} } 1. The following two classes are used to help solve part A and B of this problem. } } /**The class SingleTable represents a table at a restaurant.*/ public class SingleTable { /** SingleTable has a zero parameter constructor */ public SingleTable () { /implementation not shown */ /** Returns the number of seats at this table. The value is always greater or equal to 4. */ public int getNumSeats () { /* implementation not shown */ /** Returns the height of this table in centimeters. */ public int getHeight() { /* implementation not shown */ /** Returns the quality of the view from this table */ public double getViewQuality() { } /** implementation not shown */ /** Sets the quality of the view from this table */ public void setViewQuality (double quality) { /** implementation not shown */ //there may be other constructors, fields, methods not shown /**Restaurant represents all the tables at a restaurant*/ public class Restaurant ( public ArrayList tableList; //there may be other constructors, fields, methods not shown /** Calculates and returns the average view quality of all of the tables in the tableList field */ public double getAverageView() { } /** implementation not shown */ Part A) Write a complete class CombinedTable that extends SingleTable This class represents a table that has been made by combining two single tables together. 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.
