How to run a java file from a different folder using linux terminal

Question

I want to run a compiled .java/.class file that is located in a subfolder from the folder I am currently working in. I ran the command:

locate -br ^TheFileIWantToRun.java

so I know that the file is in the filepath:

/home/Me/Desktop/Folder1/Folder2/TheFileIWantToRun.java

I need to run this file from my current working directory:

/home/Me/Desktop/Folder1/

And I need to pass it a text file called test.

I have tried:

java -cp /home/Me/Desktop/Folder1/Folder2 TheFileIWantToRun test

But I get the error:

could not find or load the main class TheFileIWantToRun

Typically if the .java/.class file were in the same folder I would use:

java TheFileIWantToRun test

and this works.

How do I accomplish running a file from a different folder than the one I am in? Thank you.

have you checked that your folder-structure represents your package structure defined in the .java file? — ParkerHalo

why not just cd into that directory, call the program there and give it the full path to the text file ? — Marged

@Marged the reason is that I am creating the test text file while in the current directory and I am trying to avoid going back and forth between directories. — lefunction

I suggest you try the following :

java -cp /home/Me/Desktop/Folder1/Folder2 TheFileIWantToRun test

If test is not in the current directory then you should provide the full file path.

When I try the above it says could not find or load main class .home.Me.Desktop.Folder1.Folder2.TheFileIWantToRun

I have just edited my answer, I tried it my self and it worked for me, it's like the one you have already posted with your question. Are you using any package naming for your class ? Why don't you provide the Java file so we can take a look at it !

hmmm, it seems that both answers (including the one you posted previously) are the suggested route. There maybe something specific to the system I am using that prevents me from doing this. I am using a virtual machine that was set up for me, so I will check with that person to find if there is something else I need to do. Thanks for your help.
