    Default String won't display in my window

    I don't know what is causing this, but what happens, is that my window appears, but my drawString(); doesn't appear and show the text. No errors or anything.

    import java.awt.Graphics;
    import java.awt.Graphics2D;
     
    import javax.naming.ldap.Rdn;
     
     
    public class MainGameClass {
     
    	//Accesses the ScreenHandler class and makes it use 'sh' variable
    	static ScreenHandler sh = new ScreenHandler();
     
    	//Main thingy (duh)
     
    	public static void main(String[] args) {
     
    		//Makes ScreenHandler class activate DrawWindow method
    		sh.DrawWindow();
     
    	}
    	public void paint(Graphics g){
    		g.drawString("Hey!", 200, 200);
    	}
     
    }

    ScreenHandler class:

    import java.awt.BorderLayout;
    import java.awt.Color;
    import java.awt.Dimension;
    import java.awt.Font;
    import java.awt.Graphics;
    import java.awt.Graphics2D;
     
    import javax.swing.JFrame;
    import javax.swing.JLabel;
     
    //Referenced by MainGameClass
     
    public class ScreenHandler {
     
    	//Draws the window the game is in
    	JFrame frame = new JFrame("Indev v0.01");
     
    	public void DrawWindow(){
    		//Initiates window drawing
    		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     
    		JLabel emptyLabel = new JLabel("");
    		//Makes it 800 by 600
    		emptyLabel.setPreferredSize(new Dimension(1000, 600));
    		frame.getContentPane().add(emptyLabel, BorderLayout.CENTER);
     
    		frame.pack();
    		//Makes it visible
    		frame.setVisible(true);
     
    		//Activates the PaintWindow function below
    		PaintWindowColor();
     
    	}
    	public void PaintWindowColor(){
     
    		//Sets the background color to blue
    		//frame.getContentPane().setBackground(Color.BLUE);
    	}
     
    }

    The provided code is not enough for us to help you. We don't know what are you trying to do in ScreenHandling class.

    Add a println next to the drawString method call to verify that the paint method is being called.


    Where do you call the paint() method with the drawString?
    If you think you are overriding a component method add the annotation: @Override just before paint() to have the compiler tell you if you are.

    Please explain what you are trying to do. Neither of your classes extend any GUI classes.
    If you want to make drawings you are going to need some GUI.
    If you don't understand how to create a GUI application, try reading the tutorial:
    Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)
