الرسم بالجافا

ممكن اساعدك بكود مشابه انت استفيد منه واكتب الكود اللي بلزمك

الكود يقوم برسم دوائر بأحجام مختلفة كل ما اضغط الزر واحدد الحجم يظهر الحجم المطلوب

جرب اعمله run عنك وشوفه بس انتبه لأسم الpackage لما تعمل copy and paste

package bestbetter;

import java.awt.*;
import java.applet.*;
import java.awt.event.*; // 1.1
public class Applet1 extends Applet
                        implements ActionListener
{
  CheckboxGroup cbg = new CheckboxGroup();

  Checkbox good = new Checkbox("Good", false, cbg);
  Checkbox better = new Checkbox("Better", false, cbg);
  Checkbox best = new Checkbox("Best", true, cbg);

  Button paintIt = new Button("Paint It");

  public void init()
  {
    setLayout(new BorderLayout());
    add("North", makeButtons());
    add("South", paintIt);
    paintIt.addActionListener(this);
  }

  public void actionPerformed(ActionEvent ae)
  {
    Graphics g = getGraphics();

    int w = getSize().width;
    int h = getSize().height;
    int ratio = 1;

    Checkbox current = cbg.getSelectedCheckbox();
    if      (current == good)   ratio = 5;
    else if (current == better) ratio = 3;
    else if (current == best)   ratio = 2;

    g.clearRect(0, 0, w, h);
    g.fillOval(w/2 - ((w/ratio)/2),
               h/2 - ((h/ratio)/2),
               w/ratio, h/ratio);

  g.dispose();
  }

  public Panel makeButtons()
  {
    Panel p = new Panel();
    p.setLayout(new GridLayout(1, 0, 5, 5));
    p.add(good);
    p.add(better);
    p.add(best);

    Panel p2 = new Panel();
    p2.add(p);
    return p2;
  }
}
