Visual Studio Code can't find JDK8

I am currently trying to compile and run Java in VSC using redhat's extention and the code runner extension, though every time I try to "Run code," it tells me "Java runtime could not be located," and in the output: "'javac' is not recognized as an internal or external command, operable program or batch file." So I went into settings to tell VSC the path to my JDK. I went to "Java configuration" and inserted "java.home": C:\Program Files\Java\jre1.8.0_144 into the settings, though it gives me another error stating "Value Expected (2, 18)". This is where I'm stuck currently:

Where I'm Stuck Currently

I have also tried the directory to my JDK bin with the same results. What am I doing wrong?

I had the same problem today, after a few hours trying to find why it stoped working, came to my solution. Java updated and there was an empty older vesion folder left in the c:\program files\java, just deleted and everything is working again.

For everyone who ended here with an jdk installed through asdf:

It turned out I did not update my JAVA_HOME env variable properly.

Setting it like documented here solved the problem for me: https://github.com/halcyon/asdf-java#java_home

I fixed the issue by downloading OpenJDK from Red Hat openjdk and placing the extracted file in directory C:\ as in the image(I have renamed the file name from "java-1.8.0-openjdk-1.8.0.191-1.b12.redhat.windows.x86_64" to "java-1.8.0-openjdk-1.8.0.191" for simplicity) And change user settings in VS Code as USER SETTINGS and change workspace settings in VS Code as WORKSPACE SETTINGS

I have faced the same problem if you are on Windows machine then open folder C:\Program Files\Java\ and look for the newest version of JDK in my case it's "jdk1.8.0_144" then enter on the right side following:

`{
     "java.home": "C:\\Program Files\\Java\\jdk1.8.0_144"
 }`

If you don't have at least 1.8 then install a new one! because VS code doesn't support older versions!

Your error says you need to put in double Slashes.

If you are on Linux then use normal slashes "/"

Don't forget to save and restart VS code afterward to apply changes! Have a nice day

The format of syntax is wrong. Instead of writing - 

    "java.home": C:\Program Files\Java\jre1.8.0_144

this should be written -

    "java.home": "C:/Program Files/Java/jdk1.8.0_144"

Use slash (/) instead of backslash () in file path and put quotes around it. Do recheck that jdk 8 or later is installed.

Please install Java Debugger like RedHat Extension.

These two things are compulsory to install -

  1. Language Support for Java(TM) by Red Hat - already installed .
  2. Java Debugger for Visual Studio Code - Install this one .

Here is a shortcut -

vscode:extension/vscjava.vscode-java-pack

Copy and paste above line in the browser address bar and press 'Return(Enter)'. the extension will open in the VSC, Install and reload the editor.
