Handling multidimensional arrays

A multidimensional array is an array of arrays. In Java, you can create arrays with two or more dimensions. The most common type of multidimensional array is the two-dimensional array, also known as a matrix or a table, where the elements are arranged in rows and columns.

Let’s see how to create multidimensional arrays.

Declaring and initializing multidimensional arrays

To declare a two-dimensional array, you need to specify the data type of the elements, followed by two sets of square brackets ([][]) and the name of the array. Take the following example:

int[][] matrix;

Just like the one-dimensional array, we initialize a two-dimensional array with the use of the new keyword, followed by the data type and the size of each dimension inside the square brackets, like this:

matrix = new int[3][4];

This code initializes a matrix of 3 rows and 4 columns. The type is int, so we know that the values of the matrix are integers.
