Ruby – How do I learn in class?

class X
 def initialize
 @name = "Bob"
 end
 blah blah
end

puts X.new # I want this to print X:Bob
puts [X.new, X.new] # I want this to print [X:Bob, X:Bob] 

class X
 def initialize
 @name = "Bob"
 end

 def to_s
 "X:#{@name}"
 end
end

puts X.new # prints X:Bob
puts [X.new, X.new].to_s # prints [X:Bob, X:Bob ]

class X
 def initialize
 @name = "Bob"
 end
 blah blah
end

puts X.new # I want this to print X:Bob
puts [X.new, X.new] # I want this to print [X:Bob, X :Bob]

Override the to_s method of the class:

class X
 def initialize
 @name = "Bob"
 end

 def to_s
 "X:#{@name}"
 end
end 

puts X.new # prin ts X:Bob
puts [X.new, X.new].to_s # prints [X:Bob, X:Bob]
