How to center a string in Ruby with the center() method

Overview

We can use the center() method to center a string in Ruby. The center() method centers a string in the specified width. If the specified width is greater than the string, center() returns a new string with a length equal to the width.

Syntax

str.center(width)

Parameters

  • str: the string you want to center.

  • width: the width in which you want to center the string.

Return value

center() returns a new string.

Code example

In the example below, we will create some strings and center them with the center() method.

# create some strings

str1 = "Hello" 

str2 = "Edpresso"

str3 = "is"

str4 = "the"

str5 = "best"



# center strings

a = str1.center(10)

b = str2.center(7)

c = str3.center(20)

d = str4.center(5)

e = str5.center(5)



# print returned values

puts a 

puts b

puts c

puts d

puts e

NOTE: When the width is less than the length of the original string, the center() method returns the original string.
