- The inclusion of scoped values augments safety, followed by the foreign function and memory API, enabling seamless native code interaction.
- Record patterns and pattern matching for switch statements and expressions introduce clarity to code organization.
- Last but not least, the vector API proposal aims to bolster parallelism in computation.
Java 20 encapsulates a diverse array of innovations, showcasing its commitment to adaptability and empowering developers to craft more efficient and expressive code.
Java 17, launched in September 2021, is a significant version known as a long-term support (LTS) release. It offers various improvements and features:
- Sealed Classes: This feature allows developers to control which classes can be subclasses of a given class, enhancing encapsulation and improving maintainability.
- Pattern Matching for Switch: Java 17 extends pattern matching to switch statements, streamlining code and making it more readable.
- Foreign Function & Memory API: This addition facilitates interaction with native code and memory, enhancing performance and integration with native libraries.
- Strong Encapsulation of JDK Internals: Java’s internal APIs are better encapsulated, boosting security and preventing unauthorized access.
- Deprecation of Applet API: The outdated Applet API is deprecated to promote modern web technologies.
- Sealed Types (Preview): A complement to sealed classes, sealed types control the types that can be used as type arguments, enhancing type safety.
These features improve security, performance, and developer productivity, making Java 17 a compelling choice for long-term projects.
Case study: ShopEasy’s usage of Java 17, Java 20, and Java 21 to enhance their e-commerce platform’s performance, security, and maintainability.
In December 2021, ShopEasy, an e-commerce platform, began to face difficulties maintaining and securing its online store due to unauthorized code changes.
ShopEasy then upgraded to Java 17 which provided sealed classes and stronger encapsulation. This led to resolving ShopEasy’s security issues and simplifying codebase management.
In mid-2023, ShopEasy’s high customer traffic strained its system, causing slow performance. Handling concurrent tasks and integrating new features became a bottleneck.
As a result, the platform switched to Java 20’s virtual threads and structured concurrency that enabled ShopEasy to handle more customers at once without slowing down.
As the online store expanded, handling increasing data volumes became a challenge. To process data efficiently and maintain high performance, ShopEasy is now planning to upgrade Java 21’s vector API and pattern matching.
This will help the platform manage things better behind the scenes and make their store smoother for customers.

The rise of Kotlin, a modern programming language developed by JetBrains, is poised to impact the future scope of Java. As Kotlin gains more mainstream adoption, especially on Android, Java developers may feel pressure to learn it. However, Kotlin is interoperable with Java and runs on the JVM, so Java skills will still be relevant.
Kotlin code can call Java code and vice versa. Libraries and frameworks written in Java are still usable from Kotlin. This means Java developers can leverage their existing knowledge and benefit from Kotlin’s modern language features.
On Android, Kotlin is now the preferred language for developing apps. However, the Android framework and SDK are still largely built on Java. For server-side development, Spring Boot – the popular Java framework – officially supports Kotlin. But again, much of Spring is written in Java, and Java skills translate well.
To make it straightforward, while Kotlin may chip away at future scope of Java’s popularity, especially for mobile development, Java itself isn’t going anywhere soon. Its widespread use, compatibility with Kotlin, and importance to enterprise software mean strong career opportunities will remain for Java developers. Kotlin is poised to impact Java, but not replace it.
If you want to become a professional developer, learning Java is a perfect place to start. Here’s why:
- Versatility: Java offers diverse applications, from streaming apps to web, mobile, big data, IoT, blockchain, and AI. It’s a versatile choice with real-world relevance.
- Future-Proof: Java’s role in FaaS, serverless apps, and Android OS ensures its place in the future of development.
- Progressive Updates: Java keeps up with the latest trends, updating every six months to stay current.
- Friendly Learning Curve: While not the easiest, Java’s value and future prospects make it worth learning, especially for a promising career path.
The demand and future scope for Java is high. Java developers are in high demand in the job market. Learning Java will open you up to many career opportunities as a software engineer or web developer.
According to Glassdoor, the average Java developer in the US earns anywhere between $96,000 to $99,000 per year. Whereas, for junior developers, the approximate salary is $80, 533 per year.
Experienced developers with 5-9 years of experience can make $103,000 per year, 31% higher. The job outlook is also quite positive. The US Bureau of Labor Statistics projects a 22% growth for software developers between now and 2026, much faster than average.
