for this java program i am suppose to do the figure on the top left and put it in rows and columns shown in the figure underneath, but I am having trouble figuring out how to center the circles in the figure at the bottom. If you could help me figure out what is wrong with my code that would be great.

Step 1

Note: Modified Code highlighted in bold.

Code:

import java. awt.*;

public class DrawingTest

{

public static void main(String[] args) {

DrawingPanel panel= new DrawingPanel(480, 480);

Graphics g = panel.getGraphics();

panel.setBackground(Color.cyan);

draw(g);

drawSubFigure1(g);

}

public static void draw(Graphics g) {

g.setColor(Color.BLACK);

g.drawRect(0,0,100,100);

g.setColor(Color.GREEN);

g.fillRect(0,0,100,100);

g.setColor(Color.BLACK);

g.drawOval(0,0,100,100);

g.setColor(Color. YELLOW);

g.fillOval(0,0,100,100);

for(int i=0;i<6;i++){

g.setColor(Color.BLACK) ;

g.drawOval(0 + 10 * i, 0 + 10 *i, 100 - 20 * i, 100 - 20 * i);

}

g.setColor(Color.BLACK);

g.drawLine(0, 50, 100, 50);

g.drawLine(0, 0, 100, 100);

g.drawLine(0,100, 100, 0);

}

public static void drawSubFigure1(Graphics g) {

int x=10;

int y=120;

int size = 24;

for(int i=0;i<5;i++){

for(int j=0;j<5;j++){

g.setColor(Color.BLACK);

g.drawRect(x + 25 * i, y + 25 *j, size, size );

g.setColor(Color.GREEN);

g.drawRect(x + 25 * i, y + 25 *j, size, size );

g.setColor(Color.BLACK);

g.drawOval(x + 25 * i, y + 25 *j, size, size );

g.setColor(Color.YELLOW);

g.drawOval(x + 25 * i, y + 25 *j, size, size );

}

for( int i=0;i<5;i++){

for(int j=0;j<5;j++){

for(int k=0;k<5;k++){

g.setColor(Color.BLACK);

g.drawOval((x+25*i)+3*k,(y+25*j)+3*k,size-6*k,size-6*k);

}
