Iterator转List

方式1：
#Apache Commons Collections:
import org.apache.commons.collections.IteratorUtils;
Iterator myIterator = //some iterator
List myList=IteratorUtils.toList(myIterator);   
 
 
方式二：
或者自己转换
public static  List copyIterator(Iterator iter) {
    List copy = new ArrayList();
    while (iter.hasNext())
        copy.add(iter.next());
    return copy;
}
 
使用方式：
List list = Arrays.asList("1", "2", "3");
Iterator iter = list.iterator();
List copy = copyIterator(iter);
 
方式3：
#Guava
import com.google.common.collect.Lists;
Iterator myIterator =  //some iterator
List myList = Lists.newArrayList(myIterator);
