问题
how can I use the classes of a package out of the main project where it has been defined? for example imagine there is an Employee class in package people which belongs to ProjectOne. let's assume Employee is needed in another project (ProjectTwo) with the same features.What should I do there?
回答1:
Right-click on ProjectTwo in the Package Explorer. Go to Build Path -> Configure Build Path. Go to the Projects tab, click Add, select ProjectOne, and click OK, then click OK again to exit the project properties window.
Then import your classes as usual - within ProjectTwo, you should be able to see ProjectOne's classes as if they were in the same project.
