how to compile java and import it as package

hi:

I am new to Java and meet a problem when compiling the codes. The codes are as following:

Code :

---

 
import com.testing.simpletest.*;
 
....

---

the main problem is I don't know how to include the files in directory and how to combine them into
one package, and how to name the package. Is there any difference between them and .h files in C.
If I use eclipse as IDE, and create my own project, how to import these packages.
Thanks.

Create a jar file for the java files that you have(com.testing.simpletest.*.class). Then add the jar file to your eclipse project. Then execute the project.It may work.

Java doesn't use header (.h) files, so there is no similarity at all with C in that respect.
