Thanks
here is my code:
import javax.swing.JPanel;
import java.util.Random;
import java.awt.*;
public class NervousShapesPanel extends JPanel{
Shape[] shapes;
Random r;
int width, height;
public NervousShapesPanel(){
shapes = new Shape[50];
r = new Random();
height = 200;
width = 200;
setPreferredSize(new Dimension(width, height));
}
public void paintComponent(Graphics g){
int shape = r.nextInt(2);
int radius = r.nextInt(11) + 10;
int w = r.nextInt(11) + 10;
int h = r.nextInt(11) + 10;
int cX = r.nextInt(width-radius);
int cY = r.nextInt(height-radius);
int rX = r.nextInt(width-w);
int rY = r.nextInt(height-h);
Color c = new Color(r.nextInt(256), r.nextInt(256), r.nextInt(256));
//initialize the shape
for(int i = 0; i < shapes.length; i++){
shapes[i] = (shape == 0) ? new Circle(cX, cY, c, radius) : new Rectangle(rX, rY, c, h, w);
shapes[i].draw(g);
}
}
}
the shape class, as well as it's subclasses Circle and Rectangle were made by me. They both extend Shape, so they're both exactly similar except that circle has a radius variable, and rectangle has a width and height variable. Because they're nearly identical, I'll just show you circle:
import java.awt.*;
public class Circle extends Shape{
private int radius;
public Circle(int x, int y, Color color, int radius){
super(x, y, color);
this.radius=radius;
}
@Override
public int getHeight() {
return radius;
}
@Override
public int getWidth() {
return radius;
}
@Override
public void draw(Graphics g) {
g.setColor(color);
g.fillOval(x, y, radius, radius);
}
}
thanks in advance!
