Discovering the Hidden Features of Java

Java, a long-standing staple in the world of programming, continues to evolve, offering an array of powerful capabilities for developers. While many are familiar with its core constructs and commonly used libraries, several advanced features often go unnoticed. Let's delve into some of these hidden gems that can potentially supercharge your Java development efforts.

Parallel Streams

Java 8 introduced the Streams API, which many developers use for processing collections of objects. However, the hidden treasure here is the parallelStream(). Utilizing parallelStream(), you can leverage multicore processors for parallel computation, thus enhancing performance.

Sealed Classes

Introduced as a preview feature in Java 15 and officially in Java 17, sealed classes restrict which other classes or interfaces may extend or implement them. This can be particularly useful for maintaining controlled hierarchies.
