$1.$ Write a Point class. The Point class should be written as an abstract data type.

$2.$ Include the following instance variables:

a$.$ an integer representing the x coordinate

b$.$ an integer representing the y coordinate

c$.$ The instance variables in your program should only be directly accessible inside of the Point

class.

$3.$ Have $2$ constructors for the Point class.

a$.$ a no$-$arguments constructor, set both of the instance variables to $0($zero$).$

b$.$ a constructor having two arguments, one for each of the two instance variables, set the instance

variables to those argument values.

$4.$ Include get and set methods for each of the two instance variables identified in step $2.$

$5.$ Include a toString method in your Point class. The toString method should be accessible to any program

and should return the values of the two instance variables. Values must be labeled; e$.$g$.$The xcoordinate $=15.$ DO NOT print from within the toString method.

$6.$ Write a client program $($also known as a driver, tester$).$ See the Time$1$Test program in Figure $8\mathrm{.}2$ of

your Deitel book. Use this program as a model to write your program. Your program will have the

same intent but will follow the procedure as outlined below. Name your program PointTest.

$7.$ In the PointTest class,

a$.$ Print your name, Lab number, and date as the first three lines of output. Hard$-$code the date...do

not use the system date.

b$.$ Create an object of type Point using the no$-$arguments constructor. Call this point$1$

c$.$ Create a second object of type Point using the two$-$argument constructor. Call this point$2.$ Use

the values of x $=11,$ y $=24$

d$.$ Display point $1$ instance variables after a call to point$1.$toString$()$

e$.$ Display point $2$ instance variables after a call to point$2.$toString$()$

f$.$ Change the x value of point$1$ to $35$ using the set method for the x value of point$1$

g$.$ Display point $1$ instance variables after a call to point$1.$toString$()$

h$.$ Display point $2$ instance variables after a call to point$2.$toString$()$

i$.$ Change the y value of point$2$ to $13$ using the set method for the y value of point$2$

j$.$ Display point $1$ instance variables after a call to point$1.$toString$()$

k$.$ Display point $2$ instance variables after a call to point$2.$toString$()$

$8.$ Here is an example of the output. Your version may vary, though your values should match mine.
