Clarifying some terms

What was the name of the term for the file? Like example.java. In System.out.printf, System is the class, out is the field, and printf is the method?

Han,

I think the System class documentation will clear it up for you nicely.

As you said, System is the class, out is the field, and printf is the function. However, there is a little more to it. The field - out - is a static PrintStream object that provides a lot of functionality like the printf convenience method.

Regards,

Chris

The file example.java would be the source file. It is the file containing the source code.

Hope that helps!
