Benefits of Java over Other Programming Languages

Java is a high level programming language and computing platform developed by Sun Microsystems in 1995. Since then, the language has been regularly updated with Java SE 8.0 version being the latest version, released in March 2014.

Based on the advantages of Java, it gained wide popularity and multiple configurations have been built to suit various types of platforms including Java SE for Macintosh, Windows and UNIX, Java ME for Mobile Applications and Java EE for Enterprise Applications.

With the growing importance of web based and mobile based applications, Java today is the foundation for most networked applications and is considered to be useful for scripting, web-based content, enterprise software, games and mobile applications.

Applications of Java

Every enterprise uses Java in one way or other. As per Oracle, more than 3 billion devices run applications designed on the development platform. Java is used to design the following applications:

  • Desktop GUI applications
  • Embedded systems
  • Web applications, including eCommerce applications, front and back office electronic trading systems, settlement and confirmation systems, data processing projects, and more
  • Web servers and application servers
  • Mobile applications including Android applications
  • Enterprise applications
  • Scientific applications
  • Middleware products

Advantages of Java

  • Java offers higher cross- functionality and portability as programs written in one platform can run across desktops, mobiles, embedded systems.
  • Java is free, simple, object-oriented, distributed, supports multithreading and offers multimedia and network support.
  • Java is a mature language, therefore more stable and predictable. The Java Class Library enables cross-platform development.
  • Being highly popular at enterprise, embedded and network level, Java has a large active user community and support available.
  • Unlike C and C++, Java programs are compiled independent of platform in bytecode language which allows the same program to run on any machine that has a JVM installed.
  • Java has powerful development tools like Eclipse SDK and NetBeans which have debugging capability and offer integrated development environment.
  • Increasing language diversity, evidenced by compatibility of Java with Scala, Groovy, JRuby, and Clojure.
  • Relatively seamless forward compatibility from one version to the next

What is Java Platform?

Java platform is a collection of programs that help to develop and run programs written in the Java programming language. Java platform includes an execution engine, a compiler, and a set of libraries. JAVA is platform-independent language. It is not specific to any processor or operating system.

To understand JAVA programming language, we need to understand some basic concept of how a computer program can run a command and execute the action.

What are Assembler and Compiler?

With the advancement in technology i/o devices were invented, you could directly type your program into the PC using a program called ASSEMBLER. It converts it into corresponding machine code (110001..) and feeds to your processor. So coming back to our example addition of (1+2), the assembler will convert this code into machine code and give the output.

That apart, you will also have to make calls to create Operating System provided functions to display the output of the code.

But alone assembler is not involved in this whole process; it also requires the compiler to compile the long code into a small chunk of codes. With advancement in software development languages, this entire assembly code could shrink into just one line print f 1+2 A with the help of software called COMPILER. It is used to convert your c language code into assembly code, and the assembler converts it into corresponding machine code, and this machine code will be transmitted to the processor. The most common processor used in PC or Computers are Intel processor.

That apart, you will also have to make calls to create Operating System provided functions to display the output of the code.

Though present-day compilers come bundled with assembler can directly convert your higher language code into machine code.

Now, suppose Windows operating system is running on this Intel processor, a combination of Operating System plus the processor is called the PLATFORM. The most common platform in the world is the Windows, and Intel called the Wintel Platform. The other popular platforms are AMD and Linux, Power PC, and Mac OS X.

Now, with a change in processor, the assembly instructions will also change. For example the

  • Add instruction in Intel may be called ADDITION for AMD
  • OR Math ADD for Power PC

And obviously, with a change in Operating System, the level and nature of O.S level calls will also change.

As a developer, I want my software program to work on all platforms available, to maximize my revenues. So I would have to buy separate compilers which convert my print f command into the native machine code.

But compilers come expensive, and there is a chance of compatibility issues. So buying and installing a separate compiler for different O.S and processor is not feasible. So, what can be an alternative solution? Enter Java language.

In conclusion, almost 20 years after its inception, Java continues to deliver considerable value to the world of software development. Java 8, in fact, offers new features such as a scalable and flexible platform for the Internet of Things, less boilerplate code, new date and time library and API, refreshed graphics toolkit, integration with JavaScript, and others.
