graphics won't work

[HelloWorld1234]

I followed a youtuber called TheNewBoston.
The problem is that it just gives me a greyish screen, and I have no idea what the problem is...
here is the code I used.

class Main(the main class!)

package gui.basicGraphic;

import javax.swing.*;

public class Main {
	public static void main(String[] args) {
		
		JFrame f = new JFrame("the title");
		f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		DrawGraphic dg = new DrawGraphic();
		f.add(dg);
		f.setSize(400, 250);
		f.setVisible(true);
	}
}

and my second class.

class DrawGraphic(the class with the graphics stuff!)

package gui.basicGraphic;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class DrawGraphic extends JPanel{
	
	public void PaintComponent(Graphics g){
		super.paintComponents(g);
		this.setBackground(Color.WHITE);
		
		g.setColor(Color.BLUE);
		g.fillRect(25, 25, 100, 30);
		
		g.setColor(new Color(190,81,215));
		g.fillRect(25, 65, 100, 30);
		
		g.setColor(Color.RED);
		g.drawString("this is some tecxt", 25, 120);
	}
}

I hope someone know a solution to this :): cause I want to make GUI stuff, but if it doesn't work I have to do something else... :/

Java is case sensitive - check the case of your methods...the @Override annotation helps you verify you have not misspelled a method you are intending to override

@Override
public void PaintComponent(Graphics g){//compile time error
...
}

it just tells me that the @Override has to go away, and it didn't fix anything.

The method 'paintComponent' is with a lower case 'p'.

Thanks that worked!

[JosAH]

Thanks that worked!

Hold on for a second: that was the reason your compiler protested at the @Override annotation because PaintComponent( ... ) didn't override paintComponent( ... ); see why it is a handy tool?

kind regards,

Yeah, I see now.
