3. Java: History JDK 1.0 (January 23, 1996) JDK 1.1 (February 19, 1997) J2SE 1.2 (December 8, 1998) J2SE 1.3 (May 8, 2000) J2SE 1.4 (February 6, 2002) J2SE 5.0 (September 30, 2004) Java SE 6 (December 11, 2006) Java SE 7 (July 28, 2011) Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

4. Java: History WHY: People were desperate for portable programs which are not hardware and operating system dependent. How: A program, called Java Virtual Machine, is installed to hide details of the operating system and hardware. So: Write once, Run anywhere!! Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

5. Java: Applications Ranked #1 (2011) and #2 (2012) in the most popular programming languages. (tiobe.com) Android applications are all written in Java. Hadoop, the most popular framework for managing cloud, was written in Java. Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

6. Java Development Kit (JDK) Provides Java programmer with numerous classes and methods for – Developing Graphical User Interfaces (GUI) – Data processing – Multithreaded programs – Networking programs – Many more… Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

7. Tools Many open source tools exist for developing Java based projects – Integrated Development Environment: Eclipse, NetBeans – Unit Testing: JUnit – Configuration Management: TortoiseSVN – Continuous Build: CruiseControl – Game Development: JMonkeyEngine Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

8. Tools Tips: – For most school projects, Eclipse should meet your needs. – Many other tools can be integrated with Eclipse in form of plugins. Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

9. Demo 1 Hello, World! – How to edit, compile, and execute Java programs in Eclipse. Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

10. Demo 2 Eight-puzzle solver – Basic GUI – Image input and output – Data structures support – Artificial intelligence Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

11. Demo 3 Convex hull finder: – Basic drawing methods – Timer events – Data structure support – Computational geometry Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

12. Demo 4 Road graphics generator – Basic GUI with user inputs – Integration with a game engine Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

13. Demo 5 Multithreaded application RandNumGen Unlimited Size Buffer Data Collector run every 30ms Collects data every 100 ms Disk Internal Buffer Disk...... Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

14. Demo 5 (cont) Do not step on each other’s foot – Data collector shall not read from the unlimited buffer when it is being written. – Random # generator shall not write to the unlimited buffer when it is being read. – Data collector shall not update its internal buffer when not each file saver completes. – No file saver shall save the same content more than once. Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

15. Demo 6 Networked chatter – Basic GUI with user inputs – Socket communication Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

16. C# C# 1.0: December, 2002 C# 2.0: October, 2005 C# 3.0: August, 2007 C# 4.0: April, 2010 Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

17. C# Why Java Programmers Can Learn C# Quick: C# is very similar to Java in syntax. C# programs run on the.NET framework just like Java programs run on the Java Virtual Machine. Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012

18. Tools for C# Programming While other tools exist, Visual Studio is the mostly used tool for C# programming. Visual Studio can be downloaded at https://www.dreamspark.com/ for free to students. Computer Science, Software Engineering & Robotics Workshop, FGCU, April 27-28, 2012
