Java Notes
Programming: Kingdom - Buy Land
Name ______________________________
To the Kingdom class (see Kingdom), add
a method called buyLand
, which takes one parameter which is the
amount of land to buy. This method will decrease the amount of stored grain
by the amount needed to buy the land, and increase the amount of land.
A constant, SEED_REQUIRED_PER_ACRE
,
defines how much grain it takes to buy one acre of land.
Design decisions. You must decide exactly how to declare
this method (public
?, private
?, static
?,
void
?, double
?, etc).
Restriction. Don't allow more grain to be used than there is.
