A simple console drawing application

Steps to start application

1

• Import the code in visual code or any other IDE
• Import the dependencies (pom.xml)
• Start the application (F5)

2

• Import the code in visual code or any other IDE
• Run mvn clean package in command line
• Move to the target folder
• Run java -jar .\console-drawing-app-1.0.jar

Features/ Assumptions

• Canvas has to be created first before we can add any line/rectangle or bucket fill
• Only horizontal and vertical lines can be created
• Only lines within the canvas boundary can be drawn
• Commands are sanitized before implementing (handling of extra spaces at the front and back)
• Shapes can be drawn only if the initial coordinates lie within the canvas boundary
• Detailed test cases are written

Commands
