Why Java is So Popular?

One of the essential reasons for Java’s popularity is the cross-platform compatible and built-in security. Java program can run on any machine with a Java Runtime Environment (JRE) installed. Programs operate on various computers. Java is used by many banks, manufacturers, insurance organizations, utilities, and retailers. It is the reason that major industries ruled by Java.

In this section, we will discuss what makes Java so popular and what are the major industries that uses Java programming language.

Java Programming Language

Java is an object-oriented programming language. The object contains no references to data outside of themselves. The language is thought to be fairly simple, including a library of classes. The class library or Java APIs are a part of Java as the language itself. Although the language only has 50 keywords, the Java API contains thousands of classes and more than tens of thousands of methods that we can use in Java applications.

Despite this, developers are not expected to understand the entire Java API, and the bulk of them are merely knowledgeable and fluent in a subset of it.

Features that Makes Java Popular

The following features make the Java programming language special and popular.

  • Simple to use
  • Built-in Security
  • Open Source

Java uses cases have now full-fledged to include the Internet of Things (IoT), Data Science, and Machine Learning applications. It is the reason developers and programmers prefer Java programming language to build applications. It includes high-level concurrency tools and packages also take care of security. The Java classes and related tools create highly scalable solutions for the enterprise.

Open Source

To begin, Java is a popular programming language that provides a wide range of app creation capabilities. It is open-source, which implies that it is free to use. Any developer with a working knowledge of Java can use this free platform to create apps.

The Java Development Kit is likewise free to use for all levels of users, from beginners to experts. We utilize two JDK versions: Oracle JDK and the most recent OpenJDK.

Collection of Rich API

Although Java has 52 keywords, its Application Programming Interface (API) is both vast and rich. The Java API has methods to accomplish all types of tasks, such as networking, connecting to databases, processing XML, handling input-output, etc.

The open-source libraries such as Apache POI, Google Guava, Apache Commons, Apache Xerxes, OpenCV, Gson, can be easily integrated with Java.

Strong Community Support

The main reason for Java’s popularity is its active and supportive community. It claims to be the second-largest Stack Overflow community. So, if we ever get trapped in programming, other programmers or the Java community can help assist us and solve a problem.
