题目:reverse words in a string Given an input string, reverse the string word by word. For example, Given s = "the sky is blue", return "blue is sky the". 解析:将字符串中的单词逆序输出 借助一个堆栈,从前向后遍历字符串,遇到空,跳过,直到非空字符,拼接word,等再次遇到空时,得到一个word,...
java中reverse的使用案例 java中reverse的使⽤案例reverse()⽅法表⽰的是将⼀个输⼊流倒叙输出。举例：StringBuffer sb =new StringBuffer("abcd");System.out.println(sb.reverse().toString());输出结果：dcba；备注：此⽅法针对的是io流，不能针对字符串。
Java中的thenComparing reverse方法实现 本文将教会刚入行的小白如何使用Java中的thenComparing reverse方法。首先,我们来看一下整个实现的流程。 开始创建Comparator对象使用thenComparing方法使用reversed方法返回反转排序的Comparator对象 创建Comparator对象 首先,我们需要创建一个Comparator对象,用于比较两个对象的属性。通过比较属...
int indexOf(obj):获取指定元素的位置。 ListIterator listIterator(); === 面试考点: ——ArrayList 线程不安全,查询速度快 ——Vector 线程安全,但速度慢,已被ArrayList替代 ——LinkedList 链表结果,增删速度快 4、Set接口 Set:元素是无序(存入和取出的顺序...
