Editor does not contain a main type eclipse ошибка

Just going through the sample Scala code on Scala website, but encountered an annoying error when trying to run it.

Here’s the code: http://www.scala-lang.org/node/45. On running it on Eclipse, I got this message ‘Editor does not contain a main type’ that prevents it from running.

Is there anything I need to do…i.e break that file into multiple files, or what?

In Eclipse, make sure you add your source folder in the project properties -> java build path -> source. Otherwise, the main() function may not be included in your project.

I have this problem a lot with Eclipse and Scala. It helps if you clean your workspace and rebuild your Project.

Sometimes Eclipse doesn’t recognize correctly which files it has to recompile

Edit:
The Code runs fine in Eclipse

You have to make sure that your .java files are in the .src folder in eclipse. I had the same exact problem until I got it figured out.

Just make sure that the folder you work in is added to the built path:

right-click your folder —> build Path —> Use as source Folder

and it should now find main therein.

I had the same problem. I tried all sorts of things. And I came to know that

My .java files were not linked and
they were not placed in the ‘src’ folder.

Things I did:

Project properties >> Java Build Path >> Source

Deleted the original ‘src’ folder which was empty using ‘Remove’ option
Added the source that contained my source .java files using the ‘Add Folder’ option

This solved the error.

What you should do is, create a Java Project, but make sure you put this file in the package file of that project, otherwise you’ll encounter same error.

That code is valid. Have you tried to compile it by hand using scalac? Also, have you called your file «addressbook», all lowercase, like the name of the object?

Also, I found that Eclipse, for some reason, set the main class to be «.addressbook» instead of «addressbook».

under that will find src folder their you right click select —>class option

Make sure that your .java file is present either in the str package, or in some other package. If the java file with the main function is outside all packages, this error is thrown.

answered Jul 1, 2014 at 8:46

Have faced the similar issue, resolved this by right clicking on the main method in the outline view and run as Java application.

answered Nov 10, 2017 at 6:27

I just had this problem too. The solution is to make sure eclipse created the project as Java project. Just create a new Java project and copy your class into the src folder (and import the eventual dependencies). This should fix the problem.

The correct answer is: the Scala library needs to before the JRE library in the buildpath.

Go to Java Buildpath > Order and Export and move Scala library to the top

I had this problem with a Java project that I imported from the file system (under Eclipse Helios). Here’s a hint: the src code didn’t seem to be compiled at all, as no «bin» directory showed up.

I had to create a Java project from scratch (using the wizard), then compare the .project files of the non-working and working projects.

The project giving «Editor does not contain a main type» had this as the «buildSpec» in the .project file:

<buildSpec>
</buildSpec>

But the working project had this as the «buildSpec»:

<buildSpec>
    <buildCommand>
        <name>org.eclipse.jdt.core.javabuilder</name>
        <arguments>
        </arguments>
    </buildCommand>
</buildSpec>

I copied this in, and the imported project worked.

I know my answer is for Java, but the same might be the issue for your Scala project.

answered Mar 12, 2014 at 0:28

May be the file you have created is outside the src(source) folder. Trying to call the class object(from the file located in the src folder) from the .java file outside the source folder results in the same error. Copy .java file to the source folder, then build it. The error will be gone.

This could be the issue with the Java Build path.
Try below steps :

Go to project properties
Go to java Build Path
Go to Source tab and add project’s src folder

This should resolve the issue.

For me, in Eclipse 3.6, this problem occurs when my main method is not public. I caused the problem by having a main method like this:

static void main(String[] args)

The dubugger was unable to detect this by itself. I am pretty suprised Eclipse overlooked this.

In the worst case — create the project once again with all the imports from the beginning. In my case none of the other options worked. This type of error hints that there is an error in the project settings. I once managed to solve it, but once further developments were done, the error came back. Recreating everything from the beginning helped me understand and optimize some links, and now I am confident it works correctly.

One more thing to check: make sure that your source file contains the correct package declaration corresponding to the subdirectory it’s in. The error mentioned by the OP can be seen when trying to run a «main type» declared in a file in a subdirectory but missing the package statement.

I have this problem too after I changed the source folder. The solution that worked for is just editing the file and save it.

In my particular ‘Hello World’ case the cause for this problem was the fact, that my main() method was inside the Scala class.

I put the main() method under the Scala object and the error disappeared.

That is because Scala object in Java terms is the entity with only static members and methods inside.

That is why Java’s public static void main() in Scala must be placed under object.

(Scala class may not contain static’s inside)

So in this tutorial, We will know that what kind of reasons can be for getting this error “Editor does not contain a main type” and we will see how to fix this error.

Basically, this type of Error means your Editor is not able to find the “main” method in any of your current program classes. The editor shows this error because when you want to run the project, at that time, the interpreter couldn’t find the main function to start the execution of the program.

