ruby check type
ruby object type
The proper way to determine the type of an object, is to call object.class.
Object.class method
object_name.class
first = "Hello World" second = 21 puts "The class of first is #{first.class}" puts "The class of second is #{second.class}"
ruby type
The class of first is String The class of second is Integer
ruby type of
This method is defined in the Object class of Ruby’s library and sorely used for checking the class of a particular object or instance.
Object_name.is_a?(Class_name)
ruby type of object
first = "Hello World" second = 21 if (first.is_a?(String) == true) puts "First is of String class" end if (second.is_a?(Integer) == true) puts "Second is of Integer class" end
First is of String class Second is of Integer class
