What is Java and why do IT Outsourcing Teams love it?
IT outsourcing teams have been using Java to program since the dawn of the millennium. Very few people know the beginnings of Java. In this article, we will explore the strengths and weaknesses of Java as continues to be a force in the industry.
In this article, we will explore the strengths and weaknesses of Java as continues to be a force in the industry.
What is Java?
Java is computer software that was created by James Gosling at Sun Microsystems in 1995. The core libraries and compilers were released under a proprietary license. It was later changed to GNU General Public License under compliance obligations of the Java Community Process.
Java has standard APIs, APIs that are open source, tools and enterprise solutions, big or small, trust the programming language.
It is used for
- Desktop Applications
- Web Applications
- Mobile Applications
- Web and Application servers
- Games etc.
Java’s latest version is Java 13, released in September 2019. Java has three editions
- SE – Standard Edition – for standalone and desktop variant
- EE – Enterprise Edition – for executing and developing components that run embedded in Java server
ME – Micro Edition – development for mobile and embedded devices
History of Java
Java project, initially named Oak, was kicked off in 1991 by James Gosling and his two other colleagues. It was named after Java Coffee, which came from Java, an island of Indonesia.
Java was structured on C/C++ for user convenience. The standard package was released in 1996 and Java Applets were integrated into web browsers and became popular. Java was an instant hit and the tech community lauded its configurable and enhanced security functionalities.
Java Community Process released versions 1.0 and 2.0 with enhanced security and bug fixes. Java 2.0 had several editions as mentioned earlier.
Java’s parent company Sun Microsystems was acquired in 2009-10 by Oracle.
Why use Java?
Java supports multiple OS
Owners can track their application progress and manage the SDLC better with effective communication and objective tracking.
Java supports multiple operating systems such as Mac, Windows, Linux, etc utilizing its neutral architecture to make desktop applications.
Java is blazing fast
It is believed that the initial versions of Java were slow.Java’s motto of “Write Once, Run Anywhere” was hard to achieve. Java’s virtual machine had to make compromises on its speed.
Java is the Most Popular Software Language
According to the TIOBE Index, Java is the most popular language for developers to learn.It is taught as a standard in countless universities due to its scalability in web and mobile app development.
The Java job market is always hot with unending possibilities. Investing your time in learning Java as your first language will surely be a better choice in the long run.
Java is Easy to learn and Master
Learning a language is an arduous and time-consuming process. This process is made easier if there is a low barrier for learning and Java provides that.
Java is an object-oriented as well as an imperative language that makes it easy for new learners. There are countless tutorials and forums online that help you with the process of learning Java. Object-oriented languages are easy to reuse and boost project deliverables.
If you are skilled in object-oriented programming, Java is easy to fall back upon with its rich API library and easy documentation.
Java is Free to learn
IT staff outsourcing companies are in the hunt for Java developers for their native development requirements.
Oracle has two versions of the Java SDK (Software Development Kit)
- Oracle JDK
- Oracle OpenJDK
Java’s syntax resembles C# and C++ which makes it easy for developers to change platforms and adds to the popularity of the language
Java has a humungous developer community
Java’s popularity and open source software has amassed a large community of developers and hobbyists.
The open-source libraries are ideal for people that want their issues resolved. The issues can be resolved by the community as well with forums dedicated to problem-solving. The community has developed excellent tools to complement Java such as IDEs ( Android Studio, IntelliJ IDEA,…), Application Servers ( TomEE, WildFly, Tomcat,…) and Dependency Managers ( Maven, Gradle, Ant,…)
Java is really secure
Java is a solid & secure language as it utilizes another machine to run your program. Your program passes on a Virtual Machine called JVM. This Virtual Machine uncovers many APIs for low-level machine customization you can make, but other than that you cannot tinker with machine commands. This complements the security aspect of the application.
Who should use Java?
Java is a complete language with multiple extensions into different domains with JVM and other resources. It should be utilized by
- Academics and Learners
- Inventors and Enthusiasts
- Professionals and Executives
- Team Managers
How Java Works
Java is run by a two-step compilation process. Java code is broken down into bytecode by the Java Computer. The bytecode is run by the JVM. Modern JVMs use a technique called dynamic translation to translate bytecode into native code machine can understand. These bytecodes generally have a .class extension.
Your code is machine-dependent and not operating system dependent, that is why Java is a cross-platform language and this philosophy is behind the working of cross-platform architecture.
This image explains the effect visually
Java is a statically compiled object-oriented language with a meteoric rise in the 90s. It has some tough competition with the likes of dynamic languages like Python.
This doesn’t diminish the value that Java brings and a developer needs to have an authoritative command on both compiling formats to broaden their expertise.
Java is questioned by the experts whether it can reliably cater to the needs of cloud and IoT. These questions are not validated by the critics as they want Oracle to take up a proactive role in its updates.
Java is a mature and reliable language and has stood the test of time. It has integrated into businesses over time and is not going anywhere soon.
