!

Can you execute java --version on the command line? If so, try where java. – Purington

If he want to set up JAVA_HOME i guess java XXX command will not be available, am i wrong? – Alurta

@Alurta possibly. But PATH and JAVA_HOME are separate environment variables, so maybe PATH is set. – Purington

baeldung.com/java-check-is-installed "as with java -version, this command is only useful if our PATH environment variable points to the bin directory." – Urticaria

java -version will work without JAVA_HOME – Urticaria

This might help: baeldung.com/java-home-on-windows-7-8-10-mac-os-x-linux – Urticaria

Does this answer your question? superuser.com/questions/1148677/… – Urticaria

What distribution of Java did you install? AdoptOpenJDK/Temurin (old adoptopenjdk)/ORACLE JDK... ? Maybe post a site from which you downloaded Java. Installations of different JDK's / JRE's can have different paths. – Alurta

I think the superuser question might have answered it. I checked Java control panel, which shows that it's actually in C: > ProgramData > App-V > 758738 > 3232234 > Root > VFS > ProgramFilesX86 for some reason. – Lebna

Strangely enough CMD did not work - entering "where java" brought back "INFO: could not find files for the given pattern". – Lebna

Because its in program data, which is hidden, I can't use it to set up JAVA_HOME. Does anyone know if I can just move the Java folder elsewhere? Straight into my C: Program files x86? Without it messing anything else up? – Lebna

Please, use your APP-V client! ...then you (probably) can: java -version, where java, ... – Dealt

Answer 1

• cmd:

  where java
  

• git bash (same as cmd or):

  which java
  

• powershell:

  (get-command java.exe).Path
  

  • Superuser: Equivalent of cmd's "where" in powershell

java_home is java_home, but this "solution" considers %PATH% only !;) – Dealt

when I do "where java" in cmd I just get "INFO: could not find files for the given patterns" – Lebna

it means: it is not on/your installer didn't (successfully) modify the %PATH% ... App-V: doesn't that mean that you are/use java in a "virtual environment"!? ;) social.technet.microsoft.com/Forums/en-US/… – Dealt

(get-command java.exe).Source also works. – Striker

Answer 2

Open a command prompt

type: wmic product where "Name like '%%Java%%'" get installlocation,Name

This command can take a minute to complete. But should return something like this.

Edit: The benefit of this command, is that it doesn't rely on any system environment variables. It searches for installed programs that have the word 'Java' in the name. It won't return extra files or locations.
