问题
In one of my directories I have all .java files which belong to one package ("game"). Now I want to create one .java file which does not belong to this package and which imports the "game" package. If I create a new file and write import game; then Eclipse complains that it does not know what the "game" package means. Can somebody please help me to solve this problem?
回答1:
You cannot import a package, you need to import classes from that package:
import game.SomeClass;
import game.SomeOtherClass;
or
import game.*;
to import all classes from that package.
Eclipse can generate these imports for you if you type the class-names in your code and press Ctrl+Space for Code-Completion. Select the correct class there (if more classes with the same name exist in different packages), and the import will be generated.

You might also want to use Eclipse's 'Organize imports' shortcut: Ctrl + Shift + O.
This will find all missing types and add the appropriate imports automatically.

import your package in your new java file or create object and get tha java class wat u want from your old package