Reasons for Error

So there can be various reasons causing this error:

If you have not declared the main method in your program, at that time it will be compiled successfully but while running the program, it will throw this error.
It can occur if the .java file has not linked or has not placed in the src
If you have not added a build path in the same folder where you are working.
If .class file or project file is not present in your workspace at that time it will occur.
If you are using Eclipse for java Programming and you have not declared the main method as public.
If the program is not compiled correctly.

Solutions

First, you should check that you have declared the “main” method in your program or not if you have not then you should write the “main” method inside your class.
If you are using eclipse and you have declared the “main” method in your program and you have written it inside the class then you have to check that you have added the build path or not. If you have not added then:- go to project properties -> Choose java build path -> Click on the source.
If the editor is not able to find the Source folder then you have to follow these steps:-

1. Right-click on Project folder and go through the Properties
2. Choose ‘Java Build Path’.
3. Click on the ‘Sources’ tab on top.
4. Click on ‘Add Folder’ on the right panel.
5. Select your folders and apply them.

If you have not to clean your project then you should try this, Project -> Clean, or you can follow these steps on the command line -> run “eclipse -clean -refresh.
In the last, confirm that you have declared the main method with “public” access specifier, like ->

public static void main(String[] args)

{

//body

}

And if you are sure about this that you have written the main method and code correctly then delete the current program file after copying your code and create a new file and paste in it.
Please Check that .class file is present in your workspace or not, If there is not present that file then you should add that file by compiling it before running the Project.
Wherever you have written the “main” method, you should sure about this that It is present inside the src folder, if It’s not then you have to place the “main” method inside the src folder and after that, you could simply run the Program.
If the program is not compiled correctly that time project does not contain an executable main class, So that time you have to compile the program correctly.

That was all about the reasons and solutions to this “Editor does not contain a main type”. If you have any queries or suggestions please leave in the comment below. We would love to help.

Я загрузил eclipse-jee-kepler-SR1-linux-gtk-x86_64.tar.gz. Это затмение встроено с java, а мой Lubuntu — 64-битный. Всякий раз, когда я компилирую и запускаю простой код в java, как показано ниже:

public class Sample{

   public static void main(String[] args){
       System.out.println("YOLO");
   }
}

Я всегда получаю Editor does not contain a main type.
Я помещаю файл в папку проекта с именем Sample. Это затмение должно скомпилировать java-код, потому что его дистрибутив IDE специализируется на java.

Как я могу решить эту ошибку?

У меня была такая же проблема. Это будет звучать безумно, но если кто-то увидит это, попробуйте это до решительных мер. удалить подпись метода:

public static void main(String args[])

(Не является телом объявления основного простого метода)

Сохраните проект, а затем повторно напишите заголовок метода обратно на его соответствующий корпус. Сохраните снова и снова запустите. Это сработало для меня, но если он не работает, попробуйте еще раз, но очистите проект прямо перед повторным запуском.

Я не знаю, как это исправлено, но это произошло. Стоит ли задуматься, прежде чем воссоздать весь проект?

В идеале исходный код должен находиться в пакете src/default, даже если вы не указали имя пакета. По какой-то причине исходный файл может находиться вне папки src. Создайте в папке scr, он будет работать!

The problem statement “editor does not contain a main type” is usually encountered while coding on java. The error is encountered on the IDE Eclipse. Eclipse is an environment (IDE) used for writing programs in different languages. It mostly exists for writing programs in Java but can also be utilized for different languages such as c/c++ or even JavaScript with the help of extensions.

This article will provide guidance on why the “editor does not contain a main type” problem occurs while trying to run code in Eclipse. We will also find out what to do to fix these issues can be fixed.

Resolve issue statement “editor does not contain a main type”

There exist various reasons that can invoke the error. A few of the major reasons are elaborated on in this section.

Reason 1: Absence of the main method

The most obvious reason for this problem is that your code is missing the main function in the syntax of your existing class. This is the main function which is absent:

public static void main(String[]args)

Solution: Add the main method

The solution for the above-stated reason is quite straightforward. We simply need to implement the main function into our java class.

Below is an example of how we can implement the main function:

Reason 2: Build path

Another reason for this error revolves around the build path. When the build path is not set to the correct location where your java project exists, it can cause the “editor does not contain a main type” error. Usually, we want the build path to be set to the “src” folder. The “src” folder is the main source folder that is created alongside the project. It contains the program files and acts as the default build path.

Solution: Check the build path

The solution to the second reason is to fix the build path of your project. Follow these steps to fix your build path:

Step 1: Remove the build path

Expand your project file and right-click on the “src” folder. Here, you will find the “Build Path”, click on it and then navigate to the “Remove from Build Path”.

Step 2: Set the build path

After removing it, click on the “Build Path” again where you will find the option “Use as Source Folder”.

