element() 和 peek() 用于在队列的头部查询元素。与 remove() 方法类似,在队列为空时, element() 抛出一个异常,而 peek() 返回 null。 下面是Java中Queue的一些常用方法: add 增加一个元索 如果队列已满,则抛出一个IIIegaISlabEepeplian异常 remove 移除并返回队列头部的元素 如果队列为空,则抛出一个NoSuch...
队列是一种特殊的线性表,它只允许在表的前端进行删除操作,而在表的后端进行插入操作。 LinkedList类实现了Queue接口,因此我们可以把LinkedList当成Queue来用。 Java中Queue有一些常用的方法: offer、add poll、remove peek、element 每一行中的两个函数,实现的功能是一样的,但也有所不同。 offer,add区别: 一些队列...
可以分别实现队列栈和双端队列 继承Queue的方法:尾部添加(add, offer),查看头部元素(element,peek),删除头部元素(remove,poll) 继承Deque的方法: 对应队列 Java使用Queue学习小结 队列Queue实现了一个先进先出(FIFO)的数据结构: -通过add()/offer()方法将元素添加到队尾; -通过remove()/poll()从队首获取元素...
