Yet another Ruby Hello World Program

Trying hello world program once again

 

class Helloworld

    def initialize( name )

        @name = name

    end

 

    def setName(a_name)

        @name = a_name

    end

 

    def getName()

        return @name

    end

end

 

h = Helloworld.new( "Krish" )

puts h.getName()

h.setName( "Aiyana" )

puts h.getName()

 

 

Save the file with any name and extension as *.rb unlike java where top level class name has to be same as file name. Then execute the following command:

 

ruby name.rb

 

NOTE:

 

Do not forget to name the class with first letter as capital letter.

I didnt put the first letter of class name as capital letter and got the following error:

 

hw.rb:1: class/module name must be CONSTANT
