I solved it. To solve this problem go cmd and type java -version javac -version The versions must be same ex: 17.0.8 if they are different than press windowkey + R and type sysdm.cpl than go advanced than go envromental variables and check JAVA_HOME in user variables and PATH in system variables. Be sure that you checked the first variable in PATH if they are different for example JAVA_HOME shows 17.0.8 version and 8.1.0 in PATH (first/top variable) than you must delete 8.1.0 in PATH and you should put 17.0.8 version of javac to top of PATH with clicking edit. After all click ok buttons and restart cmd and vsc. It should work now.

I am not able to run the program….. I mean it’s not working is there any kind of extension to be installed??

Use code runner extension

hello how do i restart vscode? do i have to uninstall?

@@somename7104 no no no! just press the x button thats all!

did you solve it I get the same message

@@duhanavc6773 In my case, the problem turned out to be that I had a bad setting in the settings.json file located at C:\Users\\AppData\Roaming\Code\User I deleted the settings.json file and everything started working. The reason my settings.json file was messing up Java was because I had been experimenting with Rust programming about a year prior, and my settings.json had some lines in there to get cargo working for Rust. And for whatever reason, those settings were conflicting with what Java was trying to do. Rather than figure out how to make the settings.json file work with Java while keeping my Rust settings, I opted to just delete the settings.json file ... and Java started working for me. Given that my particular situation probably doesn't match yours, I'm guessing what I did won't help you, but you can give it a try.

same is happening with me. it's wanting me to install a JDK from there

Yeah, apparently we need to download a JDK separately for the Java programs to get compiled..

help me

@@nhp.1411 check my pinned comment!

same no one has a solution for this

I found the answer : If you do not want to have them in your editor, you can set the setting java.inlayHints.parameterNames.enabled to none

Thanks for bringing this up! I posted the solution as a pinned comment

same for me

do u have find the solution ?

@@bubule_ I ended up reinstalling java

@@alvinkennethmayega1113 ok thank's

It’s included in the kit in the video, you need it to compile and run java

should be enough to just download the vscode java coding pack as it includes the JDK already.

@@KennyYipCoding okay thank you

You have to search for it, it won’t automatically show it unless you’ve used the command before

@@KennyYipCoding yes, i've been search it but its still not show up. Now i'm just try to install jdk 17 to replace my jdk 20 and hope the java project will show

Did you install the Java code pack for vscode?

There are also vscode extensions for Java included in the installation

@@KennyYipCoding finally bro, i found the problem that the pack doesn't automatic install the PROJECT MANAGER FOR JAVA. So the problem only on this thing. Thankyou so much bro

I solved it. To solve this problem go cmd and type java -version javac -version The versions must be same ex: 17.0.8 if they are different than press windowkey + R and type sysdm.cpl than go advanced than go envromental variables and check JAVA_HOME in user variables and PATH in system variables.

Thanks for sharing this!

@@nathanwillett6918 idk i didn't even download it again, i just installed another one

No, it comes directly from Microsoft

Part of an extension pack you have to download

Which one?

Or else it might have been hidden So click the 3 button on top right side u’ll find Run or debug
