import java.util.*;
class IteratorText
{
public static void main(String args[])
{
ArrayList al=new ArrayList();

al.add("wangxin");//public void add(E o);
al.add("jianghui");
Iterator it=al.iterator();
while(it.hasNext());
{
it.next();
it.remove();

}
}
System.out.println(al.isEmpty());
}
出现以下错误:
iterator.java:19: cannot resolve symbol
symbol : class out
location: class java.lang.System
System.out.println(al.isEmpty());
^
2 errors

[zephyr_cc]

while(it.hasNext());
后面分号去了
System.out.println(al.isEmpty());
扔到main方法里面
