int[,] arr2D; // declare the array reference float[,,,] arr4D; // declare the array reference 声明之后,可以按如下方式为数组分配内存:C# 复制 arr2D = new int[5,4]; // allocate space for 5 x 4 integers 然后,可以使用以下语法访问数组的元素:C#...
int[] oneRow = array[row]; int oneCell = oneRow[column]; By placingint[] oneRow = array[row];above the inner loop, you can substitute all occurrences ofarray[row]withoneRowwithin the loop. In addition, whenever you declare it within the inner loop,counterwill remain0since its value ...
To declare a final variable, use the final keyword in Java before the variable declaration and initialize it with a value.
