遍历List集合同时删除元素的正确方法

for(String x:list){ 
　　if(x.equals("del")) 
　　list.remove(x); 
}

会报错：

Exception in thread "main" java.util.ConcurrentModificationException
    at java.util.AbstractList$Itr.checkForComodification(Unknown Source)
    at java.util.AbstractList$Itr.next(Unknown Source)


解决办法：

public class TestIterator {

	public static void main(String[] args) {
		List<String> list=new ArrayList<String>();
		list.add("a");
		list.add("b");
		list.add("c");
		Iterator<String> stringIterator=list.iterator();
		while(stringIterator.hasNext()){
			String s=stringIterator.next();
			if(s.equals("c")){
				stringIterator.remove();
			}
		}
	}
}
