How to check if Two Arrays are Equal in Ruby - Step by Step Examples

How to check if Two Arrays are Equal in Ruby ?

Answer

To check if two arrays are equal in Ruby, you can use the == operator for arrays with the same elements and manually compare elements for arrays with different elements.

✐ Examples

1 Arrays with Same Elements

In this example,

We create two arrays named arr1 and arr2 with the same elements.
We then use the == operator to check if the arrays are equal and store the result in the variable equal1.
The == operator checks if two arrays have the same elements in the same order.
Finally, we print the value of equal1 to the console.

Ruby Program

arr1 = [1, 2, 3]
arr2 = [1, 2, 3]
equal1 = arr1 == arr2
puts "Arrays are equal: #{equal1}"

Output

Arrays are equal: true

2 Arrays with Different Elements

In this example,

We create two arrays named arr3 and arr4 with different elements.
We then manually compare each element of both arrays and store the result in the variable equal2.
If all elements are equal, equal2 is set to true; otherwise, it's set to false.
Finally, we print the value of equal2 to the console.

Ruby Program

arr3 = [1, 2, 3]
arr4 = [3, 2, 1]
equal2 = true
arr3.each_with_index do |elem, index|
  unless elem == arr4[index]
    equal2 = false
    break
  end
end
puts "Arrays are equal: #{equal2}"

Output

Arrays are equal: false
