Java link

Java is great programming language for the development of enterprise grade applications. This programming Language is evolved from a language named Oak. Oak was developed in the early nineties at Sun Micro-systems as a platform-independent language aimed at allowing entertainment appliances such as video game consoles and VCRs to communicate . Oak was first slated to appear in television set-top boxes designed to provide video-on-demand services. Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web.

Java is an object-oriented language, and this is very similar to C++. Java Programming Language is simplified to eliminate language features that cause common programming errors. Java source code files are compiled into a format called bytecode, which can then be executed by a Java interpreter

Objectives

At the end of the lesson, the student should be able to:
● Describe the features of Java technology such as the Java virtual machine (JVM), garbage collection (GC) and code security
● Describe the different phases of a Java program



Java Background: History
● Java
– was created in 1991
– by James Gosling et al. of Sun Microsystems.
– Initially called Oak, in honor of the tree outside Gosling's window, its name was changed to Java because there was already a language called Oak.

Java Technology:
Programming Language
● As a programming language, Java can create all kinds of applications that you could create using any conventional programming language



Java Technology:
A Development Environment
● As a development environment, Java technology provides
you with a large suite of tools:
– A compiler (javac)
– An interpreter (java)
– A documentation generator (javadoc)
– A class file packaging tool
and so on...
