机选福利彩票程序V2.0-批量插入，比V1.0效率高

阅读更多

今天上班没什么事情干，很无聊，于是拿出中午吃饭时买的彩票，开始研究，然后打开双色球走势图网页，感觉双色球的号码，就是一组随机数，无规律可循，靠的都是运气，于是想通过自己写的程序给自己选四组号码，看看能不能给自己带来好运！本程序按照双色球的出球顺序依次产生号码。并对产生的号码进行了排序展示
V1.0：

		LuckyNumber luckyNum=new LuckyNumber();
		/**

		for(int i=0;i<1;i++){
			System.out.println("-----------第"+(i+1)+"注----------");
			luckyNum.getLuckyNumber();	
		}

	public void getLuckyNumber(){
		Map luckyMap=new HashMap();

			    luckySb.append(luckyRed+" ");
			}
		}
		int luckyBlue=(int)(Math.random()*16+1);
		luckySb.append(luckyBlue);
