Question
Error: Main method not found in class Main, please define the main method as: public static void main(String[] args)or a JavaFX application class must extend javafx.application.Application
Solution
The error message you're seeing is common in Java when the program you're trying to run doesn't have a main method. The main method is the entry point for your application and looks like this:
public static void main(String[] args) {
// your code here
}
This method must be defined in your class for the Java Virtual Machine (JVM) to run your application. If it's not present, the JVM doesn't know where to start executing your code, hence the error.
To fix this, you need to add a main method to your class. Here's an example of what your code might look like:
public class Main {
public static void main(String[] args) {
// your code here
}
}
In this example, Main is the name of your class. You can replace it with whatever your class is actually called. The important part is the public static void main(String[] args) line. This defines the main method that the JVM is looking for.
