How do I pass multi-dimensional arrays to methods in Java?

In Java, you can pass multi-dimensional arrays to methods by specifying the array type in the method parameters. For example, to pass a 2D array, you can define your method like this: void myMethod(int[][] array) { ... }.

Can you show me an example of how to use that in a method?

Sure! Here's a simple example:

public class Example {
    public static void main(String[] args) {
        int[][] myArray = {{1, 2, 3}, {4, 5, 6}};
        printArray(myArray);
    }

    static void printArray(int[][] array) {
        for (int i = 0; i < array.length; i++) {
            for (int j = 0; j < array[i].length; j++) {
                System.out.print(array[i][j] + " ");
            }
            System.out.println();
        }
    }
}

This will print the elements of the 2D array.

What if I want to pass a 3D array instead?

You can pass a 3D array in a similar way. Just define your method with the appropriate type:

void myMethod(int[][][] array) { ... }

And you can create and pass a 3D array like this:

int[][][] my3DArray = {{{1, 2}, {3, 4}}, {{5, 6}, {7, 8}}};
myMethod(my3DArray);
