Learn the basic concepts of Java such as loops, methods, and arrays.

Android Development with Java

This module will be our guide on getting started with Java. We'll start with a simple “Hello World” program and proceed to cover common concepts such as conditional statements, loops, math, and logic in Java. Then, we’ll move to more advanced concepts like inheritance, generics, and array lists, along with much more.
By the time we're done, we'll have enough knowledge to write simple Java programs.

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.
