#    
#  Overview
In Ruby, one of the ways to get the length of an array is by using the **`size` method**. It returns an integer value representing the total number of elements in an array.

#    
#  Syntax
```ruby
array.size
```
#    
## Parameters
The `size` method takes no parameters.

##   
## Return value
The value returned is an integer value which is the number of elements an array contains.

##   
## Code example
In the code below, we will demonstrate the use of the `size` method. We created several arrays and got their lengths using the size method.

# create several arrays
arr1 = [1, 2, 3, 4, 5]
arr2 = ["a", "b", "c", "d", "e", "f", "g", "h"]
arr3 = ["FireFox", "Chrome", ]
arr4 = []
arr5 = ["Google", "Meta", "Netflix", "Apple", "Amazon"]
arr6 = ["Java", "Ruby"]

# find the length of arrays
# using the count method
a = arr1.size
b = arr2.size
c = arr3.size
d = arr4.size
e = arr5.size
f = arr6.size

# print the returned values
puts a
puts b
puts c
puts d
puts e
puts f

In the code above, `0` is returned for the length of `arr4` simply because it is an empty array.

How to find the length of an array using the size method

`array.size` in Ruby returns an integer representing the total number of elements in the array.
