As you can see I'm trying to run a Java program but I need the command which I can write in terminal to run the code.

I imagine the easiest way would be to press the blue arrow at the top.

If it has to be command line though, try

Javac Main.java

To compile the source to byte code which will give you a Main.class file, then

Java Main

To run it. The oracle website has a quick guide here

Run java classfile from terminal

If you run java folder/somefile java tries to find a class somefile in the package folder, but your class isn't located in the package folder, it's just located in the path folder. You can adjust the search path for classes using the -cp option (meaning classpath).

For example having a class YourClass in the package your.package, this package is located in /your/path you can execute it from any location with:

java -cp /your/path your.package.YourClass

In your specific case you should run:

java -cp folder somefile

I hope it's clear enough ;-)
