Question

编写一个程序，提示用户输入学生人数以及每个学生的姓名和分数，最后显示得分最高的学生。

我坚持如何显示他们的名字？

这是我的代码：

package Exercises;
import java.util.Scanner;
public class Page93 
{

    public static void main(String[] args) 
    {
        String name = null;
        int count;
        double score = 0;
        double highest = 0;

        Scanner input = new Scanner (System.in);

        System.out.print("Enter the number of student : ");
        int numberofstudent = input.nextInt();

        for (count=0; count<numberofstudent; count++)
        {
            System.out.print("\nStudent name : ");
            name = input.next().toUpperCase();
            System.out.print("Score        : ");
            score = input.nextInt();

            if (highest<score)
                highest=score;
        }
        System.out.print("\nThe highest score : " + highest );
    }
}

Answer 1

定义变量 studentWithHighestScore 以存储得分最高的学生。每当您更新最高时，都要更新此变量。

   if (highest<score) {
      highest=score;
      studentWithHighestScore = name
   }

package Exercises;
import java.util.Scanner;
public class Page93 
{


   public static void main(String[] args) 
    {
        String name = null;
        int count;
        double score = 0;
        double highest = 0;
        String highestName;

        Scanner input = new Scanner (System.in);

        System.out.print("Enter the number of student : ");
        int numberofstudent = input.nextInt();

        for (count=0; count<numberofstudent; count++)
        {
            System.out.print("\nStudent name : ");
            name = input.next().toUpperCase();
            System.out.print("Score        : ");
            score = input.nextInt();

            if (highest<score)
            {
              highest=score;
              highestName = name;
            }
        }
        System.out.print("\nThe highest student : " + highestName + " score : " + highest );
    }
}

        Student stu = new Student();
        Student max = new Student();
        Student min = new Student("","",  0);
        String [] arr1=new String [n];
        String [] arr2=new String [n];
        int [] arr3=new int [n];

}
        System.out.println("name, ID of the highest score and the second highest score:");
System.out.println(max.name + " " + max.stu_id);
System.out.println(min.name + " " + min.stu_id);
        in.close();
    }
}