Reason 3: Check the build path of your Java package

Reason 3 is that the file that we want to run is not present in our src folder. The Java file we want to execute lies inside the “javatest” package and our build path is currently set to this package as can be seen in the following image.

Solution: Add Java package to src folder

To add your Java package back to the “src” directory:

Right click on the package and ‘hover the mouse on the “Build path” option.
Click on the “Remove from Build Path”

By doing so, your package will be moved to the “src” directory as shown below:

Conclusion

There are 3 major reasons that can cause the issue “editor does not contain a main type”. One is the missing main function which we learned to add to the java class. Another is the build path is not correctly set. This error can be fixed by refreshing the build path or checking the build path of your package file (where the java file is located). Here, you have learned multiple solutions to avoid the problem “editor does not contain a main type”.

Источник

Solution 1

Did you import the packages for the file reading stuff.

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.InputStreamReader;

also here

cfiltering(numberOfUsers, numberOfMovies);

Are you trying to create an object or calling a method?

also another thing:

user_movie_matrix[userNo][movieNo]=rating;

you are assigning a value to a member of an instance as if it was a static variable
also remove the Th in

private int user_movie_matrix[][];Th

Hope this helps.

Solution 2

private int user_movie_matrix[][];Th. should be `private int user_movie_matrix[][];.

private int user_movie_matrix[][]; should be private static int user_movie_matrix[][];

cfiltering(numberOfUsers, numberOfMovies); should be new cfiltering(numberOfUsers, numberOfMovies);

Whether or not the code works as intended after these changes is beyond the scope of this answer; there were several syntax/scoping errors.

Comments

I can’t seem to run the following code in Eclipse. I do have a main method and this is the currently opened file. I even tried the «Run As» option but I keep getting this error: «editor does not contain a main type». What am I doing wrong here?

    //remember this is just a reference
    //this is a 2d matrix i.e. user*movie
    private static int user_movie_matrix[][];

    //remember this is just a reference
    //this is a 2d matrix i.e. user*user and contains
    //the similarity score for every pair of users.
    private float user_user_matrix[][]; 


    public cfiltering()
    {
        //this is default constructor, which just creates the following:
        //ofcourse you need to overload the constructor so that it takes in the dimensions

        //this is 2d matrix of size 1*1
        user_movie_matrix=new int[1][1];
        //this is 2d matrix of size 1*1
        user_user_matrix=new float[1][1];
    }

    public cfiltering(int height, int width)
    {
        user_movie_matrix=new int[height][width];
        user_user_matrix=new float[height][height];
    }


    public static void main(String[] args) {
        //1.0 this is where you open/read file
        //2.0 read dimensions of number of users and number of movies
        //3.0 create a 2d matrix i.e. user_movie_matrix with the above dimensions. 
        //4.0 you are welcome to overload constructors i.e. create new ones. 
        //5.0 create a function called calculate_similarity_score 
        //you are free to define the signature of the function
        //The above function calculates similarity score for every pair of users
        //6.0 create a new function that prints out the contents of user_user_matrix 

        try
        {
            //fileinputstream just reads in raw bytes. 
            FileInputStream fstream = new FileInputStream("inputfile.txt");

            //because fstream is just bytes, and what we really need is characters, we need
            //to convert the bytes into characters. This is done by InputStreamReader. 
            BufferedReader br = new BufferedReader(new InputStreamReader(fstream));
            int numberOfUsers=Integer.parseInt(br.readLine());
            int numberOfMovies=Integer.parseInt(br.readLine());

            //Now you have numberOfUsers and numberOfMovies to create your first object. 
            //this object will initialize the user_movie_matrix and user_user_matrix.

            new cfiltering(numberOfUsers, numberOfMovies);

            //this is a blankline being read
            br.readLine();

                for (String singleRating:allRatings)
                {
                    int rating=Integer.parseInt(singleRating);
                    //now you can start populating your user_movie_matrix
                    System.out.println(rating);
                    user_movie_matrix[userNo][movieNo]=rating;
                    ++ movieNo;
                }

        }
        catch(Exception e)
        {
            System.out.print(e.getMessage());
        }
    }

}

I’m trying to call the method that changes the dimensions of «user_movie_matrix» and «user_user_matrix»
I did not intend for user_movie_matrix to be a static variable. Does it have to be static for it to work properly?
It must be static as the code is written, because you directly access it from a static method, namely public static void main(String[] args).
oh i see…so what u should do is
oh i see…so what u should do is create a class method like’set_user_movie_matrix(x,y) {this.userNo = x; this.movieNo = y;}’` to change those values of an object …then instead of creating an object without a name do ‘cfiltering variable_name = new cfiltering(numberOfUsers, numberOfMovies);` and then using that variable call the methods like `variable_name.set_user_movie_matrix(userNo,movieNo)’
