Ruby Case Statement

In Ruby, we use ‘case’ instead of ‘switch’ and ‘when’ instead of ‘case’. The case statement matches one statement with multiple conditions just like a switch statement in other languages.

Syntax:

  case expression  [when expression [, expression …] [then]     code ]…  [else     code ]  end  

Example:

  #!/usr/bin/ruby   print “Enter your day: ”   day = gets.chomp   case day   when “Tuesday”     puts ‘Wear Red or Orange’   when “Wednesday”     puts ‘Wear Green’   when “Thursday”     puts ‘Wear Yellow’    when “Friday”     puts ‘Wear White’    when “Saturday”     puts ‘Wear Black’   else     puts “Wear Any color”   end   

Output:

Ruby switch 1

Look at the above output, conditions are case sensitive. Hence, the output for ‘Saturday’ and ‘saturday’ are different.
