How to run multiple java files at once?

Question

I have multiple .java files for my hadoop project. How do I execute them without using eclipse?

PS: I use the default ubuntu terminal

Answer 1

You can use javac *.java to compile all the files in the current working directory. As for executing them, use java filename
Where the filename does NOT have the .class at the end. IE, you have MyProgram.java which compiles into MyProgram.class you would type: java MyProgram

You want the run the main class of your project btw (slightly vague, but it might be the only one with a main method).
