How do I declare multidimensional arrays in Java?

In Java, you can declare a multidimensional array by specifying the number of dimensions. For example, to declare a 2D array, you can use: int[][] array = new int[3][4]; This creates a 2D array with 3 rows and 4 columns.

Can you show me how to initialize it with values?

Sure! You can initialize a 2D array with values like this: int[][] array = {{1, 2, 3, 4}, {5, 6, 7, 8}, {9, 10, 11, 12}}; This creates a 2D array with the specified values.

What if I want to declare a 3D array?

To declare a 3D array, you can do it like this: int[][][] array3D = new int[2][3][4]; This creates a 3D array with 2 layers, 3 rows, and 4 columns.

How do I access an element in a multidimensional array?

You can access an element by specifying its indices. For example, array[1][2] accesses the element in the second row and third column of a 2D array.
