Without seeing your code, it is difficult to determine the exact cause of the error. However, here are some common reasons why you might be getting an error in JavaFX or Swing:

  1. Missing imports: Make sure you have imported all the necessary classes and packages for JavaFX or Swing. For example, for JavaFX, you need to import javafx.application.Application and javafx.scene.*.

  2. Incorrect class or method names: Double-check that you have used the correct class or method names in your code. Typos or incorrect naming can lead to errors.

  3. Incorrect package structure: Ensure that your file structure and package declarations are correct. If your file is in a different package than expected, it may not be able to access the necessary classes.

  4. Incorrect event handling: If you are using event handling in your code, make sure you have implemented it correctly. For example, in JavaFX, make sure you have added event listeners to the appropriate nodes and implemented the corresponding methods.

  5. Missing required components: Check if you have added all the required components to your UI layout or scene graph. For example, if you are using a JFrame in Swing, make sure you have added all necessary buttons, labels, etc., to it.

  6. Incompatible versions: Ensure that you are using compatible versions of JavaFX/Swing libraries with your JDK version. Mismatched versions can cause errors.

  7. Runtime exceptions: Some errors may occur during runtime rather than compile-time. In such cases, carefully read the error message and stack trace to identify the cause of the issue.

If none of these suggestions help resolve your issue, please provide more details about the specific error message and share your code so that we can assist you further.

it says my gui file doesn't have a main method, but i have a main class in the same folder. it was working perfectly fine before

long sluice
#

start the class with the main method in it, that's your entry point

#

main.class is just a class, u need a main method to start a program

frank quiver
#

Yeah and I had a main method in a separate class called Main.java

#

it was working just fine and randomly started acting up

long sluice
#

swap your config then

i restarted netbeans and added a main class, and removed it. it started working again
