In order to get full credit, your class must contain the following: . . A constructor that takes two Single Tables as Parameters o You should store these paramters as private class fields An override of getNumSeats - A combined table can seat a number of customers that is two fewer than the total number of seats in its two SingleTableObjects (to account for seats lost when the tables are pushed together). . An override of getViewQuality o If the two tables are the same height, the view quality is the average of the view quality of the two single table. o If the two tables are not the same height, the view quality is 10 units less than the average view quality of the two single tables. Part B) Write the getAverageView method from the Retaurant class.
