Arrays and their usage in Java programs

We might have come across the term array in the past, so let's see what arrays are with an explanation and an example.

An array is a container that stores multiple values of the same data type.

In the following example, we will see what a container is, how to define that container, and how we can store values in them.

If we want to work with arrays, we declare them by allocating some space for them using the following code:

int a[] = new int[];

The new keyword basically allocates memory for a value in this array. The square brackets mean that we are adding multiple values into the brackets, [] indicates the term for the array. To define an array, we have to create space for the multiple values that we will be storing in it. In this example, we have five integer values that we are planning to store in the array, which is why we have specified the array data type as an integer, and the number of variables to be added is given in the square brackets:

int a...
