Description

This is a simple console drawing program in Java.

The program works as follows:

Below is a sample run of the program. User input is prefixed with enter command:

enter command: C 20 4 -------------------- | | | | | | | | -------------------- enter command: L 1 2 6 2 -------------------- | | |xxxxxx | | | | | -------------------- enter command: L 6 3 6 4 -------------------- | | |xxxxxx | | x | | x | -------------------- enter command: R 14 1 18 3 -------------------- | xxxxx| |xxxxxx x x| | x xxxxx| | x | -------------------- enter command: B 10 3 o -------------------- |oooooooooooooxxxxx| |xxxxxxooooooox x| | xoooooooxxxxx| | xoooooooooooo| -------------------- enter command: L 6 4 13 4 -------------------- |oooooooooooooxxxxx| |xxxxxxooooooox x| | xoooooooxxxxx| | xxxxxxxxooooo| -------------------- enter command: B 1 2 . -------------------- |oooooooooooooxxxxx| |. ooooooox x| | .oooooooxxxxx| | . ooooo| -------------------- enter command: Q 

Build To build the executable Jar, run the following maven command in the project root directory: $ mvn clean package

A simple, fun program to draw on console.

The program was built using Java 8 and Maven

Command Description C w h Create a new canvas of width w and height h. L x1 y1 x2 y2 Create a new line of 'x' from (x1,y1) to (x2,y2). Only support horizontal or vertical lines. R x1 y1 x2 y2 Create a new rectangle, (x1,y1) is upper left corner & (x2,y2) is lower right corner. B x y c Fill the entire area around (x,y) with "colour" c. Same as that of the "bucket fill" tool in paint programs. Q Quit. 

enter command: C 20 4 ---------------------- | | | | | | | | ---------------------- enter command: L 1 2 6 2 ---------------------- | | |xxxxxx | | | | | ---------------------- enter command: L 6 3 6 4 ---------------------- | | |xxxxxx | | x | | x | ---------------------- enter command: R 14 1 18 3 ---------------------- | xxxxx | |xxxxxx x x | | x xxxxx | | x | ---------------------- enter command: B 10 3 o ---------------------- |oooooooooooooxxxxxoo| |xxxxxxooooooox xoo| | xoooooooxxxxxoo| | xoooooooooooooo| ----------------------

  Console Drawing Board

  A drawing board is a kind of desk which can be used for any kind of drawing, writing or sketching on a sheet of paper. This program, console drawing board, is a Java program that provide a console interface and enable you to draw several figures, including rectangles and triangles.

  Prerequisite

  Program Structure

  1. BufferReader (br) which is reponsible for taking inputs from the user with readLine function
  2. String (in) which is the input string
  3. PrintWriter (pw) which prints program messages
  4. ScreenManager (sm) which manages and plots the figures of the drawing board
  1. Drawing: the user can draw a rectangle by specifying the width, height, the center of x, and the center of y or a triangle by providing the three vertices.
  2. Erasing: the user can erase any drawn figure.
  3. Centering: the user can center any drawn figure.
  4. Example: there is a robot thread that trigger key board events to show the exmaple usage of this program.
  5. Exit: exit this program

   sm.printScreen(); while (true)  pw.printf("Welcome to the drawing board !\n1.draw\n2.erase\n3.center\n4.example\n5.exit : "); try  in = br.readLine(); if (in.equals("5")) break; > catch (IOException e)  e.printStackTrace(); continue; > switch (in)  case "1": draw(); break; case "2": erase(); break; case "3": center(); break; case "4": example(); break; default: pw.printf("Wrong entry number : %s\n", in); break; > >

  ScreenManager keeps the information of the drawn Figure in an ArrayList fgs on the drawing board and the information of the grid in an array db with the size of 50 * 50.

