To efficiently utilize the performance capabilities of modern multicore computers, software must be designed and developed accordingly. Multithread programming is thus becoming mainstream. Java is particularly well-suited for the upcoming paradigm shift due to its wide-ranging concurrency concepts. The authors provide a comprehensive introduction to concurrent programming with Java in this book. In addition to the basic concepts, the focus is on modern abstract synchronization and parallelization concepts, such as the Fork-Join framework and the parallel streams and CompletableFutures introduced in Java 8. The safe handling of threads is also addressed. Many concrete examples demonstrate practical applications.
