Points and Lines

Computer graphics systems make use of two general rendering systems rasters and vectors -- to produce images. Raster systems keep track of collections of individual pixels and vector systems keep track of lines. (Lines are more accurate, but require more computer resources.)

This assignment calls for a Line object that represents a graphically depicted image on the screen. This object must store this data:

Endpoint objects (x and y coordinates as an integer). There will be two of these.

The line color as a String

The line width as an integer

Note that the Line object must be composed of two Point objects.

The Point Class

Create a Point class that contains x and y coordinates (x and y are integers) that represents a point in two-dimensional space. A point can lie only in the first quadrant in the x-y coordinate axis. Include the following methods

two constructors: a default that initializes x and y to 0, and another that accepts the x and y values as passed-in parameters

get and set methods to retrieve and assign coordinate values

a toString method that will return a String containing the coordinates of the point formatted as (x, y) an equals method (returns a boolean value) that compares two Points for equality. This method takes a single parameter of type Object and will cast the Object into a Point for comparison. anything else you deem necessary

The Line Class

Create a Line class that contains variables and/or methods to represent

the end Points of the line (be sure your Point objects are declared as private)

the length of the line (represent this as a return value from a method)

color

width

This Line class should have the following methods

A default constructor that creates Points that represent a zero-length black line at the origin with a width of 1 pixel

A constructor that accepts four ints x and y for point 1 and x and y for point 2, a color and a width A constructor that accepts four ints (color defaults to black and width to 1 pixel)

get and set methods to retrieve values and assign values as you deem necessary

A toString method that prints the coordinates of the line endpoints, the length, the color and width of the line (nicely formatted, please)

an equals method (returns a boolean value) that will compare two lines for equality. Two lines are equal if their endpoints, width and color are the same. Note that Points do not need to be in same order. Be sure and use the equals method you wrote from your Point class to compare Points. Your equals method should override the equals method in Object.

a validateLine method that will make sure the points are in the first quadrant. This method must be declared as static -- so that it can be called without an instance of the class.

Create a driver class called LineDriver that will work with two lines. Create both lines as zero-length at the origin. Then provide a menu that is displayed repetitively with the following options:

1 - Enter coordinates, width and color for first line (line should be validated as part of this process -- use the validateLine method -- do not continue until valid coordinates and width are obtained from the user)

2 - Enter coordinates, width and color for second line (ditto)

3 - Compare the two lines (specify if lines are equal/not equal after comparison)

4 - Display coordinates, width, length and color for first line (the length should be derived from the coordinates using the distance formula and is represented as a real number with 2 post-decimal positions of precision.)

5 - Display coordinates, width, length and color for second line (the length should be derived from the coordinates using the distance formula and is represented as a real number with 2 post-decimal positions of precision.)

6 - Quit
