String[][][]threeDimensionalArray; 1. 在上面的代码中,我们声明了一个名为threeDimensionalArray的三维数组变量。请确保变量名称符合Java的命名约定。 为数组分配内存空间 接下来,我们需要为三维数组分配内存空间。我们知道三维数组由多个二维数组组成,因此我们需要为每个二维数组分配内存空间。 threeDimensionalArray=newS...
Example: 2-dimensional Array class MultidimensionalArray { public static void main(String[] args) { // create a 2d array int[][] a = { {1, 2, 3}, {4, 5, 6, 9}, {7}, }; // calculate the length of each row System.out.println("Length of row 1: " + a[0].length); Sys...
Two for loops are used to print all the six values from the two-dimensional array. The first index of thetwodim[i][j]array refers to one of the inner arrays. The second index refers to the element of the chosen inner array. $ java Main.java 1 2 3 1 2 3 In a similar fashion, ...

In the previous section, we created a two-dimensionalArrayList.Following the same logic, let’s create a three-dimensionalArrayList: Let’s assume that we want to represent a 3-D space.So, each point in this 3-D space will be represented by three coordinates, say, X, Y, and Z. ...
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...
