You will be creating a class called Seating. This class should be defined in a file named “Seating.java”. The

class Seating will contain 2 dimensional array called “seating” of Employee objects as its instance variable. The class Seating must include the following constructor and methods. (If your class does not contain any of the following methods, points will be deducted.)

Method	Description of the Method
public Seating(int rowNum, int columnNum)	It instantiates a two dimensional array of the size “rowNum” by “columnNum” specified by the parameters. Then it initializes each employee element of this array using the constructor of the class Employee without any parameter. So each employee will have default values for its instance variables.
private Employee getEmployeeAt(int row, int col)	It returns an employee at the indexes row and col (specified by the parameters of this method) of the array “seating”.
public boolean assignAt(int row, int col, Employee tempEmployee)	The method attempts to assign the “tempEmployee” to the seat at “row” and “col” (specified by the parameters of this method). If the seat has a default employee, i.e., an employee with the name “???”, then we can assign the new employee “tempEmployee” to that seat and the method returns true. Otherwise, this seat is considered to be taken by someone else; the method does not assign the employee and returns false.
public boolean checkBoundaries(int row, int col)	The method checks if the parameters row and col are valid. If at least one of the parameters “row” or “col” is less than 0 or larger than the last index of the array (note that the size of rows and columns can be different), then it return false. Otherwise it returns true.
public String toString( )	Returns a String containing information of the “seating”. It should show the list of employees assigned to the seating using the toString method of the class Employee (it shows first name initial of each employee) and the following format: The current seating G. H. ?. C. ?. B. ?. ?. ?. Please see the sample output listed below.

After compiling Employee.java, Seating.java, and Assignment8.java files, you need to execute Assignment8 class.
