Uses Of Java

Why is Java so popular?

One of the main reasons Java is so popular is the independence of the platform. Programs can run on several different types of computers; As long as the computer has a Java Runtime Environment (JRE) installed, a Java program can be run.

Most types of computers will support a JRE, including those running on Windows, Macintosh computers, Unix or Linux computers, and large mainframe computers, as well as mobile phones.

Since it has been around for so long, some of the world's largest organizations are created using language. Many banks, retailers, insurance companies, utilities and manufacturers use Java.

Steve Zara, a programmer for more than 40 years, describes how there is no sign that Java usage is declining. Instead, it is an evolving language that almost uniquely combines stability with innovation.

Highlighting the longevity of the language, Zara states that code you may have written 15 years ago will run on the most up-to-date JVMs and gain the speed advantage of the latest profiling, native code translation, and memory management.


Java is fundamentally object-oriented. The code is so robust because Java objects do not contain references to data external to themselves.

Language is considered very simple; However, it comes with a library of classes that offer commonly used utility functions that most Java programs cannot work with.

The Java API, the class library, is as important a part of Java as the language itself. Actually, the real challenge of learning how to use Java is not learning the language, but learning the API.

The language consists of 50 keywords, but the Java API has thousands of classes with tens of thousands of methods that you can use in your programs.

Despite this, developers are not expected to learn the entire Java API, and most of them are only experienced and dominate a small part of it.

Is java worth learning?

Java remains a relevant programming language that shows no signs of losing popularity and, for that reason, is worth learning. Most developers choose it as their first programming language because it is reasonably easy to learn.

Because the language has an English-like syntax with a minimum of special characters, Java could be learned in a short period of time and used to build appropriate applications.

Java is part of a family of languages that are strongly influenced by C++ (as well as C's), so learning Java offers great benefits when learning these other two languages.

Swarnim Srivastava, a Java enthusiast, agrees that it is worth learning the language. Explains the critical areas in which it is used:


Creating Android apps

Although there are other ways to create Android apps, most apps are written in Java using the Google Android API. Although Android uses different JVMs and packaging methods, the code is still predominantly Java.

Java web applications

Many government, health, insurance, education and defense departments have their web applications integrated into Java. A significant example of this is Google Gmail.

Software tools

Many useful software and development tools are written and developed in Java, e.g. Eclipse, IntelliJ IDEA and NetBeans IDE.

Scientific applications

Today, Java is often the default for scientific applications, including natural language processing. The main reason for this is because it is safe, portable, easy to maintain and comes with better high-level concurrency tools than C++ or any other language.

Depending on your professional perspectives, Java can take you to different career paths. Whether you're interested in creating games, mobile apps, desktop apps, or web applications, Java is able to work in these environments.

Whether or not you use Java in your career or work function, you'll learn syntax, ideas, patterns, tools, styles, and idiosyncrasies that are also easily transferable to other programming languages.

Learning Java will give you the opportunity to see one language do something compared to another. Also, knowing what works for Java and other languages will make you an even better developer.


Why program in Java?

Java is easy to write and run; this is the fundamental strength of Java and why many developers program on it. When you type Java once, you can run it almost anywhere at any time.

Java can be used to create complete applications that can run on a single computer or distributed across servers and clients on a network.

As a result, you can use it to easily create mobile apps or run them on desktop applications that use different operating systems and servers, such as Linux or Windows.

Once a developer is familiar with installing JDK, configuring PATH, and understanding how CLASSPATH works, you can easily compile code.

There are many things you can do in Java and you can find libraries that do almost anything. With Java, there are better GUI (graphical user interface) systems than the default Abstract Window Toolkit (AWT) and Swing libraries.

In addition, you can connect to databases using Java Database Connectivity (JDBC).

For these reasons, the developer community is proving to be the strength of the language and its platform. A programming language would not survive if there was no community to support, help, and share their knowledge.

With tens of millions of developers using and working in the Java programming language, the community continues to grow and inspire.

The importance of Java

Since the language is as popular as it is, there are tons of resources to learn from. Fortunately, many of these resources are available online and can act as your partner in the learning process. Free and paid learning resources are available, depending on your skill level.

Technology is advancing at an incredible pace, which means there are many job opportunities nearby, and developers who have a strong knowledge of Java are in high demand.

With an existing foundation, the Java programming language continues to create many jobs in the technology industry.

OpenJDK is an open source and free implementation of the Java programming language. Because it is an open source programming language, it is platform-independent in all OS environments.


Java is a complete universal programming language. Because of its robustness and scalability, Java is found in mobile, desktop, and large-scale industrial servers and applications.

Recently, Java has gained credibility in the area of Internet of Things (IoT) and cloud development.

Globally, there are about 10 million Java developers, and this community continues to grow daily. Like other open source technologies, Java encourages the values of giving back to the public.

Online forums, such as StackOverflow, are made up of expert Java developers who are ready to help beginners.

Java is more commonly used in your daily life than you think. It is used on popular websites that you can use frequently, such as Google, YouTube, LinkedIn, Amazon and eBay. In addition, Java has a robust development roadmap with continuous progress in security and performance.

While Java doesn't adapt to all needs, it remains a popular programming language that is widely used and benefits many people and businesses.

Even after 22 years of existence, Java continues to evolve.
