Description
To accomplish this project you will need the
Point class. I supplied you with
Point.class, which is the Byte Code version of Point.java.
Steps to get the Point class working with your
Project:
READ THE
DIRECTIONS CAREFULLY
1) Download Point.class
2) You need to create a new folder named proj3File, anywhere you want and place Point.class in that folder.
3) Go
to NETBEANs
4) RIGHT CLICK on your project.
5) Go
to properties
6) A
new window should appear. On the left,
click on Libraries.
7) Then
on the right, click on Add JAR/Folder
8) Find
the proj3File folder you created earlier and press open.
9) Then
press ok.
Everything
should be ready to go.
10)
Create a file named LastNameProj3.java,
where LastName is YOUR Last Name.
11) You
should declare and instantiate a Point object by using 1 of the 2 Constructors below.
You
can type
Point
x = new Point(); //This calls the Default Point Constructor
Or
Point
x = new Point(3,2); //This calls the parameterized
Point constructor which allows you to make any point you want.
12)
System.out.println() your point to make sure that it is working. If you see the point then it is working.
13) You
can delete the 2 lines you just wrote and start the project.

Point Class API
This class represents a Point on the xy
coordiate plane (x, y). I chose to make
x and y doubles in case you want to use the Midpoint formula in your proofs.
|
Constructor
Summary |
|
|
Point() default Point Constructor the
constructor initializes the newly created Point by setting it to the point
(5.0, 5.0) |
|
|
Point(double x, double y) parameterized Point
constructor the constructor initialize the x-coordinate to x and the
y-coordinate to y |
