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
