Multidimensional Arrays

 

We can even create multidimensional arrays i.e. arrays within arrays. We access values by providing an index for the array and another one for the value inside it. 

Example:

public class ArrayExample {
    public static void main(String[] args) {
        //creating array objects
        String[][] objects = {{"Spoon", "Fork", "Bowl"}, {"Salt", "Pepper"}};

        //accessing array elements using indexing
        System.out.println(objects[0][2]);
        System.out.println(objects[1][1]);
    }
}

Output:

Bowl
Pepper

 

We can also print the multi-dimensional array.

Example:

public class ArrayExample {
    public static void main(String[] args) {
        //creating array objects
        int[][] objects = {{1,2,3}, {4,5,6}};

        for (int i = 0; i < objects.length; i++) {
            for (int j = 0; j < objects[i].length; j++) {
                  System.out.print(objects[i][j] + "\t");
            }
            System.out.println();
        }    
    }
}

Output:

1    2    3    
4    5    6    

 

Use loops with arrays:

The simplest way of looping through an array is to use a simple for-each loop.

Example:

public class ArrayExample {
    public static void main(String[] args) {
        //creating array objects
        String[] objects = {"Spoon", "Fork", "Bowl", "Salt", "Pepper"};

        for (String i : objects) {
              System.out.println(i);
        }
    }
}

Output:

Spoon
Fork
Bowl
Salt
Pepper

 

Alternatively, you can also use a simple for loop to do the same.

Example:

public class ArrayExample {
    public static void main(String[] args) {
        //creating array objects
        String[] objects = {"Spoon", "Fork", "Bowl", "Salt", "Pepper"};

        for (int i = 0; i < objects.length; i++) {
              System.out.println(objects[i]);
        }    
    }
}

Output:

Spoon
Fork
Bowl
Salt
Pepper
