如何从Eclipse导入包？

Question

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?

Answer 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.

Answer 2

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.

Answer 3

在您的新java文件中导入您的包或创建对象，并从您的旧包中获取您想要的java类
