< p > 许多编程语言都提供内置的列表，例如 Java、C++、Python 等。它们的实现比较复杂，各个参数的设定也非常有考究，例如初始容量、扩容倍数等。感兴趣的读者可以查阅源码进行学习。< / p >
< p > 为了加深对列表工作原理的理解，我们尝试实现一个简易版列表，包括以下三个重点设计。< / p >
2023-02-08 14:54:41 +08:00
< ul >
2023-04-07 22:32:13 +08:00
< li > < strong > 初始容量< / strong > ：选取一个合理的数组初始容量。在本示例中，我们选择 10 作为初始容量。< / li >
2023-09-17 01:11:45 +08:00
< li > < strong > 数量记录< / strong > ：声明一个变量 < code > size< / code > ，用于记录列表当前元素数量，并随着元素插入和删除实时更新。根据此变量，我们可以定位列表尾部，以及判断是否需要扩容。< / li >
2023-08-17 05:12:16 +08:00
< li > < strong > 扩容机制< / strong > ：若插入元素时列表容量已满，则需要进行扩容。首先根据扩容倍数创建一个更大的数组，再将当前数组的所有元素依次移动至新数组。在本示例中，我们规定每次将数组扩容至之前的 2 倍。< / li >
