header files in Java?

Hi again.
In C++, you declare your class in a ".h" file, and define it in a ".cc" file. How do you do that for Java?

You define it in a .java file. There's is really no parallel in Java with the C/C++ convention of declaring a class.

Java uses import statement similar to #include statement of C/C++ for importing packages in which classes are grouped together....

The difference is that in C if you #include a file, there is overhead associated with it, while in Java if you import a jar (or group of files) only the classes that are actually used in the compiling get pulled in. There is no penalty for getting carried away with how many files that you import.
