Thread: Code is giving an error in console, but there are no errors apparent in the code!

Basically, I am trying to drawString and I am getting some unexplained errors. Eclipse isn't redlining anything, but when I run the application, it gives an error and refuses to draw the test. Here is my source code:

MainGameClass:

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();
		sh.PaintWindowText(null);
 
	}
 
}

ScreenHandler

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);
	}
	public void PaintWindowText(Graphics g){
 
		if(g instanceof Graphics2D){
 
		}
		try{
		g.drawString("Did this work?", 200, 200);
		} catch (Exception ex)
		{
			ex.printStackTrace();
		}
		//Makes a new JLabel with text in it
		//JLabel label = new JLabel("Did this work?");
 
		//Sets the font to plain
		//label.setFont(new Font("Sans-Serif",Font.PLAIN,140));
 
		//Adds the text label to the screen
		//frame.add(label);
	}
}

I hope you can help, as any guidance would be greatly appreciated!
