About Java Programming Language
Java is a feature-rich modern computer programming language. It is a general-purpose language that offers all the feature that is required to implement a new system. Java is dubbed as “write once, run anywhere” as it is not dependent on the computer architecture, thanks to the Java Virtual Machine (JVM). Java Bytecode is compiled and runs on JVM machine for portability purposes. James Gosling developed it at Sun Microsystem in 1995. From there, it has grown stronger each passing day. Mostly, it is used for developing enterprise level applications and client-server web application. It is also extremely popular among the developers with over 9 million developers using the programming languages. Java is also famous for teaching coding to beginners as it is often chosen as the language of choice for first-time learners. Learning Java is also very easy, thanks to hundreds and thousands of tutorials available online.
Java history is rich and vibrant. It all started with Patrick Naughton, James Gosling, and Mike Sheridan as they started working on a project in June 1991. The language is aimed to designed for interactive television. Initially, the language was named Oak because of the oak tree outside this office. With a name change of “Green,” it was finally named to Java. The final name is derived from Java coffee.
Java programming language is inspired by the C/C++ style according to Gosling. The aim was to create a programming language independent of the underlying machine architecture.
The first public release of Java happened in 1995 as Java 1.0. New versions were released with time. Java also became the open source on November 13, 2006. It was released under the GNU General Public License (GPL) terms. Java is a powerful programming language and is used almost everywhere, including small microchips to powerful supercomputers.
Tools are universal to any programming language you use. Java is no different. It has some tools that you must use to make the most out of Java programming language. Using the right tool will help you improve your productivity and workflow. So, what tools should you choose? Let’s go through some of the best Java tools!
- Gradle: A simple build tool for Java projects. It let’s you do publishing, testing, building, deployment and manage your project. It is a must have tool for Java programmers.
- Eclipse: Eclipse is a popular open-source IDE for Java and is used by hundreds and thousands of Java programmers
- IntelliJ: IntelliJ is yet another IDE for Java programming language. It is built by JetBrains and available in the community edition. You can also opt to get the commercial edition which comes with better features and support.
- YourKit: Yourkit is a simple Java profiler. It works by combining the powerful analysis and on-demand profiling. It can be used both in production and development and seems great for application server integration.
- Clover: Clover is a Code coverage developed by Atlassian. It runs inside your IDE and helps you do continuous integration. Also, it lets you do test optimization for better application performance.
- Mockito: Mockito is an open-source mock library that lets you successfully create mocks. You can do all the steps including verification, creation, and stubbing.
- Jetty: Are you looking for an embeddable, lightweight app server, Jetty is your answer!
- Hibernate: Hibernate implements the Java Persistence API and is an Object-relational mapper.
- VisualVM: JVM can be a complex thing to manage. With VisualVM, you can troubleshoot the problem and ensure maximum efficiency.
- JUnit: Unit testing is important and tools can help you do so. With JUnit, unit test framework, you can test your app and make progress in TDD environment.
- Jenkins: Jenkins is a must have tool for Java programmers. It is a continuous integration tool and can be customized with hundreds of available plugins.
- Guava: Guava is a utility library. The library contains hundreds of core libraries used by Google. The core libraries can only be used for Java-based projects. For example, it can be used in primitives support, common annotations, string processing, etc.
- FindBugs: Finding bugs is an important part of programming. With Fingbugs, you can find a bug in your code using the static code analyzer. It categories bugs into different level such as scary, troubling, scariest, or “of concern”. It can also be used in IDE as plugins or as a standalone program.
- Jackson: Jackson is a JSON parser. It is lightweight, ergonomic, and fast to use, compared to simple JSON.

- Kent Beck, creator of the Extreme Programming and Test Driven Development software development methodologies. Furthermore, he and Erich Gamma created JUnit, a simple testing framework, which turn into the de facto standard for testing Java-based Web applications. The combine of JUnit and Test Driven Development makes a big changed on the way of coding Java, which causes many Java developers are not willing to follow it.

- Craig Mcclanahan, creator of Struts, a popular open source MVC framework for building Java-based web applications, which is arguably that every Java developer know how to code Struts. With the huge success of Struts in early day, it’s widely implemented in every single of the old Java web application project.
- James Gosling, generally credited as the inventor of the Java programming language in 1994. He created the original design of Java and implemented its original compiler and virtual machine. For this achievement he was elected to the United States National Academy of Engineering. On April 2, 2010, he left Sun Microsystems which had recently been acquired by the Oracle Corporation. Regarding why he left, Gosling wrote on his blog that “Just about anything I could say that would be accurate and honest would do more harm than good.”
