Eclipse中的导入类问题

Question

I have 2 packages each in a different project , one package is called ch6 which includes class X , the other package is game which includes class Gamer , when trying to import game.Gamer manually in XI get error : "The import game cannot be resolved " , but when I hover on the red line of the error and choose "fix project setup.." , a dialog box appears offering importing the project of class game to the path of project of X and things are fixed, why can't I add the game.Gamer manually although I use the same syntax ?

* EDIT *

Including code as requested:

project ch6:

package ch6; 

abstract public class X {
    private int x = 7;
    public static final int y = 24;
} 

project HFJ:

package game;

public class Gamer {
    public int z;
}

Answer 1

If you have two Eclipse projects it should look something like:

[Project ch6]
  -java
  -Build Path
   ....
[Project game]
  -java
  -Build Path
  ...

To import cross project you want -> (you can get to the path a number of ways)

  [right click] ch6 -> Properties -> Build Path  
  Projects Tab -> Check [game] || (add) Project [game];

Then do a clean build. That should resolve the import and combine the paths.

edit: reversed the order per Ed's suggestion.

Answer 2

I think you might see this if you didn't use the correct directory structure - if game.Gamer.java wasn't stored as /game/Gamer.java.

Also, if you haven't already, try refreshing the project (select the project in the tree, then menu File..Refresh.
