Concept: Each element in an array is a one-dimensional array, and the array is called a two-dimensional array.静态初始化：Static initialization:动态初始化：Dynamic initialization:注：其中列个数可以省略不写，因为Java中的二维数组存在不规则矩阵这样的数组，因此写了也没有多大意义。Note: The number of...

2. Two-Dimensional Array The key in working with elements of an array is knowing how to get a specific element from that array. For a two-dimensional array, we use row and column indices to get elements of an array. For this problem, we’ll use the following diagram to show how to ...
