An Introduction of Programming with JAVA
History and Origin of Java
All of us must do programming but when any one talk about Java, Then
all of them say - Java is an Awesome language as compare to other in most of
the feature. Why Java is popular and secure language and every programmer want
to program in java.
The seeds of Java were planted in 1990 by Sun Microsystems patriarch
and chief researcher, Bill Joy. That time Sun was competing with the
workstation market with other eminent company like Microsoft, IBM or other. But
Sun missed the most of the important thing of Pc evolution. Then Joy was
committed to the idea of accomplishing complex task with the simple software and
found a small work group Sun Aspen as here Java origin was started. The most
important and notable member of the Aspen was James Gosling who will be remembered
as the father of Java. He is also known for author of the first Linux Emacs
editor. Emacs was written in C on Unix Platform.
The First Person
team worked on developing software for information appliances, such as cellular
phones and personal digital assistants (PDAs). The goal was to enable the
transfer of information and real-time applications over cheap infrared and
packet-based networks. Memory and bandwidth limitations dictated small,
efficient code. Gosling and his teammates began programming in C++, but they
soon found themselves confounded by a language that was too complex, unwieldy,
and insecure for the task. They decided to start from scratch, and Gosling
began working on something he dubbed "C++ minus minus."
With the foundering of the Apple Newton, it became apparent that the
PDA's ship had not yet come in, so Sun shifted First Person's efforts to
interactive TV (ITV). The programming language of choice for ITV set-top boxes
was to be the near ancestor of Java, a language called Oak. Even with its
elegance and ability to provide safe interactivity, Oak could not salvage the
lost cause of ITV at that time. Customers didn't want it, and Sun soon
abandoned the concept.
At that time, Joy and Gosling got together to decide on a new strategy
for their innovative language. It was 1993, and the explosion of interest in
the Web presented a new opportunity. Oak was small, safe,
architecture-independent, and object-oriented. As it happens, these are also
some of the requirements for a universal, Internet-savvy programming language.
Sun quickly changed focus, and, with a little retooling, Oak became Java.
I will post the more feature of Java in Next blog post keep tuning

Customize the website(Facebook, Gmail, Yahoo etc) Color and interface
I am just writing this Post is about to customizing the interface of your browser (Chrome, firefox). If all of you file bored to using the default background and interface of your favorite website you can change and made it more comfortable as you want like following interface then follow the tutorial-
My Facbook Screen
My Youtue Interface
At first we have to go at following link and installed the theme named Stylish to our browser-
Click here for Chrome
Click here for Firefox
Note: I recommended Chrome because it is more comfortable in customization task
If link provide above doesn't work then go through extension website using browser and find the "STYLISH" theme in search box and install the extension.
Google Chrome :
Mozila Firefox:
Step 2:
Now Most of the configuration task is completed, It's time to add themes to particular website.
First of open the website and use the Stylish add-on to enable disable Manage or Find more theme online
1. Click on Stylish Icon and Enable, Disable, Delete the themes installed for facebook, gmail, youtube
2. We can select this option to find the more theme about the site with this link
Firefox:
1. We can find the STYLISH toolbar on firefox at the bottom of firefox form where more theme can be downloaded and managed
Thank You
Note:Stylish also provide facility to create own theme with the help of write new style option. All programmer can enjoy to work insite this interface.
Teachers of Today
I am upset because of my collage. Teachers of today think that he knows better than their student. I am not agree with him. Becuase, Teacher teachs the student one or two subjects but, A student read more subject at a time and some of them have better idea related to specific topic. I feel it more time but today I diappointed more....
