Question is about the object cont in mainWindow, I cant use it!
I got a Package (View) containing mainWindow and main. In my main I got the code:
package View;
import java.awt.EventQueue;
import Controller.mainController;
public class main {
public static void main(String args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
mainWindow view = new mainWindow();
mainController cont = new mainController(view);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
in my mainWindow, I got:
public class mainWindow {
public mainWindow() {
initialize();
}
public void initialize() {
frame = new JFrame();
frame.getContentPane().setBackground(SystemColor.control);
frame.setBounds(100, 100, 728, 450);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
JButton ButtonStartGame = new JButton("Start Game");
ButtonStartGame.setToolTipText("Start the game");
ButtonStartGame.setEnabled(false);
ButtonStartGame.setBounds(12, 189, 117, 25);
frame.getContentPane().add(ButtonStartGame);
ButtonStartGame.addActionListener(e->cont.StartGame());
frame.setVisible(true);
}
}

What do you try to achieve withButtonStartGame.addActionListener(e->cont.StartGame())?

BTW, please check your naming. Class names start with an uppercase character. Variables, members, etc. start with a lowercase

Question is, why cant I use the object cont in mainWindow, the object is created in main(String args). StartGame() is a function in mainController class, the function just prints out "hello". The error I get is "Exception in thread "main" java.lang.Error: Unresolved compilation problems: cont cannot be resolved"

First of all,e->cont.StartGame()is not a valid java syntax.
