无法从终端运行Java程序

Question

I recently created and compiled a Java program, but it will not run from the Terminal. It isn't the program, because it WILL run from Eclipse. This is what I get from Terminal when I attempt to run the program:

Grants-MBP:~ Grant$ java /Users/Grant/Desktop/Pythagorean
Exception in thread "main" java.lang.NoClassDefFoundError: /Users/Grant/Desktop/Pythagorean
