Java is a high level programming language as well as computing platform which is simple, object oriented, distributed, multithreaded, dynamic, secure, fast and reliable in nature. It was firstly propounded by James Gosling who was at sun Microsystems and it was released in 1995 as a heart of Java platform. It is one of the best brands of the computer industries and the most widely used technology for web application from application software. Java, C and C++ are the major sources of structures of this programming language but it has easy object model and less low level facilities. It was previously called OAK and it was renamed as the Java programming language in 1995. There are many applications and web sites which cannot work without installing the Java and more are created every day. It is fast, secure and reliable. Java can be downloaded freely and it can be used everywhere such as; laptop to datacenters, cell phone to the internet, and game consoles to scientific super computers. There is an aspect of the Java software which is Java Virtual Machine (JVM) that is basically used in web interaction. It is constructed right in to the Java software download which helps to run Java applications.

What Java Technology actually does?

Java is the high level programming language and a powerful software platform which helps to develop the web pages to the web developers. Actually, Java Technology works as;

• Development tools: Development tools is that tools which provides all the required things which is necessary for compiling, running, monitoring, debugging and documenting the applications. The new developers use the tools Java compiler, Java launcher and java documentation.
• Application programming Interface (API): It provides the major functionality of the java programming language. It offers a broad range of relevant classes which are ready to use the user’s applications. It extents all the things from basic objects to security and networking, to database access and XML generation and so on.
• Deployment technologies: The standard technologies such as Java Plug in software, java web start software are provided by the JDK software for organizing our applications to the end users.
• User interface toolkits: Java 2D toolkits and swing facilitate to develop complicated user interfaces.
• Integrations libraries: The Java IDL API, (LNDI) Java Naming and Directory Interface API, JDBC API and Java RMI enable to access the database and remote objects manipulation.

Parts of Java Technology:

• Core Java: The core java training program is designed for programmers who are concerned to add the java programming languages in their list of knowledge and skills. This language is also useful for the student to enable them to develop better fundamentals and prepare them for Sun Certified Java Programmers (SCJP) certification.
• Advance Java: Advance Java is the Java training program which was developed by focusing to the Sun Certified Java technology programmers, who want to develop official applications that match to the Java EE platform standards. This program focuses to the java training programmers to specialize in the application of serve let technologies and Java server pages which is used to present dynamic web content and web services by using Java platform i.e. Enterprise Edition (Java EE technology). The students of Java can take the Sun Certified Web Component Developer (SCWCD) certification exams after finishing the advanced Java training program.
• Java EE: The Java EE (Enterprise Edition) is a broadly applicable platform which is used in Java programming language for server programming. The Java EE is absolutely different from the (Java SE) Java Standard Edition Platform in this sense that java EE inserts libraries which offer functionality to organize errors, dispersed multi-tier Java software which are running on the application servers.

Why Java technology is useful to the Software Developers?

Java the programming language has been experienced, modified, and comprehensive and it has been proven by the web developers’ community as an authentic source of web development. Java has become popular in the field of web development due to flexibility, efficiency and portability as a result more than 6.5 million developers are using this technology in the world. Java technology is popular due to the following qualities;

• Java facilitates to write software on one platform and run it to any other platform.
• Programs are developed to run within the web services and web browsers.
• Server-side applications are developed for online meetings, surveys, HTML forms processing, stores and many more.
• Applications or services are integrated to create highly adopted applications or services by using the Java language.
• An efficient and powerful applications can be written for remote processors, mobile phones, consumer products, low -costs and virtually any other tool with the digital heartbeat

Software development process with the help of Java:

• All the source code is written in blank text files ending with the Java Extension
• All the source files are compiled in to class files with the help of compiler
• Converting the languages in the machine level language with the help of Java virtual machine
• The particular application is run by Java launcher tool and it helps to run the program with the help of Java Virtual Machine.

File Installation procedures:

Basically there are three installation procedures such as- manual, offline or online installation procedures which are followed by the Java users to install the required files.

• Manual Installation Procedure: an IFTW (Install from the Web), executable program file is downloaded with the help of manual installation procedure. It obtain all the necessary files from the web when the users run this program but the users keep on waiting at the time of installation of the programs.
• Offline Installation Procedure: basically it is required to download the executable files which are listed at manual Java download. It contains all the required files for the final installations. There is no need to keep on waiting on the internet at the time of installation. The required file can be copied and installed on other computer which is not connected to the internet.
• Online Installation Procedure: the required files can be installed automatically with the help of Free Java Download page under online installation procedure.

From the above explanation, it is concluded that the java technology is a programming language which is applied to develop software by deriving the syntaxes from Java, C and C++. Java technology works as development tools, application programming Interface (API), deployment technologies, user interface toolkits, and integrations libraries. It is an important part of software development by applying different procedures such as – text filing, compiling, converting languages etc.
