Java 16 introduced JEP 395: Records as an incubated feature, and with Java 17, this feature was standardized. Records provide a new way to model immutable data structures with less boilerplate code. They are a special type of class designed to hold data without needing the user to write code for typical methods such as …
JEP 394: Pattern Matching for instanceof is a significant feature introduced in Java 16 and enhanced in Java 17. The goal of this enhancement is to simplify and improve the use of instanceof for type-checking and casting. Traditionally, the instanceof operator required a two-step process: first, checking if an object is an instance of a …

Java 17 introduces an important update for macOS users with the new rendering pipeline based on Apple’s Metal framework. This change was made to replace the older OpenGL pipeline, which Apple has been deprecating over the years. The new pipeline improves performance and ensures better long-term compatibility with modern macOS systems. Why the Change? OpenGL …
One of the major goals of recent Java releases has been to make the platform more secure, reliable, and maintainable.A key step towards this goal is strong encapsulation of JDK internals, fully enforced in Java 17.In earlier Java versions, applications could access internal APIs (like sun.misc.Unsafe) that were never meant to be public.This created fragile …
Ahead-of-Time (AOT) and Just-in-Time (JIT) compilation are strategies for improving Java application performance.In earlier Java versions, experimental AOT and JIT compilers were introduced to explore new optimization techniques.However, starting from Java 17, these experimental features have been removed to simplify the JDK, reduce maintenance costs, and focus on proven, production-ready technologies. What Were the Experimental …
In earlier Java versions, Remote Method Invocation (RMI) allowed distributed communication by enabling objects to call methods across JVMs.An important extension to RMI was the RMI Activation system, introduced to activate remote objects on demand, reducing memory and resource usage. However, as technology evolved, Java 17 deprecated RMI Activation because it became outdated, complex, and …
Random number generation is a fundamental requirement in many software applications — from gaming, simulations, and modeling to cryptography and security.Before Java 17, developers mostly used java.util.Random or java.security.SecureRandom classes for random number generation. However, these traditional generators had limitations such as low randomness quality, limited algorithm choice, and lack of parallel stream support. To …
Concurrent collections are specialized data structures in programming that facilitate safe and efficient manipulation of shared data by multiple threads in a concurrent environment. Traditional collections, like lists, queues, or maps, often face issues like race conditions when accessed by multiple threads simultaneously. Concurrent collections address these issues by providing built-in thread-safe operations. Concurrent collections …
Java 17 enhances pattern matching for switch statements and expressions, building on features introduced in earlier versions. It introduces sealed classes and pattern matching to make switch constructs more expressive and concise. Below is a detailed explanation of pattern matching in switch as of Java 17, including examples. Important Features of Pattern Matching for switch …
Sealed classes are a feature introduced in JEP 409 (part of Java 15 as a preview, finalized in Java 17) to provide more control over class inheritance. They allow a class to restrict which classes or interfaces can extend or implement it, enabling more robust and maintainable hierarchies. Important Concepts of Sealed Classes …
