CMSC 330 Project 1 The first programming project involves extending the Java skeleton program that it is provided in the attached . 21p file. That skeleton program displays a scene of graphic images contained in a scene definition file. The grammar for that scene definition file is shown below: In the above grammar, terminal symbols are upper case names or character literals shown in blue and nonterminal symbols are lower case names shown in red. EBNF metacharacters are shown in black. Tokens can be separated by any number of spaces. Identifiers and keywords are strings of alphabetic characters. Both are case sensitive. Numbers are unsigned integers. That program reads in the scene definition file that defines the image objects in a scene and creates those objects, inserts them into the scene and displays that scene. You are to modify the program so that it will parse and display the additional images defined by the expanded grammar shown below with the additions to the grammar highlighted in yellow: The UML diagram for the whole project is shown below: by writing those classes shown in red and modifying the parser class so that it will parse the expanded grammar. Below is a description of each of the five classes that you must write: The Text class must contain a constructor that is supplied the color that defines the text color, a point that specifies the text location and a string containing the text to be displayed. It must also contain a draw function because it is extends the abstract class Image. The draw function must draw the text using the method drawstring in Graphics class. The solidpolygon class must contain a constructor that is passed the number of vertices in the polygon and its color. It must define the method drawpolygon because it is extends the abstract class Polygon_. It should call the f111polygon method of the Graphics class to draw a solid polygon. The Isoscelestriangle class must have a constructor that is supplied the color of the triangle, a point that specifies the location of the top vertex, and the height and width of the triangle. It must allocate the arrays of x and y coordinates that defines the triangle and it must compute their values. The Parallelogram class must have a constructor that is supplied the color of the parallelogram, two points that specifies the location of the upper left and lower right vertices in addition to an x offset value that specifies the x distance between the upper and lower left vertices. It must allocate the arrays of x and y coordinates that defines the parallelogram and it must compute their values. The Regularpolygon class must contain a constructor that is supplied the color of the polygon, the number of sides, a point that specifies the location of its center, and the radius, which defines the distance between the center and each of the vertices. It must allocate the arrays of x and y coordinates that defines the regular polygon and it must compute their values. Below is a sample of a scene definition file that would provide input to the program: Scene Polygons (500,500) Rightrriangle Color (255,0,0 at (50,30) Height 100 width 300; Rectangle Color (0,128,255) at (100,100) Height 200 width 100; Isosceles Color (255,0,0) at (120,120) Height 100 width 200; Parallelogram Color (0,0,255) at (340,50)(440,120) offet 30 ; Regularpolygon Color (255,0,255) at (300,300) Sides 6 Radius B0; Text Color (0,0,0) at (400,200) "Hello World"; End. Shown below is the scene that should be produced when the program is provided with the above scene definition. The deliverables for this project include the following: 1. A .zip file containing all the source code correctly implementing all required functionality. a. All the . Java files provided in the skeleton should included regardless of whether they required any changes b. All new files must include a header with the student name, date, project and a description of what the file contains c. All modified files must include a header with the same information 2. A Word or PDF file that contains the following: a. A discussion of how you approached the project b. A test plan that contains test cases that include all additional images and test any new functionality. For each test case, the output produced should be included. c. A discussion of lessons learned from the project and any improvements that could be made
