Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value

The length of an array is established when the array is created.

An array is a collection of similar types of data.

In the Java array, each memory location is associated with a number. The number is known as an array index.

Elements must be of the same type in a Java Array.
