New Java 21 Feature : A Guide to Virtual Threads in Java!
- Java has introduced Virtual Threads, a new feature for running multiple tasks concurrently in a simpler and more efficient way.
- Threads in Java are like helper workers that perform different tasks.
- Virtual Threads, part of Project Loom, are lightweight threads created by JVM, enabling the creation of thousands of threads without memory concerns.
- Virtual threads do not block OS threads, use less memory and CPU, and are suitable for I/O-heavy tasks.
- To create a virtual thread, you can use Thread.startVirtualThread(() -> { // Your logic });.
- Virtual threads offer advantages like clean and readable code, simplifying complex thread management, and handling numerous tasks effectively.
- They are ideal for applications handling many users or requests, especially I/O-heavy tasks.
- However, for CPU-intensive tasks, virtual threads may not provide significant benefits.
- Virtual threads eliminate the need for learning complex async or reactive programming and allow efficient handling of tasks.
- Overall, virtual threads are a significant improvement in Java, enabling the creation of clean and efficient code for concurrent processing.
