This paper describes how to model the dynamic aspects of software systems using
UML notation and semantics. The three topics covered are sequence diagrams, activity
diagrams and state charts. An explanation is given of each and how they fit into the
overall model structure.
Introduction to java programming: Chapter 7 - Objects and Classes's Objectives is to understand objects and classes and use classes to model objects; learn how to declare a class and how to create an object of a class; understand the roles of constructors and use constructors to create objects; use UML graphical notations to describe classes and object.
This book aims to instil the reader with an understanding of the Object Oriented approach to
programming and aims to develop some practical skills along the way. These practical skills will
be developed by small exercises that the reader will be invited to undertake and the feedback that
will be provided.
The concepts that will be explained and skills developed are in common use among programmers
using many modern object oriented languages and are thus transferrable from one language to another.
The major changes to this Fourth Edition include an earlier introduction to UML, a new
section on inter-file communication in Chapter 13, and a revised approach to software development
in Chapter 16.
Introducing the UML at the beginning allows the use of UML diagrams where they fit
naturally with topics in the text, so there are many new UML diagrams throughout the book.
The section on inter-file communication gathers together many concepts that were previously
scattered throughout the book.
Functional and flexible, this guide takes an objects-first approach to Java programming and problem using games and puzzles. Updated to cover Java version 1.5 features, such as generic types, enumerated types, and the Scanner class. Offers independent introductions to both a command-line interface and a graphical user interface (GUI). Features coverage of Unified Modeling Language (UML), the industry-standard, object-oriented design tool. Illustrates key aspects of Java with a collection of game and puzzle examples.
