Java 定义类，设置构造方法，输入，输出

定义一个学生类Student，要求：
（1）设置类中私有成员变量sno表示学号，sname表示姓名，sage表示年龄，sscore表示成绩。
（2）设置带参构造方法，对成员完成赋值操作。
（3）设置其他方法成员：getno()从键盘获得学号；getname()从键盘获得姓名；getsage()从键盘获得年龄；sscore()从键盘获得成绩
（4）根据Student的定义，创建五个学生类对象，输入并输出学生信息。

import java.util.Scanner;
public class Student {
  String sno;
  String sname;
  int sage;
  int sscore;
  public Student(){}
  public Student(String sno,String sname,int sage,int sscore){
    this.sno = sno;
    this.sname = sname;
    this.sscore = sscore;
    this.sage = sage;
  }

    Scanner input = new Scanner(System.in);
    System.out.println("请输入学号：");
    this.sno = input.next();
