In Java, the Collection framework provides a set of interfaces and classes to handle groups of objects. The framework offers various operations to manipulate and perform calculations on collections, such as finding the sum of elements in a collection. This article will discuss how to calculate the...
注意:和ArrayList想比,不变的是方法名称与执行结果,变化的是底层的数据结构(数组为双向链表)与操作方式改变(如remove()方法:节点指向发生改变) LinkList实现来List<>接口,还实现了Deque接口(说明LinkList,可以作为线性表,栈,队列来使用)。也说明方法比ArrayList的方法更多。 Linklist的方法 import java.util.LinkedLis...
