java数组输出最高分和姓名

java数组输出最高分和姓名

这个是做了排序,按从大到小,,,那么你取前两个就行了,,,,其他的方法也是硬代码死判断....那我再给你写个.

你把main替换下:

public static void _) {

Scanner in = new Scanner(System.in);

System.out.print("输入学生个数:");

int num = in.nextInt();

List data = new ArrayList();

for (int i = 0; i < num; i++) {

Bean bean = new Bean();

System.out.print("输入第" + (i + 1) + "个学生的姓名:");

String name = in.next();

System.out.print("输入第" + (i + 1) + "个学生的分数:");

double fen = in.nextDouble();

bean.setName(name);

bean.setFen(fen);

data.add(bean);

}

double max0 = Double.MIN_VALUE;

double max1 = Double.MIN_VALUE;

for (int i = 0; i < data.size(); i++) {

Bean bean = (Bean) (i);

max0 = Math.Fen(), max0);

}

for (int i = 0; i < data.size(); i++) {

Bean bean = (Bean) (i);

if (max0 != Fen()) {

max1 = Math.Fen(), max1);

}

}

System.out.println("最高分:" + max0);

System.out.println("二高分:" + max1);

}
