How to check if an Array is Not Empty in Ruby - Step by Step Examples

How to check if an Array is Not Empty in Ruby ?

In Ruby, you can use the empty? method to check if an array is not empty.

In this example,

We create an array named numbers with some elements.
We check if the array is not empty using the empty? method and negate it, and store the result in the variable notEmpty.
Finally, we print whether the array is not empty or not.

numbers = [1, 2, 3]
notEmpty = !numbers.empty?
puts "Array is not empty: #{notEmpty}"

Array is not empty: true

In this example,

We create an empty array named emptyArray.
We check if the array is not empty using the empty? method and negate it, and store the result in the variable notEmpty.
Finally, we print whether the array is not empty or not.

emptyArray = []
notEmpty = !emptyArray.empty?
puts "Array is not empty: #{notEmpty}"

Array is not empty: false
