java 画图板程序

java画图程序找一个java 程序:画图程序包括画圆，谁有简单的？importjava. awt . *；importjava. awt . event . *；importjava. util . *；importjavax . swing . *；importjava. awt . geom . *；importjava. io . *；classpointimplementsselizable { intx。

importjava. applet . *；importjava. awt . *；importjava. awt . event . *；importjava. util . *；importjavax . swing . *；importjava. awt . geom . *；importjava. io . *；classpointimplementsselizable { intx，

inty，Colorcol，inttool，int board){ this . xx；this.yythis.colcolthis.tooltool这个。寄宿生；} } classpaintboardextendsFrameimplementsActionListener，MouseMotionListener，

我对楼上的代码做了一点修正，我觉得现在可以正常运行了://# 8.15/# {intx，x1，y1，x2，y2，width，heightbooleanisFirstPointtrue//行intdrawTypePaintingGround。初始化开始时绘制线条；//初始化开始不是为了填充booleanisFillfalse//添加控件buttongroupbtnegnewbuttongroup()；ButtonbtLinenewButton(line)；ButtonbtRectanglenewButton(矩形)；ButtonbtRoundnewButton(圆形)；ButtonbtEllipsenewButton(椭圆)；ButtontbFillStatenewButton(填充)；Buttonbutton3newButton(文本操作)；Buttonbutton2newButton(清除)；Buttonbutton1newButton(选择颜色)；PanelbuttonPanelnewPa .

This 程序又画了两个图形，但是你想要的在上面。保留图形的要求与“repaint()”importjava. awt . *有关；importjava. awt . event . *；importjava. applet . *；publicsclassdrawgraphicsdemoextendespeletimplementsactionlistener { int flag 0；PanelpnewPanel()；ButtonlinenewButton(交叉)；ButtonovalnewButton(圆形)；ButtonrectnewButton(画一个矩形)；ButtonpolygonnewButtonButtonarcnewButton(画一个扇形)；int xpoints/////保存一个pb。java file并直接编译执行Importjava. applet .
