Java Import Static error

Question

I have this import source :

import static   MinecraftDungeonTileTypes.*;

on class in same package as the class MinecraftDungeonTileTypes

source of class:

package mod.dungeonworld;

public  class MinecraftDungeonTileTypes {
    public static  int TILE_WALL = 0;
    public static  int TILE_ROAD = 1;
    public static  int TILE_DOOR = 2;
    public static  int TILE_CHEST = 3;
    public static  int TILE_ROOM = 4;
    public static  int TILE_COD = 5;
    public static  int TILE_SPAWNER = 6;
}

What I get Is an compilation error:

Description Resource Path Location Type The import MinecraftDungeonTileTypes cannot be resolved.

When I use the static members of class MinecraftDungeonTileTypes regularly without static import I get no compile error. What is causing that?

You can't statically import a non static class but you can import statically it's static fields / attributes:

In order to access static members, it is necessary to qualify references with the class they came from. For example, one must say:

Import single attribute (use * instead of name to import massively)

import static mod.dungeonworld.MinecraftDungeonTileTypes.TILE_WALL;

You will refer in the code as TILE_WALL.

Or import the class

import mod.dungeonworld.MinecraftDungeonTileTypes;

You will refern to same attribute in the code as MinecraftDungeonTileTypes.TILE_WALL.

"You can't statically import a non static class but you can import statically it's static fields / attributes" Nice info, but since OP doesn't do that, it is not really related to this question.

The problem comes from that I haven't written the full path of the class I want to import. Here is solution in my case:

import static   mod.dungeonworld.MinecraftDungeonTileTypes.*;
