我用java写一个用迭代器来遍历链表老是出现错误，我想请问是怎么回事？
这是我的代码？
import java.util.*;
class student {
String name;
int number;
float score;
student(String name,int number,float score)
{
this.name=name;
this.number=number;
this.score=score;
}
}
public class A {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
LinkedList<student>list=new LinkedList<student>();
student stu1=new student("赵好明",9012,80.0f);
student stu2=new student("钱小青",9013,90.0f);
student stu3=new student("孙力枚",9014,78.0f);
student stu4=new student("周左右",9015,55.0f);
list.add(stu1);
list.add(stu2);
list.add(stu3);
list.add(stu4);
Iterator<student> it = list.iterator();
while (it.hasNext())
student t = it.next();
System.out.println(t.name+" "+t.number+" "t.score);
}
}
用eclipse运行时这里老出错：
student t = it.next();
System.out.println(t.name+" "+t.number+" "t.score);
