Thread: 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

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

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

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);
 
 
 
 
	}
}

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.

Thank you very much!
