Java GUI for red, green, blue button ... some syntax error I cannot fix. please helps. there are 2 classes thanks.

// this program demonstrates to create the frame and shows the color in circle

// whenever the red or green or blue color button is clicked.

// File: CircleIcon.java

import java.awt.*;

import java.awt.geom.*;

import javax.swing.*;

// class definition that implements the Icon interface

public class CircleIcon implements Icon{

// declare the private variables

private int size;

private Color color;

// parameterized constructor

public CircleIcon(int aSize, Color color){

// assign the size

size = aSize;

// assign the color

this.color = color;

}

// the setColor() method accepts "color" as an input parameter to set the color for icon

public void setColor(Color color){

// set the icon color

this.color = color;

}

public int getIconWidth(){

// return the size of icon

return size;

}

// this method is implemented from Icon interface to set height for icon

public int getIconHeight(){

// return the size of icon

return size;

}

// this method is implemented from Icon interface to draw and fill the color for circle

public void paintIcon(Component c, Graphics g, int x, int y){

// define "g2" object from Graphics2D class

Graphics2D g2 = (Graphics2D)g;

// ellipse shape to draw the circle image

Ellipse2D.Double planet = new Ellipse2D.Double(x, y, size, size);

// set the color for circle image

g2.setColor(color);

// fill the color for circle image

g2.fill(planet);

}

}
