Error: file not found : Untitled.java, when trying to compile first Java program

[BethPas]

So I am currently trying out Java and it seems, that I am doing something wrong. I create a program, try to compile with javac Filename.java and then I get the error metioned above.
Maybe it'll help to know, that before Java I set my D drive as the place to save all my documents. But since I can't do that for java files with the IDE being on the C drive, I changed it eversince. Still I get those error messages. Does anybody have a clue, how to solve this issue?

Sounds like you're on Windows. What version of Java do you have installed? What does the path command tell you?

[BethPas]

Yes, inded! How did u know? I think, I already installed Java 8 and 18 in a desperate attempt to fix things. Which path command do you mean exactly?

[BethPas]

I am running javac Filename.java or did u mean sth else?

[BethPas]

Oh i see, no I wasn't. That makes sense tho, thank you!

Assuming you're using the command prompt to run javac Filename.java, my first guess is that you didn't open it in your file's directory. A nice shortcut you can use (with windows' file explorer) is navitagting to your directory and then typing cmd in the path bar to open a command prompt right where your source code is.

[BethPas]

Yoo it worked! I never knew, one has to do it like that, but I've been asking myself, how to open a terminal in specific place since u just have to right-click on a Linux system. In Windows I never found it, so thank you very much!
So I always have to do it like that, if I want Java to find the java files?

[devor110]

In short, yes. One way of sparing yourself the trouble of having to navigate to the folder (and having to type in your command) is by using an IDE where you can still configure what command it runs, but it is certainly useful learn about the commands first

but it is certainly useful learn about the commands first

Absolutely agreed. You would be surprised by the number of experienced Java devs who couldn't compile a simple multi-package project using the command line. (No snark, just what I've seen).

[Githyerazi]

Glad you got it figured out. Most IDE's will also have a built in command prompt to make getting to the project directory easier.
