You can also create a Java project by clicking Ctrl + Shift + P at the same time. Type in java create, and click on the Java: Create Java Project.

If you want to disable the parameter help box, in VSCode, on the bottom left there is a gear icon. Click on that, select settings. Search for "Java Inlay". Scroll down to where you see:
*JavaScript › Inlay Hints › Parameter Names: Enabled*
In the dropdown menu, select None. Scroll down a bit further and you'll see another:
*Java › Inlay Hints › Parameter Names: Enabled*
*Java › Inlay Hints › Parameter Names: Exclusions can be used to disable the inlay hints for methods.*
Once again, in the dropdown menu, select None.
Alternatively, you can open the settings.json file. To open this, press Ctrl+Shift+P at the same time, type in "settings.json" and select "Preference: Open User Settings (JSON)". Add this to the JSON file:
"java.inlayHints.parameterNames.enabled": "none",

Error pls help ig its about PATH idk how to fix it

[@cemre6263]

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.

[@spurthim4528]

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

[@LoStFoReVeRiNtImE]

Use code runner extension

[@shades3692]

At first, the terminal was unresponsive, but closing and opening VSC fixed my issue. Great video, man thx a lot!

[@gringotico1759]

Thanks for that. Was experiencing this issue.

[@DrBiography]

Thank you so much for providing this video, I recently have been struggling to figure out how to run java in visual studio code, this video helped me figure it out, I just liked and subscribed.

[@bimaltwayana2058]

best tutorial ever. Best short and sweet and correctly taught how to install. Thank you so much sir.

[@bunny11111]

this one better be helpful cuz I've been figuring how to run a java code on visual studio.

[@AlgoJaz]

how do you get rid of the path line?

[@Nornfang]

As a man who hates eclipse, thank you

[@Нурлан-в8л]

thank you, this video helped me a lot. I don't really know English, but you do useful things. Thanks❤

[@DavidCourtney]

I'm just trying to run the Hello World example, but when I click on Run, I get "Homework1.java is a non-project file, only syntax errors are reported" in the Problems tab.

[@duhanavc6773]

did you solve it I get the same message

[@DavidCourtney]

@@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.

[@diego-fc8ym]

its because of the "x:" i removed that and it finally worked

[@williamkiarie9669]

I really appreciate your tutorials Kenny, I was able to successfully install the java code pack for vs code. 😉🙂🙂

Idk after opening vs code ita sending me to redhat website ? I followed your steps

[@lemmeGoHome]

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..

[@emperordrex5927]

Please I need help I set up and installed it but it isn't showing on my cmd also I can't tag my java file in my html it just won't work

[@Uday_Aravind]

Thank you sir, I can run the codes now. Very helpful.

[@beyzaaaaaaaaaaaaaaaaa]

Thanks firstly i downloaded it like you did. But now im gonna download latest version from oracle. (Teacher request )So there will be two jdk on my laptop. İs that could cause any problem? and how can i use my latest jdk on vscode (after add path )

[@beyzaaaaaaaaaaaaaaaaa]

Hello, I want to ask something. Every time I open the vs code, a message saying "Java projects are opening, check the details" appears. It wasn't there before, is it normal? The laptop gets very hot while this is happening, that's why I asked.

[@Azero-hr4cr]

I did all the steps but still my code did not appear

[@The_moonlit]

If it doesnt work, keep running the program and clicking finish+launch vscode. After enough time it will work.

[@PrathameshTusharPatil]

hello sir
when i started to run my java program ,it is taking time and showing some issue so what could be the problem ??
its always showing the following content :
Initiating server activation
Request to kill LSP server.
