java制作五環(huán)代碼 java 環(huán)形數(shù)組
用java寫奧運(yùn)五環(huán)。
設(shè)奧運(yùn)5環(huán)為5個(gè)對(duì)象：A,B,C,D,E
創(chuàng)新互聯(lián)公司網(wǎng)站建設(shè)由有經(jīng)驗(yàn)的網(wǎng)站設(shè)計(jì)師、開發(fā)人員和項(xiàng)目經(jīng)理組成的專業(yè)建站團(tuán)隊(duì)，負(fù)責(zé)網(wǎng)站視覺設(shè)計(jì)、用戶體驗(yàn)優(yōu)化、交互設(shè)計(jì)和前端開發(fā)等方面的工作，以確保網(wǎng)站外觀精美、成都網(wǎng)站制作、成都網(wǎng)站設(shè)計(jì)易于使用并且具有良好的響應(yīng)性。
則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怎么繪制五環(huán)圖案？
五環(huán)圖片，其關(guān)鍵點(diǎn)是確定五個(gè)圓的中心點(diǎn)，只要確定了中心點(diǎn)，畫圓就簡(jiǎn)單了，這個(gè)需要你計(jì)算了，可以先用筆在紙上畫一畫，想想思路，祝你成功
求計(jì)算機(jī)高人，要求JAVA的。。謝謝了！ 繪圖的題目不用了
