Now let’s look at the current role it plays in today’s technology and some of the industries that use it, and what that means for you. With this new up-and-comer on the scene, Java applets slowly began to lose their hold on the interactive web. Finally, after many years, Oracle announced in 2016 that they planned to depreciate Java applets in their next release of Java .

  • Having Object-oriented features, Java code is organized into classes and follows the paradigm and OOP principles of inheritance, encapsulation, and interfaces.
  • All of these frameworks are written in the Java programming language.
  • It is still commonly used in the web development industry for database management and other uses.
  • Java was developed by a group of developers at Sun Microsystems in 1995 and is now owned by Oracle.

Java is compatible with all popular operating systems like Mac OS, Windows or even Linux. The requirement and utility of Java is not restricted to computers alone as cell phones and gaming consoles also utilize Java to function properly.

On November 13, 2006, Sun released much of its Java virtual machine as free and open-source software , under the terms of the GPL-2.0-only license. Java gave web developers the ability to build dynamic websites that reacted to user input, and its popularity took off from there.

With it, developers can “write once, run anywhere” , meaning that the compiled Java code will run on all Java-compatible platforms without the need for recompilation. In the software development world, choosing the right programming language for a project is vital to a developer’s success. Ensuring the language has all of the features to meet the project’s requirement is key. In this tutorial, we will look at two languages that have been around for decades and enjoy widespread use. In particular, we will delve into Java, an Object-oriented language, and Perl, a scripting language. Each has their own strengths, weaknesses, and applications, which we will be reviewing.

Java provides the environment to develop cloud-based applications. The cloud application widely used to share data between companies or to develop applications remotely. Java also wins points with strategic planners for its ability to adapt to new use cases. For example, Java is widely considered to be an ideal platform for the Internet of Things . The typical IoT application interconnects a large number of disparate devices, a task that is greatly simplified by the fact that billions of devices run Java.

Perl’s syntax, meanwhile, is very flexible, which can make it a bit harder to read and understand from a programming logic and structure standpoint. The language itself is pretty human-readable and even non-programmers can typically get the gist of what code itself means. Perl features a variety of shortcuts and implicit behaviors, however, that can further contribute to its lack of readability if you are not overly familiar with the language.
