Mastering Java 17: An In-Depth Look

The latest long-term support (LTS) release, Java 17, emerges from the open-source Java Development Kit (JDK). Offering several enhancements over its predecessors, it provides developers with more powerful tools for writing multifaceted applications. This article seeks to provide a thorough understanding of Mastering Java 17, examining its features, advancements, and its significance in the programming universe.

Mastering Java 17: Discover What’s New

JEP 356: Advanced Pseudo-Random Number Generators (PRNGs)

The introduction of a new interface, java.util.random.RandomGenerator, in Java 17 provides a consistent API for all existing and new pseudo-random number generators (PRNGs). This gives developers the flexibility to select from an array of PRNG algorithms, ensuring enhanced robustness and adaptability.

JEP 391: macOS/AArch64 Port

Java 17 expands its support to macOS/AArch64 Port, facilitating developers to create and execute Java applications on Mac devices equipped with Apple Silicon.

JEP 398: Sunsetting the Applet API

Consistent with contemporary web standards, Java 17 announces the deprecation of the Applet API. This decision aligns with the industry’s shift from applets towards more secure and transportable web technologies.

Mastering Java 17: Advantages and Enhancements

Sealed Classes

The introduction of sealed classes and interfaces in Java 17 offers a more flexible access control mechanism. Sealed classes limit which other classes or interfaces may extend or implement them, improving encapsulation and readability.
