JAVA

About Java

Java is a general purpose, high-level programming language developed by Sun Microsystems. It is an object-oriented programming language originally developed by Sun Microsystems and released in 1995. Java programs are platform independent. Java code that runs on one platform does not need to be recompiled to run on another platform. Java Virtual Machine(JVM) executes java code. It is not written in Java and hence cannot be platform independent and Java interpreter is actually a part of JVM.It was only used to design and program small computing devices but later adopted as one of the platform-independent programming languages. The most important feature of Java is its byte code that can be interpreted on any platform including Windows, Linux, etc. Like PHP and ASP, Java Server Pages based on a code with normal HTML tags, which helps in creating dynamic web pages.

Ecommerce

In simplest form ecommerce is the buying and selling of products and services by businesses or consumers over the World Wide Web. People use the term “ecommerce” or “online shopping” to describe the process of searching for and selecting products in online catalogue and then “checking out” using a credit card and encrypted payment processing. Internet sales are increasing rapidly as consumers take advantage of

• Lower prices offered by vendors operating with less margin than a bricks and mortar store.
• Greater convenience of having a product delivered rather than the cost of time and transport and parking of going to a store.
• Sourcing product more cheaply from overseas vendors.
• Great variety and inventory offered by online stores.
• Comparison engines that compare and recommend product.
• Auction sites, where they did for goods.

Java & its features

Java is a simple programming language and easy to understand because it does not contain complexities that exist in prior programming languages. In fact, simplicity was the design aim of Javasoft people, because it has to work on electronic devices where less memory/resources are available. Java contains the same syntax as C, and C++, so the programmers who are switching to Java will not face any problems in terms of syntax.
