今天做了个关于类的使用,但是输入名字的时候报错,编译是通过了,求帮助啊

package as.bs;
import *;
import java.util.Scanner;

  class Student{
    int ID,grade;
    String name;
    double Ms,Es;
    void setStudent(String k,int i,int g){
        name=k;
        ID=i;
        grade=g;
    }
    void setScores(double m,double n){
            Ms=m;
        Es=n;
    }
   
    String getAll(){
        return name;
    }
    void getInformation(){
        System.out.println("名字为"+getAll());
        System.out.println("ID"+ID);
        System.out.println("Ms"+Ms);
        System.out.println("Es"+Es);
        System.out.println("grade"+grade);
    }
    double sum(){
    return Ms+Es;
    }
}
/*import *;*/
//import java.util.Scanner;
    public class Comeon{
       public static void main(String[] args){
        Scanner sc=new Scanner(System.in);
        String name;
                System.out.println("请输入你的名字");
                name=sc.next();
        //char k=(char)System.in.read();
        //Scanner sc=new Scanner(System.in);
        System.out.println("请输入你的ID");
        int ID=sc.nextInt();
        System.out.println("请输入你的年纪");
        int g=sc.nextInt();
        System.out.println("请输入你的math");
        double m=sc.nextDouble();
        System.out.println("请输入你english");
        double n=sc.nextDouble();
    Student s1=new Student();
    Student s2=new Student();
    s1.setStudent(name,ID,g);
    s1.setScores(m,n);
   
    System.out.println(s1.sum());
    s1.getInformation();
    }
}
