If a class calls another, can I put them in separate JAR files?

Let's say I have two classes Airport and Airplane:

public class Airport
{
    public static void main(String args[])
    {
        Airplane a1 = new Airplane();
    }
}

public class Airplane
{
    int seats;
    public Airplane()
    {
        seats = 10;
    }
}

I want to put these classes in separate JAR files so that I can develop them independent of each other in future in case any issue comes up. Since Airport calls Airplane I have to import Airplane in the Airport source file. I was thinking of importing them in the project that I will use to call these classes. But even if I import both of them in project, there still are issues about resolves.

UPDATE: Can you give an example .classpath to accomplish this call hierarchy? I simply added JARs to the .classpath of Main Project but Airport complains that it can't find methods of Airplane.

Yes, you can import Airplane into Airport even if these classes are in different JARs. However, both JARs must be present in the classpath.
