 On Day 1, “Java 2 Micro Edition: The Big Picture,” you see the “big picture” of J2ME by learning about the relationship between J2ME and other wireless technologies.On Day 2, “Assembling a J2ME Development Kit,” you assemble a J2ME development kit by installing Sun’s J2ME Wireless Toolkit. On Day 3, “Getting to Know the J2ME Emulator,” you learn that it isn’t necessary to have a physical mobile device in order to build and test J2ME applications. On Day 4, “Building Your First MIDlet,” you are officially introduced to MIDlets, which are the J2ME equivalents of Java applets. On Day 5, “Working within the CLDC and MIDP APIs,” you spend some time getting acquainted with the two APIs that are used to construct MIDlets: the CLDC and MIDP APIs. On Day 6, “Creating Custom Device Profiles,” wraps up this part of the book with an interesting twist by showing you how to create and use custom device profiles within the Motorola J2ME emulator. On Day 7, “Building Graphical MIDlets,” starts this part of the book off with a bang by guiding you through the graphical portion of the MIDP API, which is used to draw Graphics in MIDlets. On Day 8, “Making the Most of MIDlet GUIs,” you go on a whirlwind tour of MIDP graphical user interfaces (GUIs), and the various classes and interfaces that are involved in creating them. On Day 9, “Exploring MIDlet I/O and Networking,” you are introduced to networking as it applies to wireless mobile devices. On Day 10, “Being Your Own Wireless Meteorologist,” represents a shift in the book toward extreme practicality by guiding you through the development of a MIDlet that retrieves live weather conditions for a user-specified city. On Day 11, “Wireless Navigation,” continues in the spirit of Day 10 by stepping you through the creation of a MIDlet that provides detailed driving directions between two user-specified cities. On Day 12, “Optimizing MIDlet Code,” completes Part II by explaining some of the limitations of MIDP devices and how they impact the performance of MIDlets. On Day 13, “Using the MIDP Record Management System (RMS),” introduces you to the MIDP Record Management System (RMS), which provides a simple means of storing persistent MIDlet data. On Day 14, “Staying in Touch with Your Contacts,” you put your newfound RMS knowledge to good use by building a contact manager MIDlet that enables you to keep track of personal and business contacts. On Day 15, “Managing Your Finances,” you build a personal finance MIDlet that enables you to enter financial transactions. This MIDlet functions somewhat as an electronic check register, which is something many of us could use to help keep from losing receipts while on the go. On Day 16, “Bidding on the Go,” continues with another financial MIDlet by leading through the development of an auction MIDlet. With this MIDlet you can keep track of auctions from the convenience of your mobile phone or pager. On Day 17, “Creating Animated MIDlets,” introduces sprite animation and how it is implemented using the MIDP API. Sprite animation forms the basis for many video games, so you will probably find the code in this lesson to be highly reusable in your own MIDlets. On Day 18, “An Ode to Pong: Creating MIDlet Games,” the sprite code from Day 17 is put to use in a working game that is roughly similar to the classic Frogger game. On Day 19, “The Next Level of MIDlet Gaming,” takes you a step further into the realm of gaming by leading you through the design and development of a strategy game including a computer opponent that relies on artificial intelligence to attempt to outwit you. Part V, “Exploring J2ME Wireless Technologies,” wraps up the book by exploring the present and future of J2ME devices and related technologies: On Day 20, “A J2ME Wireless Tour,” provides a tour of the current crop of wireless mobile J2ME devices and applications. These are the devices that you’ll likely be targeting with your MIDlet development, and the applications that you might be interested in trying out as a mobile device user. On Day 21, “The Future of J2ME,” peers into the crystal ball and assesses the role of J2ME in other types of devices and future mobile technologies. This lesson is intended to help you think about the future and how it will impact J2ME and wireless mobile devices. Download free pdf ebooks of J2ME: Teach Yourself Wireless Java With J2ME in 21 Days
