Violet UML is an open source UML tool plug-in that extends the functionality of Eclipse to enable the easy creation of simple UML diagrams. Eclipse is a cross-platform, open source, IDE (integrated development environment). The purpose of this tutorial is to guide users in creating UML diagrams with the Violet UML plug-in for the Eclipse IDE.

Further revised by Tim Wood 2018 and Roxana Leontie 2020.COM1012 - System Analysis and Design - Violet UML Tutorial COM1012 - System Analysis and Design - Violet UML Tutorial (no keyword) - accessible within the package.protected - accessible in the class, subclass, and package.private - only accessible within the same class.public - callable, readable/writable by anyone.Refer to the prior set of slides for a reminder of static variables and how they are accessible.Įxercise 2.5: Answer Question 1 on the worksheet. The book defers discussion of protected and no keyword (also called “default”) permission level, but they are simple enough from these slides that you should memorize all of them. Once you do this, try some of the listed extensions.īe sure you have read Head First Java Chapter 7 to learn more about Inheritance and Visibility.Įxercise 2.4: Extend your program to define multiple types of vehicles or objects with inheritance. To compile multiple classes use javac *.javaĮxercise 2.3: Modify your program so it can create 3 cars at random positions and show them driving around.Use the provided pseudocode to guide your for loop.
Modify the RaceTrack class so that it is only responsible for instantiating a car object and then printing it to the screen.Defining a Car class that represents the location of a car.Moving the constants related to printing into the Terminal class.You must turn this into an OOP program by: The RaceTrack.java file starts out identical to the procedural SimpleTrack.java file from the prior exercise.

strongly recommended to do this on terminal to be able to see the actual colors of cars (will not show colors in eclipse)Įxercise 2.2: Modularize the code in the oop/ directory. Try to modify the code as indicated in the slide. Compile the code with javac SimpleTrack.java and run it with java -cp. The slides are broken up into sections below, or you can view the entire PDF.Įxercise 2.1: Look at the code in proc/SimpleTrack.java and try to understand how it works. To practice object oriented design thinking.To learn more about objects and inheritance.You do NOT need to submit any of this work… but you should take it just as seriously as normal! Objectives
You should solve all the blue exercise slides, including answering the first part of the worksheet. You must complete sections 1, 2, and 3 below (up to and including Exercise 2.5). A good other option is ĭeadline: Wednesday 10/28, before class.
