Java is a cluster of computer software that collectively runs a system. This system improves specific application software deploying them in a cross platform computing environment. Such platforms include embedded devices, mobile phones, enterprise servers and super computers.


Java applets are used on the internet to provide a better browsing experience compared to the basic HTML browsing interface. Java Runtime Environment (JRE) applications are equipped with libraries, Java Virtual Machines and other components for it to function properly. The main deployment technologies Java Runtime Environment (JRE) uses to run in popular browsers are Java Plug-in and Java Web Start to deploy stand- alone applications over a network.

A Java Runtime Environment is a Java platform that is comprised of Java libraries and the Java Virtual Machine. The Java platform begins with the Java compiler which converts Java source code into Java byte code for the Java Virtual Machine (JVM). The Java Virtual Machine program executes other programs that contain Java byte code instructions. A Just-in-time (JIT) compiler then converts intermediate byte code into native machine code in real time. This, together with an extensive set of libraries form the Java platform, is what is responsible for the running of applications that facilitate chatting and watching trailers on the internet.
Java byte code is an intermediate programming language compiled mainly from Java. Byte code remains the same no matter what hardware or operating system the program is running under. The heart of the Java platform is the concept of “virtual machine” because that language used is what is referred to as a “write once, run anywhere” programming language. The use of byte code permits programs to run on any platform that has a virtual machine available. Java byte code can also execute automated exception handling which basically provides debugging information for software errors.


Currently Qt is competing with Java commendably in the field of Desktop Applications. There are also many rewritten programs from Java to Qt. C# is also starting to show up on more platforms thanks to Mono, but not the same as the cross platform that Java provides. Objective-C used in Apple-specific development has impressive features but is equally challenged by Java in the mobile space thanks to Android. Python, Ruby are likewise good and productive languages but cannot compare to the JVM performance in terms of presentation and industry acceptance or range of libraries. Having a strong command over other programming languages, Java continues to show dominance as it has included online Certificate Revocation Checking, new JAR Manifest File Attributes, it has new properties for secure validation of XML and can also change to Runtime.exec.


Java is by far the best programming language there is. It is easy to learn, write, compile, debug and run. It is object oriented on an independent platform and with the ability to move easily from one system to another. The ability to run the same code on many different systems is crucial for the internet. Java is the programming language of choice because it is secure and reliable in checking problems and its multithreaded features will make it remain relevant for years to come.
