A bank account is made up of transactions. In this video, we're going to create methods to add transactions to our bank account. The transactions can be credits or debits and affect the running balance.
Code Samples
class BankAccount
attr_reader :name
def initialize(name)
@name = name
@transactions = []
add_transaction("Beginning Balance", 0)
end
def credit(description, amount)
add_transaction(description, amount)
end
def debit(description, amount)
add_transaction(description, -amount)
end
def add_transaction(description, amount)
@transactions.push(description: description, amount: amount)
end
end
bank_account = BankAccount.new("Jason")
bank_account.credit("Paycheck", 100)
bank_account.debit("Groceries", 40)
puts bank_account.inspect
Returns the following:
#<BankAccount:0x007f00882acbc0
@name="Jason",
@transactions=[
{:description=>"Beginning Balance", :amount=>0},
{:description=>"Paycheck", :amount=>100},
{:description=>"Groceries", :amount=>-40}
]>
