Question

class cf
{    int sNo;
     String sName;
     String sSex;
     int sAge;
     double sJava;
        void set(int sNo,String sName,String sSex,int sAge,double sJava)
            {     this.sNo = sNo;
                  this.sName= sName;
                  this.sSex = sSex;
                  this.sAge = sAge;
                  this.sJava = sJava;
            }
                  int getAge() 
                      {
                             return sAge;
                      }
                  double getJava() 
                      {
                             return sJava;
                      }                  String getName()
                      {
                             return sName;
                      }                 int getSNo() 
                      {
                             return sNo;
                      }
                 String getSex() 
                      {
                             return sSex;
                      }
};
import java.util.Scanner;
public class Studet
{    public static void main(String[] args)
     {    cf input=new cf();
           int sNo;
           String sName;
           String sSex;
           int sAge;
           double sJava;
           input.set(sNo,sName,sSex,sAge,sJava);
           Scanner scanner=new Scanner(System.in)
               int sNo=scanner.nextInt();
               string sName=scanner.next();
               string sSex=scanner.next();
               int sAge=scanner.nextInt();
               double sJava=scanner.nextDouble();
           System.out.println(x.getAge());
           System.out.println(x.getJava());
           System.out.println(x.getName());
           System.out.println(x.getSNo());
           System.out.println(x.getgetSex());
     }
}
    怎么运行之后说是       import  java.io.*;   这里有问题
究竟是怎么一回事呀 
         大虾帮我看看 ！！！！

Answer 1

是       import    java.util.Scanner;
这里出现问题啊
