删除map集合 ，List集合中的指定元素

Map:

for (Iterator<String> iterator = map.keySet().iterator();iterator.hasNext();){
    String key = iterator.next();
    if (......){
          iterator.remove();
    }
}

List:

Iterator<Integer> iterator = list.iterator();
while ( iterator.hasNext() ){
       Integer str = iterator.next();
       if (.......){
       iterator.remove();
       }
}
