Error : Running array of objects in JavaFX with same method - javafx

Question

Here's the code :
Main File :
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package testobjectarray;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
/**
*
*
*/
public class TestObjectArray extends Application {
#Override
public void start(Stage primaryStage) {
Button btn = new Button();
btn.setText("Say 'Hello World'");
btn.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
System.out.println("Hello World!");
}
});
StackPane root = new StackPane();
root.getChildren().add(btn);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
/**
* The main() method is ignored in correctly deployed JavaFX application. main() serves only as fallback in case the application can not be launched through deployment artifacts, e.g., in IDEs
* with limited FX support. NetBeans ignores main().
*
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
myClass[] c = new myClass[5];
c[2].myMethod();
}
}
Class declared outside :
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package testobjectarray;
/**
*
*
*/
public class myClass {
public void myMethod(){
System.out.println("Inside myMethod");
}
}
Problem, I get errors when I compile i.e. initializing an array of objects and invoking the method. If I have just one object, it works great. Any help appreciated.

Answer 1

The problem with your code is you are initialising an array of size 5, but you never add values to it. Try the following code
myClass[] c = new myClass[5];
c[0] = new myClass();
c[1] = new myClass(); // and so on till c[4]
//now you can call the methods
c[1].myMethod();
