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!!

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.

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…

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

Tools
• Tips:
– For most school projects, Eclipse should meet
your needs.
– Many other tools can be integrated with Eclipse in
form of plugins.

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.

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.

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.
