Make Java syntax work in CMD?

[Kanna]

Hey so I have ran into this issue that java syntax doesn't work in the cmd, but I fixed it before, but accidentally removed the path to regular CMD so when I added it back ofc java doesn't work. So my simple question is how can I add the java path to environment variables at the same time as CMD path?

Do you mean you can't start a Java program from the terminal by typing "java -jar minecraft.jar" or similar? You need to add the Java bin-directory to the "PATH" environment variable: https://www.geeksforgeeks.org/how-to-set-java-path-in-windows-and-linux/

 

Using Java syntax would imply you're writing a Java program in CMD, which seems unlikely.

Yeah that's what I'm trying to do, thanks for the link to a better guide the other one I used said to name path (which overwrites). Also about the syntax thing, It was the word used here by my teacher for the commands "ping" and "attrib" and such, so I made the assumption lol

So I made the mistake of actually not checking function before commenting, and after following that guide it still doesn't work

You also need to adjust your PATH environment variable after creating the JAVA_HOME one:

It would be the PATH, on system variables correct? if so the edit button is grayed out

Yes, correct. You'd need to run as an administrator to be able to update this.

 

As an alternative, you should be able to start Minecraft like this:

%JAVA_HOME%\bin\java.exe -Xmx4096M …

How do I navigate to it so I can run as an administrator?

Can you try opening cmd as admin (right click, run as administrator), then open

sysdm.cpl

 

Spoiler

Yep got it open now that way, now I'm just looking on how to get to the menu you showed, I clicked PATH and edit which was not correct in my case

I just double click or click Edit and the editor shows (Windows 10).

 

I just checked on another machine and I have Path both for my variables and system variables. You could try adding path to your variables and then just adding the path for Java there.

I figured out what I had to do to get that menu to show, I had to type both and separate with a ; so now I got that menu with both in it. But the negative thing here is that java is still

not recognized after a restart, should I just give up and use the tip you gave earlier?

edit : I think I solved it perhaps, I didn't set it to the bin directory, I think I missed that part in the guide sorry for all the confusion done lol it works now

Yeah, that mistake was on me lol. Should have just copied the path I used when it worked once
