While Java Threads explains the low-level details of using the Threads API, Concurrent Programming in Java, by Doug Lea, explores proper design of multithreaded programs.

To unlock the power of virtual threads in Java, developers must understand how they work versus traditional threads and how to avoid the problem of pinning.

Java historically has dealt with this problem partly through a powerful concurrency API and thread pooling. Now Java developers are abuzz about virtual threads, a feature introduced in Java 21. Java ...

JDK 21's virtual threads are a major leap forward for Java's concurrency model. Previously, Java relied on OS threads, which were resource-heavy, limiting how many threads could run concurrently.

Unfortunately, Java applications taking advantage of multiple threads can at times run into the dreaded deadlock condition. Fortunately, the Java Platform makes deadlock detection relatively easy.