  public class ScreenManager  public ScreenManager()  pw = new PrintWriter(System.out, true); db = new int[2500]; fgs = new ArrayListFigure>(); > public void draw(int x,int y) db[x+50*y]++; > public void erase(int x,int y) db[x+50*y]--; > public void addFig(Figure fg) fgs.add(fg); fg.draw(this); > public void delFig(Figure fg) fgs.remove(fg); fg.erase(this); > public ArrayListFigure> getFigList() return fgs; > public void printScreen()  pw.print('+'); for (int i = 0;i50;i++)pw.print((char)('-'+65248)); pw.println('+'); for (int i = 0; i  db.length; i++)  if(i%50==0)pw.print('|'); if(db[i]>0)pw.print((char)('*'+65248)); else pw.print((char)12288); if ((i+1)%50==0) pw.println('|'); > pw.print('+'); for (int i = 0;i50;i++)pw.print((char)('-'+65248)); pw.println('+'); > protected ArrayListFigure> fgs; protected PrintWriter pw; protected int[] db; >

  public abstract class Figure extends Component public Figure() centerPoint = new Point( 0, 0); name = "None"; > public Figure(String n,Point p) centerPoint = new Point(p); name = new String(n); > abstract public void draw(ScreenManager sm); abstract public void erase(ScreenManager sm); abstract public void center(ScreenManager sm); abstract public void showDetail(PrintWriter pw); public String getName() return name; > protected Point centerPoint; protected String name; /** * */ private static final long serialVersionUID = 1L; >

  Demonstration

  Conclusion

  This simple console board drawing program can provide a basic template for more sophisticated console plotting program.

  Console Drawing Java Application

  This is Shape Drawing Application for Console, developed in java and SpringBoot Framework. It is developed with MVC design pattern At this time, the functionality of the program is quite limited but this might change in the future. In a nutshell, the program should work as follows:

  1. Create a new canvas
  2. Start drawing on the canvas by issuing various commands
  3. Quit

  Please follow below instructions to get a copy of the project up and running on your local machine for development and testing purposes.

  1. Java/JDK version 1.8 or above should be installed in local machine.
  2. If Porject needs to be cloned from github then Git needs to insatlled in local machine.
  3. To review the Code, any Java development IDE is recommended to installed in local machine.
  4. For running the application code or Test Module via command Line, Mavan needs to installed in you local Machine.
  5. Application and Test module can be executed from development IDE as well
  1. As per Requirements, commands for action should always be given in CAPS
  2. As per Requirements, Diagnol Lines are not allowed to be made.
  3. Bucket Fill for already painted shape is not considered.

  A step by step series of examples that tell you how to get a development env running

  1. Clone the project from gitHub repository GitHub Link
  2. Copy/Download the zip Project from Dropbox [DropBox Link] (https://www.dropbox.com/s/2rmqkrffhwybw9e/AnandPratapSingh.zip?dl=0)
  3. Open Developemt IDE for Code Review and Run, Import «Exisitng Maven Project» into your local workspace.

  1. From Command Line: Go to Project root folder--> Run "mvn test" 2. From IDE: Select Mavan Build/Run config, select Project root as Base Directory. Set goal as "test". Click on Run(Assumption, JRE is configured correctly) 3. From IDE: Select "/consoleDrawing/src/test/java" and run as Junit Test. 

  1. From Command Line: Go to Project /consoleDrawing/target folder--> Run java -jar consoleDrawing-1.0.jar 2. From IDE: Select Mavan Build/Run config, select Project root as Base Directory. Set goal as "exec:java". Click on Run(Assumption, JRE is configured correctly) 3. From IDE: Select "/consoleDrawing/" and run as Java application. 

  Below is a sample run of the program. User input is prefixed with enter command: Choose Options: C L R B Q C 20 4 ---------------------- | | | | | | | | ---------------------- L 1 2 6 2 ---------------------- | | |xxxxxx | | | | | ---------------------- L 6 3 6 4 ---------------------- | | |xxxxxx | | x | | x | ---------------------- R 14 1 18 3 ---------------------- | xxxxx | |xxxxxx x x | | x xxxxx | | x | ---------------------- B 10 3 o ---------------------- |oooooooooooooxxxxxoo| |xxxxxxooooooox xoo| | xoooooooxxxxxoo| | xoooooooooooooo| ---------------------- Q Thank You For Using Drawing Console 

  Development Style and Design Pattern Used

  1. TDD Basic development approach was followed.
  2. SpringBoot is used to developer core framework
  3. MVC Design Pattern is followed Controller: DrawingBaseController.java View: DrawingConsoleView.java Model: CanvasModel.java
  4. To Loose coupling and high cohesion, Factory pattern is used to generate Service based on Command selected. DrawingService.java -> Interface ShapeBuilderServiceFactory.java —> Service Factory DrawBlankCanvasServiceImpl.java,DrawLineServiceImpl.java,DrawRectangleServiceImpl.java,FillBucketServiceImpl.java —> Implemenation
