从键盘输入五个学生的姓名和成绩，按成绩的高低输出学生的姓名和成绩

Question

import java.util.*;
class Student implements Comparable{
int score=0;
String name;
Student(int score,String name){
this.score=score;
this.name=name;
}
public int compareTo(Object b){
Student st=(Student)b;
return(this.score-st.score);
}
}
public class TextTreeSet {
public static void main(String args[]){
TreeSet<Student> tree=new TreeSet<Student>();
System.out.println("请输入5个学生的姓名和分数");
Scanner reader=new Scanner(System.in);
Student st1,st2,st3,st4,st5;
st1=reader.next();
st2=reader.next();
st3=reader.next();
st4=reader.next();
st5=reader.next();
tree.add(st1);
tree.add(st2);
tree.add(st3);
tree.add(st4);
tree.add(st5);
Iterator<Student> te=tree.iterator();
while(te.hasNext()){
Student stu=te.next();
System.out.println(stu.name+" "+stu.score);
}
}
}
程序中的
st1=reader.next();
st2=reader.next();
st3=reader.next();
st4=reader.next();
st5=reader.next(); 是错的，怎么才能改好？

Answer 1

Student st1 = new Student(reader.nextFloat(),reader.next());
Student st2 = new Student(reader.nextFloat(),reader.next());
Student st3 = new Student(reader.nextFloat(),reader.next());
Student st4 = new Student(reader.nextFloat(),reader.next());
Student st5 = new Student(reader.nextFloat(),reader.next());
//说明一下输入的格式：分数+空格+姓名+回车或者空格
//示例：
//100 Tom
