I don't know why my answer is not working
class BankAccount
attr_reader :name
def initialize(name)
@name = name
@transactions = []
add_transaction("Beginning Balance", 0)
end
def balance
balance = 0
@transactions.each do |transaction|
balance += transaction[:amount]
end
balance
end
def debit(description, amount)
add_transaction(description, -amount)
end
def credit(description, amount)
add_transaction(description, amount)
end
def add_transaction(description, amount)
@transactions.push(description: description, amount: amount)
end
def to_s
puts "Name: " + @name + ", Balance: " + balance
end
end

Treehouse TeacherThere are two issues with this code.
The balance
method returns an Integer value. Numeric values can't be concatenated with strings:
puts "hi" + 2 # in `+': no implicit conversion of Fixnum into String (TypeError)
But if you use string interpolation, a numeric value can be substituted into a string:
puts "hi #{2}"
Try updating your to_s
method to use string interpolation.
The second issue is that to_s
needs to return a string value, not print it. Don't call puts
, just have to_s
return the string you create. See this video for more info.
