  • Programming Java for OS X
    Programming Java for OS X hat’s so different about Java on a Mac? Pure Java applica- tions run on any operating system that supports Java. W Popular Java tools run on OS X. From the developer’s point of view, Java is Java, no matter where it runs. Users do not agree. To an OS X user, pure Java applications that ignore the feel and features of OS X are less desirable, meaning the customers will take their money elsewhere. Fewer sales translates into unhappy managers and all the awkwardness that follows. In this book, I show how to build GUIs that feel and behave like OS X users expect them to behave. I explain development tools and libraries found on the Mac. I explore bundling of Java applications for deployment on OS X. I also discuss interfacing Java with other languages commonly used on the Mac. This chapter is about the background and basics of Java develop- ment on OS X. I explain the history of Java development. I show you around Apple’s developer Web site. Finally, I go over the IDEs commonly used for Java development on the Mac. In This Chapter Reviewing Apple Java History Exploring the history of Apple embraced Java technologies long before the first version of Java on Apple computers OS X graced a blue and white Mac tower. Refugees from the old Installing developer tan Macs of the 1990s may vaguely remember using what was tools on OS X called the MRJ when their PC counterparts were busy using JVMs. Looking at the MRJ stands for Mac OS Runtime for Java.

It also describes the application programming interface with applets and swings. This paper explains about the java and its connectivity with database. It describes the structured query language as a data definition and data manipulation language. It also defines the java platform. 1. INTRODUCTION Java is a high-level object-oriented programming language developed by the Sun Microsystems. Though it is associated with the World Wide Web but it is older than the origin of Web. It was only developed keeping in mind the consumer electronics and communication equipment’s. It came into existence as a part of web application, web services and a platform independent programming language in the 1990s. Earlier, C++ was widely used to write object oriented programming languages, however, it was not a platform independent and needed to be recompiled for each different CPUs.

  • The GNOME Desktop Environment
    The GNOME desktop environment Miguel de Icaza ([email protected]) Instituto de Ciencias Nucleares, UNAM Elliot Lee ([email protected]) Federico Mena ([email protected]) Instituto de Ciencias Nucleares, UNAM Tom Tromey ([email protected]) April 27, 1998 Abstract We present an overview of the free GNU Network Object Model Environment (GNOME). GNOME is a suite of X11 GUI applications that provides joy to users and hackers alike. It has been designed for extensibility and automation by using CORBA and scripting languages throughout the code. GNOME is licensed under the terms of the GNU GPL and the GNU LGPL and has been developed on the Internet by a loosely-coupled team of programmers. 1 Motivation Free operating systems1 are excellent at providing server-class services, and so are often the ideal choice for a server machine. However, the lack of a consistent user interface and of consumer-targeted applications has prevented free operating systems from reaching the vast majority of users — the desktop users. As such, the benefits of free software have only been enjoyed by the technically savvy computer user community. Most users are still locked into proprietary solutions for their desktop environments. By using GNOME, free operating systems will have a complete, user-friendly desktop which will provide users with powerful and easy-to-use graphical applications. Many people have suggested that the cause for the lack of free user-oriented appli- cations is that these do not provide enough excitement to hackers, as opposed to system- level programming. Since most of the GNOME code had to be written by hackers, we kept them happy: the magic recipe here is to design GNOME around an adrenaline response by trying to use exciting models and ideas in the applications.

  • The Applet Class, Swings

No Java AWT Java Swings 1 AWT stands for Abstract windows Swing is also called as JFC’s (Java toolkit. Foundation classes). 2 AWT components are platform- Java swing components are platform- dependent. independent. 3 AWT components are heavyweight. Swing components are lightweight. 4 AWT doesn't support pluggable look Swing supports pluggable look and and feel. feel. Sl. No Java AWT Java Swings 5 AWT provides less components than Swing provides more powerful Swing. components such as tables, lists, scrollpanes, colorchooser, tabbedpane etc. 6 AWT doesn't follows MVC(Model View Swing follows MVC. Controller) where model represents data, view represents presentation and controller acts as an interface between model and view. Two Key Swing Features (June 2012, 10m) 1. Lightweight components 2. Pluggable look and feel 1. Lightweight Components Swing components are lightweight as they are written entirely in Java and do not depend on native peers (platform specific code resources). Rather, they use simple drawing primitives to render themselves on the screen. The look and the feel of the component is not controlled by the underlying operating system but by Swing itself. Thus, they are not restricted to platform-specific appearance like, rectangular or opaque shape. 2. Pluggable Look and Feel Swing supports a pluggable look and feel (PLAF). Because each Swing component is rendered by Java code rather than by native peers, the look and feel of a component is under the control of Swing.

Chapter 1 Introduction From a developer’s perspective, the APIs for desktop PCs and enterprise systems have been a daunting combination of complexity and confusion. Over the last 10 years, Java™ technology has helped simplify and tame this world for the benefit of everyone. Developers have benefited by seeing their skills become applicable to more systems. Users have benefited from consistent interfaces across different platforms. And systems vendors have benefited by reducing and focusing their R&D investments while attracting more developers. For desktop and enterprise systems, “Write Once, Run Anywhere”™ has been a success. But if the complexities of the desktop and enterprise world seem, well, complex, then the connected device world is even scarier.
