I went through some of topics, but didn't find a proper anser. I'm trying to import class to other class, but I get "The import "classname" cannot be resolved" error. Both classes are in the same package. What can cause the problem? I also tried to clean my project.
If both classes are in same package, you don't have to import it.

Good morning everyone!
I did a project x but all my files were out of order so I decided to group them by folders.
foldera
---ClassA.java
---ClassB.java
folderb
---Class1.java
Main.java
The problem arises when I try to compile, since in the main it appears that the classes I made are not found
I thought this could be solved by putting in the classes
package src.foldera.ClassA;
And in the others the same
package src.foldera.ClassB;
And
package src.folderb.Class1;
So in all classes
And in the main put
import src.foldera.*;
import src.folderb.*;
But I keep getting the same error even though I put the packages
It should be noted that I did not create the folders in the code editor, rather I did it in the same Windows 10 File system
What is this about? Thanks!
Assuming a standard setup where the src folder is the root of your source hierarchy, the statements should be:
package foldera;
package folderb;
The imports should be similarly shortened to:
import foldera.*;
import folderb.*;
You have to define the package in which the class is in.
As an example in classA:
package src.foldera;
And in class1:
package src.folderb;
import src.foldera.ClassA;
I have to write an extension code and am confused. Here's what I have:
import info.gridworld.actor.Bug
public class ZBug extends Bug
With the rest my code below that. I keep getting an error message saying that "the import info cannot be resolved" I'm not sure what I'm doing wrong
You are missing a semicolon at the very least:
import info.gridworld.actor.Bug;
Then, you may miss some of the dependencies.
Make sure that the info.gridworld.actor.Bug class or the JAR which contains it is in the project's build path.
If it is a Maven project, make sure to include the required <dependency>.
Trying to import import GUI.layouts.RXCardLayout; but it can't be resolved. It is an extension of CardLayout that someone made and I found it online. Anyone know what the right import is?
I assume you are talking about this RXCardLayout.
There are no special imports. It doesn't use a package. You just add the source to you project and compile the source code into your class path.
Maybe the problem is you need to add a package statement to put the code into the same package as your other source code.
I imported the samples of Sphero-Android SDK to my workspace. TwoPhonesOneBall project gives compiler errors. In ConnectionActivity.java class, the following imports cannot be resolved.
//...some imports
import orbotix.multiplayer.LocalMultiplayerClient;
import orbotix.multiplayer.MultiplayerControlStrategy;
import orbotix.multiplayer.MultiplayerGame;
import orbotix.multiplayer.RemotePlayer;
//...imports
How can I fix it? Since these classes don't exist, I didn't come up with a solution. I searched the net but I couldn't find similar problem. By the way,the same problem also occurs in MultiplayerLobby application.
I am getting that error :
The import android.graphics.TableMaskFilter cannot be resolved
But I have seen TableMaskFilter class in android.graphics package of android-sdk folder and I am unable to see it inside the android4.0.3 library in Eclipse.
You can't. TableMaskFilter is annotated with #hide, which means it's definition is stripped from android.jar.
