Ruby Array

Question

EDIT : First part removed i found the answer.

I have the following problem : im reading a number from the input and trying to use that number to access a given array position. I get the following results

value #=> "0"
value.to_i #=> 0
myArray[0] #=> MyObject
myArray[value.to_i] #=> nil

Answer 1

That works for me.

irb(main):012:0> myArray = ['first']
=> ["first"]
irb(main):013:0> value = '0'
=> "0"
irb(main):014:0> myArray[value.to_i]
=> "first"

Answer 2

Try myArray[Integer(value)] (although value.to_i works for me as well):

>> value = "0"
=> "0"
>> myArray = ["a", "b"]
=> ["a", "b"]
>> myArray[0]
=> "a"
>> myArray[Integer(value)]
=> "a"

Answer 3

Thank you for all your replies, i was trying to access and array inside a class variable with:

@myclass.myarray[value]

when i made a getter method and accessed myarray inside the object the error disappeared. If anyone can explain this behavior please let me know
