This Course covers java from very beginning i.e. if you are new to java don’t worry we will start java from basics in detail. This hand on training tutorials will help you to kick start your java learning skills and also will allow you to understand & start programming in java.
Let me introduce myself. I am Madhu Sudan Uligiaur, started programming 8 years ago as Java Developer in one of recognized CMM Level V Organization. The gap between learning centers & working Environment at organization level & also very few java training organizations provide Hands on & Quality Training, this urged me to start training .Let me hope that this tutorial will be helpful .

In 1991 James Gosling & team members (Mike Sheradin, Patrick Naughton & several others) meet to discuss about a Project (called Stealth) .
The goal of the project was to do research in the area of Computers in the consumers electronics Field.
According to Gosling “the goal was … to build a system that would let us do a large, distributed, heterogeneous network of consumer electronic devices all talking to each other.” With this goal in mind, the stealth group began work.
Members of this project (later Stealth project was named as Green Project) divided tasks & began to work on it. Mike Sheradin focused on Business Development; Patrick began to work on graphics system. James Gosling’s work was to indentify suitable programming language for the project. Soon after he was convinced that c++ was adequate for this project. His extensions and modifications to C++ (also know as C++ ++ –), were the first steps towards the development of an independent language that would fit the project objectives. He named the language “Oak” while staring at an oak tree outside his office window!
According to Gosling, the team discovered that Oak was name of the programming language predated to Sun’s Language and was copyrighted and for another programming language so they dismissed the name oak.
Finally, inspiration struck one day during a trip to the local coffee shop” & named language as ‘JAVA‘
Several others have speculated that the name Java came from several individuals involved in the project: James gosling, Arthur Van hoff, Andy bechtolsheim.
Java is simple object oriented programming language similar in to C, C++, COBOL, Fortrain and others.
Java is Simple & eliminates many unwanted features of C++ which are not used.
It has vast inbuilt library to make programming simple & Easy. Features of Java can be called as BUZZ Words.
Some of the Features that we describe here are extracted from a white paper are given below.
Cleaned up version of C++ is in fact Java. Many Cumbersome or problematic features like pointers, structures, unions, header files and so on are removed from java language. This makes Java a simpler & power full programming language.
At this point of time you may be or may not know object oriented concepts. Don’t worry by the end of this tutorial you will be learning most of them.
Java virtually can work on any Network & also any changes made in the network will not affected java functionality.
Java does not support multiple inheritance & pointers used in C++ which are root cause for Failures & hence we can say java is Robust.
The JVM verifies each class at run time to check the correctness of the program- normally checks unhealthy or malicious programs.Java does not Allow Reading or writing files without permission which makes Java secure.
Java is independent of the Operating System & Hardware used in the machine.
The Java compiler compiles the source code into bytecode,the bytecode in turn does not depend upon any machine architecture, but can be easily translated into a specific machine by a JVM for that machine.
Unlike C and C++, there are no “implementation-dependent” aspects used in Java.This makes programs portable among different platforms such as Windows, Mac, and Unix.
