在使用ArrayList移除特定字符时,直接调用list.remove('的')只能移除第一个匹配的字符,并且只能移除一个。如果需要移除列表中所有的'的',可以使用Iterator进行遍历,并通过调用Iterator的remove方法来移除匹配的元素。代码示例如下:for(Iterator iterator = list.iterator();iterator.hasNext();) { char c...

PriorityQueue允许重复,最小的值具有最高的优先级(如果是String,空格也可以算作值,并且比字母的优先级高)。Integer,String和Character可以与PriorityQueue一起使用,因为这些类已经内置了自然排序。如果想在PriorityQueue中使用自己的类,则必须包含额外的方法以产生自然排序,或者必须提供自己的Comparator。
