What is Java?

Java is a programming language and platform that Sun Microsystems released in 1995. It’s a long-standing language that offers specialized frameworks for developing software. It’s also compatible with a wide range of devices. Java code is turned into bytecode by the Java Virtual Machine (JVM), which runs on more than thirteen billion devices.

Java is one of the most popular languages in the world. Leading companies choose Java because of its ease of use, scalability, and reliability.
But Java is more than just a language. It comes with an extensive ecosystem, including the Java Runtime Environment, Java Development Kit, and Integrated Developer Environments. In addition, a large selection of open-source tools and technologies streamline the application building process.

Many Fortune 500 businesses, like Google, Uber, Twitter, and Amazon, use Java in their high-level applications.
Whatever application you want to build, Java is flexible and suitable for multiple uses. It’s an excellent choice for companies that want to develop scalable applications with industry-leading performance.

Thinking about using Java?

Java is a popular and reliable language

that meets the demands of even the most complex applications. From mobile applications to games to the internet of things, Java provides a highly adaptable ecosystem. So if you’re looking for a reliable language to build the foundations of your application, Java is well worth considering.

What Are the Benefits of Java?

Java has a range of advantages compared to other programming languages. From a business perspective, Java can reduce costs, scale with your development aims, and support high-performance applications.

Here’s an overview of the main benefits of Java:


Easy to Learn

Java is an ecosystem with simplicity at its core. It was designed as a high-level language that improves the unnecessary complexity and large memory requirements of C and C++.
Java offers significant amounts of reusable code as classes in libraries. In addition, it’s widely regarded as being easy to write in. This makes it accessible to developers of all levels of experience. And the stats back up this statement: more than 10 million developers worldwide are currently coding in Java.



Object-oriented programming (OOP) is more secure than procedural programming because apps built using OOP methodologies conceal data.
OOP also allows developers to champion important development features such as abstraction, encapsulation, inheritance, and polymorphism.


Platform independent

Java’s “Write Once Run Anywhere” philosophy means that apps built in Java can run on any platform with the Java Virtual Machine (JVM).



Java is a cost-effective choice for coders and helps to speed up the development process through open-source features and tooling. What’s more, Java’s high level of performance means that fewer machines are required to run applications.


Memory management

Good memory allocation is essential for the smooth running of devices and applications. When memory is running low, Java’s garbage collector automatically identifies unused items suitable for deletion.


Tools and Features

Java is a mature language with a large community. From libraries to tooling, developers have access to a wide range of open source development aids. Tools support developers by offering API features, error identification, code refactoring and formatting, and more.



Java supports distributed programming, which spreads processes over multiple nodes, thus increasing reliability and reducing latency.



Java’s Security Manager provides a sandbox for developers to test flaws within their applications. This is a must-have feature for test-driven development. In addition, Java provides packages specifically tailored to ensure security, along with built-in verifiers that check for malicious code.



Java runs multiple threads simultaneously. This saves memory and speeds up operations by running multiple processes concurrently. In addition, these threads work independently of each other, making the application in question run faster.

Who Is Using Java?

A wide assortment of brands, including many household names, use Java to run their websites and applications.
Here are four of the biggest enterprises currently leveraging Java:


Twitter uses Java to ensure reliability along with excellent performance and encapsulation.

Twitter initially developed its application using Ruby on Rails. However, it switched to Java because of the language’s ability to handle multiple events concurrently.

Twitter’s developers found that the JVM efficiently manages the constant API traffic on the platform, reducing the number of required machines while improving overall performance for users.

In addition, the JVM enabled developers at Twitter to identify errors more efficiently. The open-source community at OpenJDK was another significant draw.

Netflix’s developers believe innovation, rapid decision-making, and strong applications are the secret to staying competitive. So Netflix picked Java as part of their stack to keep up with the application’s constant growth.

Netflix built many of its services using Java and the JVM because of its scalability and reliability. Netflix’s applications run thousands of Java processes simultaneously without any impact on performance. 

A large number of open-source tools and frameworks used by Netflix, such as Spring Boot, are also Java-based. These tools streamline the development process by providing features that help with monitoring, testing, upgrading of applications, and more. 

eBay used Java to build the core of its tech stack because it’s a proven, stable language that could handle large amounts of traffic. 

eBay’s workflow is centered around Java and the JVM. eBay developers use Java SDK classes that enable Java applications to interact with APIs as if they were integrated. They found that the Java SDK reduced the complexity of setting up APIs and facilitated quick and efficient application development. 

Uber leverages Java to achieve the high-performance levels necessary for its complex application.

Uber’s sophisticated application can’t afford downtime. After creating its ecosystem primarily with Node.js and Python, Uber began using Java as the basis for new functionalities. Uber developers found Java to be optimal for integrating different tools and technologies.
