    Default newbie question: Error: Could not find or load main class Java Result: 1

    Hello all,

    I am trying to learn java and I have this error several times:

    Error: Could not find or load main class chinese1.Chinese1
    Java Result: 1
    BUILD SUCCESSFUL (total time: 2 seconds)

    As you can guess the project name is chinese1.
    But the same problem happened in several other projects, it starts ok then I make a change in the code and I get this error.
    Even If I delete or make comments on the new code it doesn't help!!
    In the chinese1 project i even make a comment of all the code and still has this error!!



    /*

    * and open the template in the editor.
    */
    package chinese1;

    //import java.io.FileInputStream;
    //import javazoom.jl.player.Player;

    /**
    *
    * @author Tiksuv
    */
    public class Chinese1 {

    /**
    * @param args the command line arguments
    */
    public static void main(String[] args) {
    // TODO code application logic here
    // Chinese ChForm = new Chinese();
    // ChForm.setVisible(true);
    //
    // try {
    // FileInputStream file= new FileInputStream("C:\\ChineseWords\\tu3.mp3");
    // Player playmp3= new Player(file);
    // playmp3.play();
    //
    // } catch (Exception e){
    //
    // }

    }
    }


    I don't get it.
    I work with Netbeans 7.0.1
    I want to understand what I am doing wrong in general because it happened at other projects and also specifically for this project that I am just starting and want to continue without starting it over.

    Thanks in advance,
    Daniel

    You have a class Chinese1 in a package chinese1 so the full name of the class is chinese1.Chinese1; and that's how you're supposed to run it:

    Java Code:
    java chinese1.Chinese1
    kind regards,

    Hi,

    I don't "run" anything, I just press the > button (or F6) in netbeans.
    I've also opened the command prompt to run what you told me and I still get the same error.

    What does F6 do? I thought F11 was clean and build in Netbeans?

    Happy New Year!!
    I am trying to run the Chinese1 class
    What I did so far is this:
    I've created a new project Chinese1
    Netbeans created the Chinese1.java file I posted here
    I also created another class for the GUI and opened it from the main without problems
    I then started to do what i saw here: Play mp3 using java.mp4 - YouTube
    to add mp3 playing abbility to the program
    then I've got the error I posted, even though i remarked the new code it didn't help to get the code running again
    The problem is that I get this kind of error on the simplest of programs sometimes
    I am trying to learn java with my son and it is really annoying that small code changes in a small program gets me this error and nothing I do can fix it.
    That is why also a general question because it is not the first time I get this error.
    Is there another java development platform for Windows that can I use to develop software with GUI like Netbeans?
    I've tryed Eclipse but the GUI development it is not "built in" like in Netbeans.
    I want also to develop to Android, after I got better in java.
