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.
Another objective was to name the language & its is surprisingly to find a good name. Finally, inspiration struck one day during a trip to the local coffee shop” Gosling recalls. 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.
As a programmer we generally wants language to have pleasant syntax i.e. java eliminates many rarely used ,poorly handled & confusing features of C++.Some language have portability, garbage collection and many more features but they don’t necessarily have much of a library, forcing to roll back if we want fancy graphics ,networking & Database access.
Some of the Features that we describe here are extracted from a white paper, where java Developers explained theirs goals. Following are some of them.
Cleaned up version of C++ is in fact Java. Many Cumbersome features like pointers, structures, unions, header files and so on are removed from java language. This makes Java a simpler & power full programming language.
Another aspect of java simple is being small. one of the major goals of java is to enable the construction of Software which can run stand alone in small machines. The size of the basic interpreter and class support is about 40k bytes, adding the basic standard libraries and thread support (essentially a self-contained microkernel) adds an additional 175 k.
This was a great achievement at the time. As time passed on the library has grown up rapidly. This had prompted to come up with micro editions of java.
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.
The remote method invocation mechanism enables communication between distributed objects very easily. To test you can ask anyone who has tried to do Internet programming using another language will revel in how simple Java.
