JRE 1255 introduces significant Java language features that enhance code readability, maintainability, and performance. These features include pattern matching, sealed classes, and records.

Pattern matching:
Pattern matching provides a more concise and expressive way to compare and extract data from objects. It allows developers to match objects against patterns and perform specific actions based on the match. This simplifies code and reduces the need for complex conditional statements.
Sealed classes:
Sealed classes restrict the subclasses that can be created from a base class. They ensure type safety and prevent the creation of unintended subclasses. This helps in maintaining the integrity of class hierarchies and improves code organization.
Records:
Records are lightweight and immutable data structures that represent simple data entities. They provide a concise syntax for defining data objects and enforce immutability, making them ideal for storing and manipulating small amounts of data.

These Java language features collectively enhance the developer experience and promote the creation of robust and maintainable Java applications. They simplify code, improve type safety, and provide better data handling capabilities. JRE 1255's support for these features makes it an essential update for Java developers looking to leverage the latest advancements in the Java language.

Cross-platform compatibility

JRE 1255's cross-platform compatibility is a cornerstone of its widespread adoption and versatility. It enables Java applications to run seamlessly on various operating systems, including Windows, macOS, Linux, and mobile platforms like Android and iOS.

This seamless execution is achieved through the Java Virtual Machine (JVM), a core component of JRE. The JVM translates Java bytecode into machine code specific to the underlying operating system. This allows Java applications to be developed once and deployed on multiple platforms without the need for platform-specific recompilation.

The importance of cross-platform compatibility cannot be overstated. It empowers developers to create applications that can reach a broader audience and run on diverse devices. For instance, a cross-platform Java application can be used to develop a mobile game that can be played on both Android and iOS devices, or a desktop application that can run on Windows, macOS, and Linux systems.
