因此,每次我运行此问题时,它都会编译并运行,直到我输入第一个名称:

代码:

import java.util.Scanner;
public class BestStudent {

public static void main(String[] args) {
    // TODO Auto-generated method stub
    Scanner input= new Scanner(System.in);

    System.out.println("Enter the number of students:");
    int numStudents= input.nextInt();

    String highName=" ";
    double highScore=0.0;
    int i;

    for(i=1;i<numStudents+1;i++){
        System.out.println("Student "+i+" of "+numStudents);
        System.out.println("Enter the student's name:");
        String name=input.nextLine();

        System.out.println("Enter students score:");
        double score=input.nextDouble();

        if(score>highScore) {
            highScore=score;
            highName=name;
            }
    }

    System.out.println("The highest score was "+highScore+" and "+highName+" got it");
}

}

这是我得到的错误:

Exception in thread "main" java.util.InputMismatchException
at java.util.Scanner.throwFor(Unknown Source)
at java.util.Scanner.next(Unknown Source)
at java.util.Scanner.nextDouble(Unknown Source)
at BestStudent.main(BestStudent.java:22)

我已经查看了有关此内容的其他主题,并且我已经仔细检查了所有变量是否已正确初始化。
