the error is in the SavingsAccount class and i have commented in the error on the correct line.
SavingsAccount
public class SavingsAccount extends Account

}
public void withdraw(int number, double amt)
{
SavingsAccount sa = accounts.get(find(number)); //error: "cannot find symbol - method find(int)"
sa.withdraw(amt);

}
one more thing: the toString() method that is the last line in the class right above, can i write that better? is there a way to break it up so it isn't so long? i had to change that method from a print() to a toString() so i am just learning this toString() method.
