Java 二维数组（2D Array）是一维数组在多维方向上的自然扩展，也是矩阵运算、图像处理、棋盘类算法等场景中最基础的数据载体。本文以 cosmos 仓库中 readme-2DArray.md 为主线，结合同一目录下的可运行示例 2d-array.java 与 2d-array-list-java.java ，系统讲解二维数组的定义、声明、初始化、动态创建、遍历 ...
一、从动态数组到二维 ArrayList：核心概念 ArrayList 是数组（Array）的动态版本。原生数组在声明时必须预定义长度，而 ArrayList 内部维护一个可扩容的底层数组，当元素数量超过当前容量时会自动增长，因此使用者在多数场景下无需关心容量上限。
