How to Initialize an Array in Ruby - Step by Step Examples
How to Initialize an Array in Ruby ?
Answer
To initialize an array in Ruby, you can use array literals or the Array.new constructor.
✐ Examples
1 Initialize Array using Array Literals
In this example,
- We declare an array named
numbers
with integer values using array literals. - This creates an integer array in Ruby.
- We print the array elements.
Ruby Program
numbers = [1, 2, 3, 4, 5]
puts numbers.join(' ')
Output
1 2 3 4 5
2 Initialize Array using Array.new Constructor
In this example,
- We declare an array named
fruits
with character values using theArray.new
constructor. - This creates a character array in Ruby.
- We print the array elements.
Ruby Program
fruits = Array.new(3, 'Apple')
puts fruits.join(' ')
