定義一個ArrayList集合物件，向其中添加兩個學生資訊，并列印輸出該集合物件中每個元素的值
import java.util.ArrayList;
import java.util.Iterator;
public class Test{
public static void main(String[] args){
Student s1=new Student("2016001","張三","男",21);
Student s2=new Student("2016002","李四","男",22);
List<Student> list=new ArrayList<Student>();
list.add(s1);
list.add(s2);
Iterator<Student> it=_______________ //獲取迭代器
//判斷是否還有元素
while( ____________ ){
Student s=it.next();
String sno=s.getSno();
String name=s.getName();
String sex=s.getSex();
int age=s.getAge();
System.out.println(sno+" "+name+" "+sex+" "+age);
}
}
橫線上填什么？

list.iterator();it.hasNext()
這問題問百度就行了，貼子太費時間
