Thread: Hello!

I think your code is almost right. However, I think you need JFrame in order to have graphics on the screen. Notice ColorPanel uses Graphics in order to draw string on the screen. In Main class, I have created an instance of JFrame and ColorPanel. Since the constructor of ColorPanel takes a color argument, I passed Color.BLACK. Finally, I've added that to the frame. Hope this helps. Let me know your comments


Main.java

import javax.swing.*;
import java.awt.*;
 
public class Main {
    public static void main(String[] args) {
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        ColorPanel p = new ColorPanel(Color.BLACK);
        f.add(p);
        f.setSize(400, 250);
        f.setVisible(true);
    }
}

ColorPanel.java

import java.awt.*;
import javax.swing.*;
 
public class ColorPanel extends JPanel {
    public ColorPanel(Color backColor) {
        setBackground(backColor);
    }
    public void paintComponent(Graphics g) {
        super.paintComponent(g);
 
        g.setColor(Color.BLUE);
        g.drawString("hello", 100, 45);
    }
}
