Apart from **linear arrays**, there is another type of array known as **two dimensional array**. Let’s discuss briefly about it.


# What are two-dimensional arrays?
Unlike linear arrays, two-dimensional arrays are just like an *m* x *n* matrix with __m__ number of *rows* and __n__ number of *columns*.
## Declaration
The declaration of *2-d arrays* is as follows:
```JAVA
 Datatype[m][n] name;
```
The elements in a two-dimensional array are arranged in the form of rows and columns.

## Instantiation

The instantiation of a character array with 2 rows and 2 columns will be as:
 

In this lesson, an introduction of another type of Arrays known as two-dimensional Array is provided.
