Method Summary

static double	getIntRate() we need a way of determining the interest rate Static - since interest rate is static - once per class
double	getIntYTD() report the year to date interest
static void	main(java.lang.String[] args)
double	payInterest(int numDays) pay interest into the calling Account based on the number of days paying interest for (also, the class knows the interest rate) Return: amount of interest paid
boolean	payInterestfirstVersion(int numDays) MAR - I think the above is better pay interest into the calling Account based on the number of days paying interest for (also, the account knows the interest rate) Return: whether interest is paid
double	processMonthEnd() process month end - pay interest into the calling Account default version - pays based on 30 day months Return: new balance
double	processMonthEnd(int days) process month end - pay interest into the calling Account default version - pays based on days in month - passed Return: new balance
void	resetIntYTD() reset the year to date interest back to zero
static void	setIntRate(double rate) we need a way of setting the interest rate Static - since interest rate is static - once per class
void	setIntYTD(double amt) change the year to date interest
