Here are some of the reasons why Java remains the most popular programming language for everything from mobile development to business and server-side apps that support the middle tier.

A new Java release with long-term support is on the way. Let’s have a look at some of the reasons why Java is still the greatest programming language for modern software development as it approaches its 25th birthday.

1. Quick to Learn

Every programming language has a real challenge, but Java and C, C++, and JavaScript have a lot in common. Anyone who has worked with any of those languages will be able to easily pick up Java syntax.

Java’s code structure is also governed by a set of highly strict and predictable constraints. This is in sharp contrast to other untyped scripting languages, where it appears that anything goes. When learning a new programming language, having a clear set of rules that are constantly enforced makes it easier to learn.

Additionally, when things don’t make sense, programmers new to Java can turn to YouTube videos, websites like StackOverflow, and online communities like CodeRanch for answers to a variety of concerns.

2. Java in API

The Java API has a lot of features. Over 200 built-in packages in the standard JDK include Java APIs for everything from parsing XML to converting across time zones. Developers that use the Jakarta EE APIs have access to an even larger set of APIs, allowing them to build complex middle-tier apps and cloud-native microservices.

However, the Java API ecosystem is much larger than those sanctioned by Oracle or provided by Jakarta.

The JBoss Hibernate project is for data persistence. The whole range of Spring Boot APIs is available for cloud-native microservices development in Java. Of course, there is a slew of open-source Apache API projects that cover anything from aggregating error messages with log4j to tackling complex problems with HashMaps and fail-safe Iterators via the Apache Commons Collections API.

The extensive variety of Java APIs available to developers aids in the creation of robust, error-free software.

3. Java ToolBox System

Software development tools created in Java — by Java developers — abound in the application development environment, all aimed to make the creation, deployment, and even decommissioning of Java applications easier and faster. A few examples of tools written in Java include: 

  • Gradle: an incredibly powerful, open source build tool
  • Maven: an open source tool designed to solve dependency management problems
  • Jenkins: a Java-based continuous integration and delivery tool

This is by no means a complete list of the Java ecosystem’s tools. Application servers like Tomcat, as well as Red Hat’s popular Kubernetes-native Java stack named Quarkus, are examples of Java-based tools and technologies.

Few other programming languages have the same amount of tools support as Java, allowing it to maintain its position as the finest programming language.

4. Fine Class Android Support

Android is the most popular mobile phone operating system in the world, and Java is the de-facto programming language for Android app development.

While Android’s version of Java isn’t identical to the JDK’s, Google did copy approximately 11,500 lines of code from the Java Standard Edition when developing their Java clone. As a result, Android developers may expect to see a version of Java that is quite close to the original.

You’ll take up Android development quickly if you know how to build Java code for desktop or server-side applications. After a small learning curve, you’ll be delightfully abstracted away from the low-level incompatibilities between the JVM and the Dalvik Android Runtime. When developers learn Java, the entire Android ecosystem will be at their disposal.

5. Great Evolutionary work in Java

Java advances at a leisurely pace, but it does so. With almost 25 years of evolution under its belt, Java has a long list of achievements to boast about.

Java continues to implement substantial changes that the community needs, from the robust modularity framework given as part of Project Jigsaw to the recently added capabilities of functional programming in Java with lambda functions.

Non-LTS releases provide incremental features like the new Record data type and garbage collectors for better memory management, demonstrating that the JDK is also continually growing.

Backward compatibility is just as crucial as adding new capabilities in enterprise software development. For the language’s stewards, this has always been a key priority. Rarely does a major update or feature addition cause problems with code built for previous versions.
