- 6. Computing before Java Operating System Hardware Compile Executable C or Fortran Source Link Relocatable Platform
- 7. To Port Source code • Some times the source code is portable – One source can be compiled on different systems – different flavors of Unix • But, need to compile and test separately for each supported platform

- 11. Java: Portable code • Executable portable browser code: Applet > Stored on Server > Executed on Client Browser • Implications > Platform Independent > Revolution in Software Distribution
- 12. Sun announces Java and HotJava at SunWorld '95. Netscape announces its intention to license Java for use in Netscape browser.
- 13. Why did Java become Popular • Familiar & Simple – like C, C++ • Object-Oriented language • Portable - > executes anywhere Java Virtual Machine exists • Robust, Secure • Garbage Collection – No memory leaks • Distributed > Network Ready
- 14. Java: Desktop Client Platform • Java code executes anywhere JVM exists > Browser > Operating System > Chip • Implications > Write it once, Run it anywhere > The language itself is the platform!

- 41. What's an IDE? Integrated Development Environment - a set of tools that aid application development
- 42. Why Do I Care? Because IDEs eliminate the tedious parts of coding, allowing you to focus on solving the problem.
- 43. How So? • By being aware of your code syntax • By showing errors as you type
- 44. How So? • By understanding the Java APIs, even the one's you create
- 45. How So? • By: >Compiling your code >Automating repetitive tasks >Automatically creating classes, methods and properties >Providing an interactive debugger >Refactoring your code >Integrating with source code repositories >Integrating with application servers
- 46. What is NetBeans? • Free Open Source Pure JavaTM IDE • Modular and Extensible • Supports things you have to pay for in other IDEs http://www.netbeans.org
- 48. NetBeans History • Started in 1996 as a student project at Charles Univeristy in Prague (originally called Xelfi) • Most of these same students (now Sun employees) are still working on NetBeans today.
- 49. NetBeans History • The original plan was to develop network-enabled JavaBeans, hence the name NetBeans. • In 1999, Sun acquired NetBeans, and briefly renamed it “Forte for Java” • In 2000, Sun open sourced NetBeans. > Although a large contributor to open source projects, NetBeans was Sun's first sponsored project. > netbeans.org web site was launched • In 2001, The Platform was born > A generic desktop application suitable for any purpose
- 50. NetBeans 4.1 – It Just Works • Intuitive User Interface & Usability • Supports the latest Java APIs (5.0) • Your Ant script is your project • Unit testing – a natural part of development • Integrated CPU & Memory Profiler • J2ME Mobility Support • J2EE & Web Services Support D e m o
