by using unique features. Statement of "Hire java developers" can be seen nowadays mostly on every web development company website. Many of the outsourcing companies
prefer java developers for the website development and other web development tools for them because of the recent boom in the software market. Java developers are
producing not only websites but many other products can be seen in the market such as java equipped mobile phones, video games developed by using java, etc. At present
times, in order to have maximum & optimum utilization of java technology most of the companies are hiring java developers for web development projects. For the best
use of java technology features, professional java programmers are the best option and there is numerous web development companies providing java developers at
affordable prices. Java developers are rendering customized and flexible services in the field of web development according to specific needs of the clients all over
the world. By hiring java developers, companies can save their 60 % cost of production as compare to other developing sources like in-house development.
Hiring java developers are cost effective and more productive as they work dedicatedly only for the clients with professional expertise. Java technology is prevailing
for the last many years in the web development field and continuously providing its services, that's why java developers have worked a lot and this java development
technology is still providing numerous opportunities to them for producing web development tools. Java developers have gained fame in the web world because of amazing
technological features such as: Java developers can save precious money & time by creating modules once and can use again & again Java developers are popular because
java is object-oriented language, java use to provide great security to applications, java holds its own interpreter and compiler, java developers can do integration
with other systems easily, Java is very popular among developers because of following reasons.
• Presence on client side and server side both
• Java applications
can run on any platform with help of (JVM Java virtual machine) on client computer
• Java is platform independent
• Large number of libraries Hire concept of java developers is creating wonders in the web development, it has become popular by the professional use of java
technology, which is amazingly producing productive results for the users and developers are enjoying exciting carriers as well.
Importance of java
Java is an object-oriented programming language developed by Sun Microsoft.It is one of the development programming language. Java was chosen as the programming
language for network computers. It can be trianed by good Java Training center.Java has distributed, secure, architecture, robust, multi threaded and dynamic language.
The program can be written once, and run anywhere". One of the most significant advantages of Java is that, it has the ability to move easily from one computer to
another. It also has the ability to run the same program on many different operating systems.
Java Training applications are designed to be compiled and then interpreted at runtime, unlike the conventional programming languages, which can either compile source
code to native code or interpret the source code. The language itself has borrowed the syntax from C and C++. Java considers security as a part of its design. The Java

language, its compiler, interpreter, and runtime environment are all developed with security. Writing network programs in Java is similar to sending and receiving data
to and from a file.
The Java Training programming language was developed and re-designed for use on the Internet. In the internet domain, Java's popularity has increased tremendously,
especially on the server side of the Internet. Nowadays, there are a large number of Java experts who strive for the enhancement and improvement of Java development.
For beginners who are interested in learning Java, the numerous Java tutorials or Java Training available online are good to start with. Java tutorials or Java
Training and Java tips are the best resources for learning and improvising in Java.
Java Training Development experts are trying to enhance their programming skills for writing secure Java applications. In order to write a secure code in Java you need
to be aware of various things such as data handling techniques, user authentication rules, access controls etc. JavaScript is a scripting language which shares a
similar name and has the same syntax, but is in no way related to the core Java language..

Fresherlab is a young organization, based at India's IT hub, Bangalore.
It's a dynamic and competitive world with full of ups and downs in IT sector and therefore; the fresh engineers require just more than theoretical knowledge to get
themselves ready for the industry. Academic institutions across the world provide the basic and conceptual fundamentals covering multiple areas in computer science.
With increasing number of graduating engineers, but with constant number of companies, it becomes difficult for fresh engineers to compete with their unpolished skills
because they need more effective and specialized quality training.
Java is basically a programming language,which was originally developed by James Gosling (best known as the father of the Java programming language
) at Sun microsystems which is now a subsidiary of Oracle Corporation. It was first released by Sun in 1995. In short, it is the underlying technology that powers
state-of-the-art programs including utilities, games, and business applications. Java runs on more than 850 million personal computers worldwide, and on billions of
devices worldwide, including mobile and TV devices.
Why do people need JAVA?
There are lots of applications and websites that won't work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From
laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
Characteristics of JAVA
* The programs you create are portable in a network
* The code is robust, here meaning that, unlike programs written in C++ and perhaps some other languages, the Java objects can contain no references to data
external to themselves or other known objects.
* Java is object-oriented, which means that, among other characteristics, an object can take advantage of being part of a class of objects and inherit code that is
common to the class.
* In addition to being executed at the client rather than the server, a Java applet has other characteristics designed to make it run fast.
* Relative to C++, Java is easier to learn. (However, it is not a language you'll pick up in an evening!)
Difference between JAVA and JAVASCRIPT
JavaScript should not be confused with Java. JavaScript, which originated at Netscape, is interpreted at a higher level and is easier to learn than Java, but lacks
some of the portability of Java and the speed of bytecode. Because Java applets will run on almost any operating system without requiring recompilation and because
Java has no operating system-unique extensions or variations, Java is generally regarded as the most strategic language in which to develop applications for the Web.
(However, JavaScript can be useful for very small applications that run on the Web client or server.)
Editions
Sun has defined and supports four editions of Java targeting different application environments and segmented many of its APIs so that they belong to one of the
platforms. The platforms are:
* Java Card for smartcards.
* Java Platform, Micro Edition (Java ME) — targeting environments with limited resources.
* Java Platform, Standard Edition (Java SE) — targeting workstation environments.
* Java Platform, Enterprise Edition
(Java EE) — targeting large distributed enterprise or Internet environments.
