Introduction to Java Technology
Java language, originally called the ‘X’
Oak
Java language was developed by X at X
James
Gosling
Sun Microsystems
Sun Microsystems is now a subsidiary of
Oracle Corporation
Javal language was released in X as a core component of Sun
Microsystems’ Java platform
1995
It has derived much of its syntax from C and C++ but has a simpler
object model and fewer low-level facilities.
java language
is a general-purpose, concurrent, class-based, object-
oriented language that is specifically designed to have as few
implementation dependencies as possible.

files with .java extension
java source code files
java source code files compiles into a format called
bytecode (files with .class extension)
can be executed by a Java interpreter.
bytecode (files with .class extension)
It was intended for use in Sun’s project research to work on a
programming software to control electronic devices
java
It was modified to take advantage of the World Wide Web.
Java
The X, later named as X, was the very first
web browser created in Java.
WebRunner
HotJava
In 1995, the X internet browser was also
developed to support Java.
Netscape Navigator
X is a portable language that could run
on any platform. The language was able to do
this by generating intermediate code for a
hypothetical computer called a virtual machine.
Java
X is a
program that runs on all computers.
Java Virtual Machine (JVM)
The X
creates a software simulation of a CPU and
memory and handles all communication between
the Java program and the underlying operating
system and hardware.
