3. Where we were?
In June 1991:
James Gosling starts working
on an interpreter (called "Oak"),
which, several years later is
renamed "Java."

4. Where we were?
In August 1991:
- A small group of Sun engineers called the
"Green Team“, led by James Gosling,
demonstrates basic user interface ideas and
graphics system to Suns co-founders
- They believed that the
next wave in computing
was the union of digital
consumer devices and
computers

5. Where we were?
From 1991 to 1995:
Events & evolution such as:
- Mosaic 1.0, the first graphical browser for
the Internet, is released
- Interactive Cable TV
- Java compiler in Java has been
implemented (James had previously
implemented it in C)
- Java compatible browsers (Netscape)

6. Where we were?
From 1991 to 1995:
This concept was too much advanced for the
industry at the time BUT it was just right for
the Internet, which was just starting to take
off. In 1995, the team announced that the
Netscape Navigator Internet browser would
integrate with Java technology.

7. Where we were?
So:
- The first programming language was created,
a cross-platform computing environment NOT
tied to any particular operating system or
microprocessor!
- Applications written in Java will run anywhere
- Eliminating incompatibility between operating
systems and versions of operating systems.

9. Where we were?
Java Technology consists of:
- Java Language: used to develop software
for mobile devices, browser-run applets,
games, desktop, enterprise (server-side), and
scientific applications
- Java Platform: consists of Java Virtual
Machine (JVM) responsible for hardware
abstraction
- Java Tools: like java compiler

10. Where we were?
Java Development Kit 1.0 was released on
January 23, 1996
JDK API

11. Where we were?
JDK releases:
- 1995 Alpha & Beta
- 1996 JDK 1.0 > Basic support for AWT
- 1997 JDK 1.1 > JavaBeans, RMI, AWT,
JDBC, servlets, JNDI, EJB
- 1998 Java 1.2 > Reflection, Swing, Java
Collections Framework, plug-in, …
Becomes known as Java 2, Port to Linux.

12. Where we were?

Candidate

13. Where we are?
- 9 Million Java Developers Worldwide

- 3 Billion Mobile Phones Run Java
- 100 Percent of Blu-ray Disc Players Ship with Java

- 5 Billion Java Cards in use
- 7 Billion Java Cards sold
- 89% of desktops run java
- 125 million TV devices run java

14. Where we are?
Also Many embedded devices are based on Java:
set-top boxes, printers, web cams, games, car
navigation systems, lottery terminals, medical
devices, parking payment stations, etc

15. Where we are?
- Java is not a new programming language any more.
- From early 1995 until now we have seen how it has
developed from a JDK (Java Development Kit) to
Java EE (Enterprise Edition) and new Java Open
Source frameworks and technologies.
- At the beginning, Java was about a few packages
and APIs you could use to solve small problems. But,
what about now, when Java has branched out into
several technologies and Open Source frameworks?

16. Where we are?
There are four Java Platforms:
1) Java Standard Edition (Java SE)
2) Java Enterprise Edition (Java EE)
3) Java Micro Edition (Java ME)
4) JavaFX
ME
SE
EE
JavaFX

17. Where we are?

18. Where we are? Java SE

19. Where we are? Java EE
Built on top of the Java SE
platform, for developing
and running large-scale,
multi-tiered, scalable,
reliable, and secure
network applications

20. Where we are? Java ME
- APIs & small virtual machine for running
java programming language applications on
small devices, like mobile phones.
- A subset of the JavaSE
API
- Java ME applications
are often clients of Java
EE platform services

21. Where we are?
Java FX: a platform for creating rich internet
applications using a lightweight user-interface
API

28. Where we’re going? Open Source
New languages build on JVM

29. Where we’re going? Open Source
New languages build on JVM
Why Scala over Java:
- Increased productivity due to reduced
verbosity
- Developers can mix and match
imperative and functional programming
paradigms as needed
- Built-in functionality for parallelism and
concurrency

30. Where we’re going? Open Source
New languages build on JVM

31. Where we’re going? Open Source
New languages build on JVM

32. Opportunity or concerns
Now, we have a problem to solve:
“there are too many choices”
How do we select now?
- Opportunity?
- Concern?

33. SW Engineering
Many factors are involved in SW engineering!

34. Know how!
- Usability: focusing on end users
- Focusing on problems: not technologies, tools
and platforms, select the easiest ones
- Be realistic: obtainable competence
- Make a list of what is important for your
Software lifecycle. Identify/prioritize them &
then select
- You can change your mind: most of your
technology choices can change

35. Know how!
- Easy & Quick: select a SW that you know to
be easier and quicker to prototype.
- Standard vs. Open Source: check the open
source products licenses.
Open Source != Free Software
- Start with capabilities, not implementations
- Cost: consider the total cost
- Involve your team early
- Testing and deployment: software that makes
testing difficult should be avoided

36. Know how!
- Avoid Lock-in: e.g. if SW has limitation, runs
on a certain Operative System or environment
- New versus existing software: reuse
