Early Beginnings (1990-1995) |
-
1990 : Thre Green Project
-
Sun Microsystems, led by James Gosling, Mike Sheridan,
and Patrick Naughton initiated the
"Green Project" to explore the possibilities of
consumer electronics
and digital devices.
-
The aim was to create a language for programming home appliances
like TVs, VCRs, and other electronic devices.
-
The team initially considered using C++, but they found it too
complex and unsuitable for embedded systems. This led them to create
a new language that was simple, platform-independent, and secure.
-
1991 : Birth Of Oak
-
James Gosling began work on a new language called "Oak," named after
an oak tree outside his office.
-
Oak was designed to be simple, secure, and platform-independent,
focusing on portability and reliability for embedded systems.
-
The Green Project team created a device called "Star7", an
interactive, handheld home-entertainment controller, to showcase
Oak's capabilities, but it failed to gain traction in the consumer
electronics
market.
-
1992 : The Green Project's First Success
-
The Green Project team developed the "Star7," a handheld device
controller with a graphical user interface that demonstrated Oak's
capabilities.
-
However, the project faced challenges due to the slow adoption of
digital consumer electronics, leading the team to shift focus.
-
1993 : Shift to the Internet
-
The team realized that the growing World Wide Web presented a new
opportunity for Oak's platform independence.
-
They started adapting Oak for web-based applications, aiming to
create interactive and dynamic web content.

The Birth of java (1994-1995) |
-
1994: Oak Becomes Java
-
Oak was renamed Java, after the team decided that "Oak" was already
trademarked. The name "Java" was chosen after a brainstorming
session where the team discussed many names, ultimately settling on
one inspired
by Java coffee.
-
The team created the first Java-enabled web browser, "WebRunner,"
later renamed "HotJava."
-
1995 : Official Release of Java 1.0
-
Sun Microsystems officially announced Java 1.0 on May 23, 1995,
at the SunWorld conference.
-
The "Write Once, Run Anywhere" (WORA) capability
became a core feature, allowing Java programs to run on any device
with a Java Virtual Machine (JVM).
-
The release included key components like the Java
Development Kit (JDK), the HotJava
browser , and the Java Runtime Environment
(JRE).
-
1995 : Netscape Integrates Java
-
Netscape Navigator is first web browsers to integrate Java, which
leading a web browser at the time, significantly boosting Java's
visibility and adoption.
-
Java applets (small Java applications that run in a web browser)
gained popularity for creating interactive web content.
-
Java allowing developers to create dynamic and interactive web
content using applets.

Java's Rise to Prominence (1996-2000) |
-
1996 : Java 1.1
-
Java 1.1 was released with significant improvements, including the
addition of inner classes, JavaBeans, JDBC (Java Database
Connectivity), RMI (Remote Method Invocation), Garbage
collection, Security features and Robust set of standard
libraries.
-
This version also introduced the reflection API, allowing for
runtime manipulation of class properties.
-
1997: Java 2 Platform (J2SE 1.2)
-
The release of Java 2 Standard Edition (J2SE 1.2) marked a major
evolution in the platform.
-
Sun Microsystems submitted Java to the ISO/IEC JTC 1, a standards
organization, to solidify its position as an open standard.
-
This was an important move that helped Java gain further adoption in
the enterprise world by ensuring its long-term availability and
platform independence.
-
Java 2 introduced the Swing graphical user interface (GUI)
toolkit, the Collections Framework, and theem
"HotSpot" JVM for improved performance.
-
The Java platform was rebranded into three editions:
J2SE (Standard Edition) :
For desktop and general-purpose development.
J2EE (Enterprise Edition) :
For large-scale, distributed, and enterprise applications.
J2ME (Micro Edition) :
For resource-constrained devices such as mobile phones and embedded systems.
-
1998: Java Enterprise Edition (J2EE)
-
Java 2 Enterprise Edition (J2EE) was introduced, focusing on
large-scale, distributed enterprise applications.
-
J2EE included technologies such as Servlets, JSP (JavaServer Pages),
and EJB (Enterprise JavaBeans), enabling robust server-side
applications.
-
The Swing library was introduced in J2SE, providing a more flexible
way to build graphical user interfaces (GUIs).
-
1999: Java Community Process (JCP) & JavaServer Pages (JSP)
-
Sun Microsystems established the Java Community Process (JCP) to
formalize the process of defining new Java specifications.
-
The introduction of JavaServer Pages (JSP) and Servlets transformed
web development in Java.
-
JSP allowed for dynamic content generation on web pages, similar to
technologies like PHP or ASP, while Servlets made it easier to
handle HTTP requests in Java web applications.
-
The JCP allowed stakeholders, including developers and companies, to
contribute to the evolution of the Java platform.
