If you are encountering the error "Editor does not contain a main type" in Eclipse IDE Java, it means that Eclipse is not able to identify the main method of your Java application. This error usually occurs when the Java class that you are trying to run does not have a proper main method or if the file containing the main method is not configured correctly in Eclipse.

Here are some steps that you can follow to fix this error:

Check if your Java file has a proper main method. The main method should have the signature "public static void main(String[] args)".
Make sure that the Java file containing the main method is selected as the "main" class in the Run Configuration. To do this, right-click on the Java file in the Package Explorer and select "Run As" - "Java Application". This should open the Run Configuration window. Make sure that the "Main class" field contains the correct class name.
If the "Main class" field is blank or contains an incorrect class name, you can browse and select the correct class by clicking on the "Search" button next to the field.
If you have recently made changes to your project or code, try cleaning and rebuilding your project. To do this, go to "Project" - "Clean" and select your project. Then click on "OK" to clean the project. After cleaning the project, rebuild it by clicking on "Project" - "Build Project".
If none of the above steps work, try restarting Eclipse and see if the error persists.
These steps should help you fix the "Editor does not contain a main type" error in Eclipse IDE Java.
