- Arrays and linked lists are two fundamental data structures, representing two different ways data can be stored in computer memory: contiguous memory storage and scattered memory storage. The characteristics of the two complement each other.
|
||||
- Arrays support random access and use less memory; however, inserting and deleting elements is inefficient, and the length is immutable after initialization.

|
||||
In contrast, array elements must be of the same type, so that the corresponding element position can be obtained by calculating the offset. For example, if an array contains both `int` and `long` types, with individual elements occupying 4 bytes and 8 bytes respectively, then the following formula cannot be used to calculate the offset, because the array contains two different "element lengths".
|
||||
|
||||
```shell
|
||||
# Element memory address = Array memory address (first element memory address) + Element length * Element index
|
||||
# Element Memory Address = Array Memory Address (first Element Memory address) + Element Length * Element Index
