java制作五环代码 java 环形数组

用java写奥运五环。

设奥运5环为5个对象:A,B,C,D,E

创新互联公司网站建设由有经验的网站设计师、开发人员和项目经理组成的专业建站团队,负责网站视觉设计、用户体验优化、交互设计和前端开发等方面的工作,以确保网站外观精美、成都网站制作、成都网站设计易于使用并且具有良好的响应性。

则java程序如下:

ListInteger a=new ArrayListInteger(9);

ListInteger b=new ArrayListInteger();

ListInteger c=new ArrayListInteger();

ListInteger d=new ArrayListInteger();

ListInteger e=new ArrayListInteger();

ListInteger reslist =Arrays.asList(new Integer[] {1,2,3,4});

ListInteger res1list =Arrays.asList(new Integer[] {8,7,6,5});

b.add(reslist.get(0)).add(res1list.get(0));

c.add(reslist.get(1)).add(res1list.get(1));

d.add(reslist.get(2)).add(res1list.get(2));

e.add(reslist.get(3)).add(res1list.get(3));

java怎么绘制五环图案?

五环图片,其关键点是确定五个圆的中心点,只要确定了中心点,画圆就简单了,这个需要你计算了,可以先用笔在纸上画一画,想想思路,祝你成功

求计算机高人,要求JAVA的。。谢谢了! 绘图的题目不用了
