Java, the ubiquitous programming language, continues to evolve with each iteration. Java 21, released in September 2023, brings a wave of exciting features that enhance performance, improve developer productivity, and pave the way for a more modern and expressive language. Let’s delve into the core aspects of Java 21 and explore how they can empower your development endeavors.

1- Virtual Threads: A Game Changer for Scalability

One of the most significant introductions in Java 21 is virtual threads. Traditional threads in Java can be resource-intensive, as each thread requires its own operating system resources. Virtual threads, however, are lightweight alternatives that leverage the existing threads within the Java Virtual Machine (JVM). This enables developers to create a larger pool of threads without incurring the overhead associated with native threads.

Virtual threads offer several advantages:

Improved Scalability: Applications can handle more concurrent requests efficiently, leading to better performance under heavy loads.

Reduced Memory Consumption: By eliminating the need for separate OS resources for each thread, virtual threads help conserve memory.
