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

ObjectivesAt 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...

public static void main(String args[])
{
int a, b, add, sub, mul;
a=5;
b=3;
add=a+b;
sub=a-b;
mul=a*b;
System.out.println("add="+add);
