Java Graphics: Drawing one object into another

I'm a beginner in java programming and I would appreciate if someone can guide me as to how I've to proceed to obtain the wanted solution I am looking for. Ive attached screenshots of the outputs that I obtain from running the code. the threebythree.java code creates a 3x3 square grid and the rhombus.java creates a rhombus. What I'm trying to attain is to take the whole rhombus drawing and paste it into each square present in the grid. I have attached an image showing the required rough output that Im looking for. I will be really greatful if someone could guide me in the right direction.

threebythree.java

Code :

---

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
public class threebythree extends JPanel {
 
	int s = 150;
 
	public threebythree(){
 
		setPreferredSize(new Dimension(450, 450));
		setBackground(Color.WHITE);
 
	}
 
	public void paintComponent(Graphics g){
		super.paintComponent(g);
		Graphics2D g2d=(Graphics2D)g;
		g2d.translate(60, 50);
 
 
		this.setBackground(Color.WHITE);
 
		for(int x=0; x<3; x++ ){
			for(int y=0; y<3; y++){
				g2d.drawRect(x*s, y*s, s, s);
 
			}			
		}		
	}	
}

rhombus.java

Code :

---

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
	public class rhombus extends JPanel {
 
		public rhombus(){
			JPanel jp2 = new JPanel();
			setPreferredSize(new Dimension(450, 450));
			setBackground(Color.WHITE);
 
		}
 
 
 
		public void paintComponent(Graphics g){
			super.paintComponent(g);
 
 
			Graphics2D g2d=(Graphics2D)g;
			int s = 100;
 
			this.setBackground(Color.WHITE);
			g2d.translate(275, 75);
			g2d.rotate(Math.toRadians(45));
			for(int x=0; x<3; x++ ){
				for(int y=0; y<3; y++){
					g2d.drawRect(x*s, y*s, s, s);	
 
				}			
			}		
		}	
	}

testing.java

Code :

---

import java.awt.*;
 
import javax.swing.*;
 
public class zaax {
	public static void main(String[] args){
 
		JFrame f = new JFrame("Testing");
		f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
 
		f.getContentPane().add(new rhombus());
		f.setSize(600, 600);
		f.setVisible(true);
 
 
 
 
	}
}

Well, how would you do this by hand? Get a piece of graph paper, and do the drawing, keeping track of the coordinates where you're drawing. Do you see a pattern?

I can manually draw the rhombus into the 3x3 square grid, that is definitely one solution but what I want do is to call the drawing of rhombus into the 3x3 square grid that I have created in another class. I hope you get what I mean.

Hmm, I'm not sure. What I'd do if I were you is create a method that draws a single square/rhombus at a specified coordinate, something like:

Code java:

---

public void drawSquare(int x, int y, Graphics){
//draw a single square with a rhombus inside it
}

---

Then just call that with whatever x and y value you want, in your loop. You could also add parameters for the width and height of the square.

Thank you very much!

No problem. Did you get it sorted out then?
