# Array Review
|
|
|
|
## What is an Array:
|
|
- An (reference) object used to store a **list** of values
|
|
- A **contiguous** block of memory is used to store the values.
|
|
- Each **cell** holds a value
|
|
- All the values are the same **type**
|
|
- It can store all kinds of data, `int`, `double`, `object`, etc, the type stored can be primitive (`int`) or reference (`object`)
