ruby on rails - How to access first item in hash value array -

i have hash value array of song lyrics (line1, line2, etc..)

code:

class song     def initialize(lyrics)        @lyrics = lyrics      end     def get_song_name()         puts @lyrics.keys     end     def get_first_line()         puts @lyrics.values[0]     end end  wasted = song.new({"wasted" => ["i better when we're wasted",     "it makes easier see"]})  real_world = song.new("real world" => ["straight want learn here", "if else fall apart"])  wasted.get_song_name() wasted.get_first_line() #=>i better when we're wasted #=>it makes easuer see 

so when called wasted.get_first_line, want first item in array of value. tried doing @lyrics.values[0], returns both lines of song instead of first one.

how accomplish this?

you need understand in above code @lyrics hash. here doing , translates to:

@lyrics # => {"wasted"=>["i better when we're wasted", "it makes easier see"]}    @lyrics.values # => [["i better when we're wasted", "it makes easier see"]]   @lyrics.values[0] # => ["i better when we're wasted", "it makes easier see"]   @lyrics.values[0][0]  # => "i better when we're wasted"  

therefore access first line, need first element of values array. i.e.

@lyrics.values[0][0] 

or

@lyrics.values.first.first
