1 Java the UML Way: Integrating Object-Oriented Design and Programming by Else Lervik and Vegard B. Havdal ISBN John Wiley & Sons, Ltd. Table of Contents Preface xi 1 Introduction Preliminaries for Reading This Book Contemplating a Computer Java Applications and Java Applets JavaScript and JSP How This Book is Structured A Small Example Program Examples of Applets New Concepts in This Chapter Review Problems Programming Problems 20 2 Variables, Data Types, and Expressions Example Data and Variables Algorithms, Programming Errors, and Test Data Statements, Blocks, and Names Variables and Constants Data Types Assignments and Mathematical Expressions Type Conversion Calculations for Our Renovation Project New Concepts in This Chapter Review Problems Programming Problems 49 3 Using Ready-Made Classes Objects as Models of Reality Using Ready-Made Classes The Random Class The String Class Organizing Classes in Packages Class Methods and Class Constants in the Java Library Reading Data from the User New Concepts in This Chapter Review Problems Programming Problems 79 4 Constructing Your Own Classes Creating Classes 82 1

2 4.2 Programming a Class Access Modifiers Private and Public Contents of a Class One More Class and Some New Operators Introduction to Applets Introduction to Graphics New Concepts in This Chapter Review Problems Programming Problems Selection as a Control Structure A Simple Calculator A Selection is a Control Structure Blocks inside Methods The if Statement Nested if and Multiple-Choice Statements Boolean Expressions The Multiple-Choice Statement switch Comparing Computed Decimal Numerals The Conditional Operator?: New Concepts in This Chapter Review Problems Programming Problems Loops as a Control Structure Counter-Controlled Loops A Loop with a General Condition A Graphics Example The for Statement Nested Control Structures The do-while Statement Choosing the Right Loop Statement Controlling Input Data New Concepts in This Chapter Review Problems Programming Problems Collaboration Between Objects Examples of Collaboration Between Objects A Menu-Driven Program Several References to the Same Object Summary: Argument Transfer New Concepts in This Chapter Review Problems Programming Problems Java Libraries and Exception Handling The Online API Documentation Making Your Own Libraries Localization 214 2

3 8.4 Sound and Images Introduction to Exception Handling Exception Handling in Detail New Concepts in This Chapter Review Problems Programming Problems Arrays of Primitive Data Types What is an Array? Copying Arrays The Month Class for Precipitation Data Sorting Searching The java.util.arrays Class Two-Dimensional Arrays More Than Two Dimensions Multidimensional Arrays and Object-Oriented Programming New Concepts in This Chapter Review Problems Programming Problems Arrays of Reference Types and Array Lists An Array of Reference Type Array Lists Wrapper Classes Integer, Double, etc The Methods equals() and tostring() Associations A Bigger Example The Comparable and Comparator Interfaces Sorting Arrays and Array Lists New Concepts in This Chapter Review Problems Programming Problems Using Data Files and Streams Data Files and Streams An Example of a Data File Reading Text from a File Writing Text to a File Data Files: Summary and Class Descriptions Reading Numbers from a Data File Communication with the Console Binary Transfer of Data Random Access to the Contents of a File Serialization New Concepts in This Chapter Review Problems Programming Problems Inheritance and Polymorphism Generalization and Specialization 340 3

4 12.2 Inheritance The Material Class with Subclasses Handling Instances of Subclasses as a Whole The Renovation Example with Many Surfaces and Many Materials What if Polymorphism Didn t Exist? The protected Access Modifier Two Levels of Inheritance Rules and Syntax Interface New Concepts in This Chapter Review Problems Programming Problems GUI Programming and Events GUI Components Pushing a Button Inner Classes Managing the Layout New Concepts in This Chapter Review Problems Programming Problems Texts, Choices, and Windows Text Components and Focus Listeners Giving the User a Choice Between Alternatives Choices Using Check Boxes Choices Using Radio Buttons Choices Using Lists Windows Making a Window Differences Between Applets and Applications Other Ways to Program Listeners New Concepts in This Chapter Review Problems Programming Problems Creating User Interfaces Menus Toolbars Dialog Windows GridBagLayout as Layout Manager The Table GUI Component (the JTable Class) GUI for the Renovation Project New Concepts in This Chapter Review Problems Programming Problems Threads Threads in Processes Dividing Time Between Threads Example of Threads in Use 503 4

5 16.4 Thread Conditions Communication Between Threads Locks and Synchronization More Control: wait(), notify(), and notifyall() Peeking at the Threads with JDB New Concepts in This Chapter Review Problems Programming Problem Data Structures and Algorithms Graphs Lists The Solution: Collection, List, and LinkedList Queues and Stacks Recursion Trees Trees in the API Hashtables New Concepts in This Chapter Review Problems Programming Problems More about Applets What Applets Do on the Web Security Programming an Applet Security in Practice Communication Between Applet and Browser New Concepts in This Chapter Review Problems Programming Problems Distributed Systems with Socket Programming and RMI Sockets Objects That Collaborate over a Network How Does Communication Between the Objects Occur? RMI and Applets Deployment Diagram A Distributed System with Callback New Concepts in This Chapter Review Problems Programming Problems Programming with Databases Database Drivers Establishing Contact with a Database A Bigger Example A Database Application The Three-Layer Architecture Transactions and Compiled SQL Statements New Concepts in This Chapter 645 5
