# Multi Dimensional Array In Java – Tutorial & Program

All the methods will be explained with sample programs and suitable examples. The compiler has also been added so that you understand the whole thing clearly.

• Using Standard Method
• Using For Loop
• Using Scanner Class
• Using String

An array, as we all know, is a collection of multiple elements of the same data type. Arrays are normally used to store information of one particular type of variable.

As the name of the title suggests, multi-dimensional means any particular entity having 3 or more than 3 dimensions in reality.

Similarly, a multi-dimensional array in Java usually has 3 or more defined indexes, but in reality, one particular row of elements have another multitude of elements defined on their names.

Basically, you can have a 3×3 or a bigger matrix of elements to define a multi-dimensional array. As you can see as per the image uploaded above, firstly, you need to specify the number of rows and columns respectively.

The example roughly explains the structure of a 3×4 matrix.

So, the total number of elements that will be entered is 12.

The elements that are entered are as follows:

1 2 3 4 5 6 7 8 9 10 11 12

These elements will be arranged accordingly and the multi-dimensional array will be printed for you.

Thus, the numerous methods that are used to carry out the same task in Java are:

## Multi Dimensional Array – Using Standard Method

Output:

### Multidimensional – Using For Loop

1. To insert the elements in to multi dimensional array a[][][], we are using for loop.

for i=0 to 2

for j=0 to 1

for k=0 to 1

insert the element at a[i][j][k].

2) Print the elements using for loops

for i=0 to 2

for j=0 to 1

for k=0 to 1

print a[i][j][k]

Output:

#### Using Scanner Class

1.  To insert  the elements in to multi dimensional array array[][][]  we are using scanner class.
2. for i=0 to 2
3. for j=0 to 1
4. for k=0 to 1
5. sc.nextInt() method reads the entered number and inserted the number in to array[i][j][k] .

Output:

##### Using String
1. Initialize the strings as elements in to the multi dimensional string array str[][][].

2) Print the strings from multidimensional array str[][][].

for i=0 to 2

for j=0 to 1

for k=0 to 1

print the string available at the index str[i][j][k].

Output:

x
