Thread: Separate method to create Window

Hello!

Just wondering where I need to extend JFrame to get this working...

//imports
import javax.swing.JFrame;
 
//main class
public class mainClass extends JFrame {
	//class level variables
	private static final long serialVersionUID = 1L;
	double wX,wY,wW,wH;
	public static void main(String[] args) {
/*
 *  Main method calls and creates windows, sprite, etc.
 *  Separate methods will be made to manage the calls
 *  */
		createWindow(0,0,800,400,"Workbed");
	}
 
//create window method
	static void createWindow(double wX,double wY,double wW,double wH,String windowTitle){
		//window properties
		setTitle(windowTitle);
		setSize(wW,wH);
		setLocation(wX,wY);
		setVisible(true);
		setDefaultCloseOperation(EXIT_ON_CLOSE);
		//window arguments
	}

When I extend it from the mainClass, it comes up with errors in the createWindow method...


Thank you! Any other tips for this would be great!

You are actaly not creating a window. You extend the class with JFrame. I find this really annoying, i always import it and use it as a instance, wich makes you more capable of making more windows at once.
