***I am getting an error message saying ...Error: Main method not found in class sullivan4.Sullivan4_2, please define the main method as:
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application *********
*****What is wrong with my code ?
![### Error Message in Java Console
**Error Message:**
```
Error: Main method not found in class sullivan4.Sullivan4_2, please define the main method as:
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application
```
**Explanation:**
This error message indicates that the Java Virtual Machine (JVM) could not find the `main` method in the specified class `sullivan4.Sullivan4_2`. In Java applications, the `main` method serves as the entry point of the application. It must be defined exactly as `public static void main(String[] args)` for a standard Java program.
Alternatively, if this is meant to be a JavaFX application, the class should extend `javafx.application.Application`.
**Steps to Resolve:**
1. **Define the Main Method:**
- If you're creating a console-based application, make sure the `main` method is correctly defined in your class:
```java
public static void main(String[] args) {
// Your code here
}
```
2. **JavaFX Application:**
- If this is a JavaFX application, ensure your class extends `javafx.application.Application` and includes the `start` method:
```java
import javafx.application.Application;
import javafx.stage.Stage;
public class Sullivan4_2 extends Application {
@Override
public void start(Stage primaryStage) {
// Your code here
}
public static void main(String[] args) {
launch(args);
}
}
```
Make the necessary changes to your class based on the type of application you intend to create. If this error persists, verify your classpath and confirm that you are running the correct Java file.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc317763d-1fa7-4bbf-8337-a2804d7c778b%2F95abea03-411f-4acb-9df4-d45a349941f2%2F9o9ikp_processed.png&w=3840&q=75)
