another way is to make a patch to Hash object, put ur own rules in it and u
will have a HashMap in ruby

The Ruby hash is not a Java HashMap

x["key"] = "value_1"
x["key"] = "value_2"

puts x["key"] => "value_2"

The best you can do is:
1) Create a HashMap class for Ruby, a very simple task
2) Use lists to store the values

x["key"] = Array.new
x["key"] << "value_1"
x["key"] << "value_2"

puts x["key"] => ["value_1", "value_2"]
