Two-Dimensional Arrays

Two dimensional arrays allow the programmer to store and access data in rows and columns of a grid.

// Initializes a 3 by 2 array of integers and prints its contents

public class Test2dArray{
    public static void main(String[]args){
        // Create the array and set its contents to 1-6
        int [][] array = new int[3][2];
        int data = 1;
        for (int row = 0; row < array.length; row++)
            for (int column = 0; column < array[row].length; column++){
                array[row][column] = data;
                data++;
            }
        // Print the contents of the array in grid format
        for (int row = 0; row < array.length; row++){
            for (int column = 0; column < array[row].length; column++)
                System.out.print(array[row][column] + " ");
            System.out.println();
        }
    }
}
