Latest Technology in Java

Java is a constantly evolving programming language, and there are always new technologies and features being introduced. Java 17 is the latest version of Java, released in September 2021. It includes several new features and improvements, including:


Records are a new feature in Java that provide a concise way to declare classes that are primarily used to store data. They are designed to be immutable and
provide a more compact syntax for defining data classes. Records can be used to reduce boilerplate code and improve readability in code that deals with data objects.

Enhanced pattern matching

This feature allows developers to use pattern matching with instance of, allowing for more concise and readable code.

Sealed classes

Sealed classes provide a way to restrict the inheritance hierarchy of a class, allowing for more control over the use of classes in a program.

Enhanced switch statements

The new switch statement syntax allows for more concise and expressive code.

Project Loom

Project Loom is an experimental feature in Java that aims to improve the performance and scalability of Java applications by introducing lightweight threads, also known as fibers. Fibers are similar to threads, but they are much lighter weight and can be created and destroyed much more quickly. This makes them well-suited for use in high-concurrency applications, such as web servers and microservices.

JEP 395

JEP 395 is a new feature in Java that provides a way to launch single-file Java programs directly from the command line without needing to compile them first. This makes it easier to write and distribute small Java applications, and reduces the overhead of managing build and distribution processes.

Reactive Streams

Reactive Streams is a technology that provides a standard for asynchronous stream processing in Java. It allows developers to build scalable, nonblocking applications that can handle large amounts of data. Reactive Streams is especially well-suited for use in applications that deal with real-time data streams, such as financial trading platforms and social media feeds


GraalVM is a high-performance virtual machine for running Java applications. It provides improved performance, lower memory usage, and the ability to run
multiple programming languages on the same platform.
GraalVM is particularly useful for building high-performance applications, such as machine learning models and data analytics platforms.

I hope this explanation helps! Let me know if you have any further questions.
