Java By Comparison

Use High-Level Concurrency Abstractions

Sometimes (most of the time, actually), you just need to make your program multithreaded. For example, you might have to handle multiple users at the same time in a web application. Or maybe you’ve got a desktop or Android application that interacts with the user and the screen in a UI thread and executes compute-intense tasks in background threads.

In those cases, you’ll typically let your threads communicate via shared memory: one thread writes a variable that another one reads, and vice versa. Java has supported such a built-in threading model and synchronization primitives since its inception. That’s been one of its major advantages in comparison to other high-level languages at the time.

These primitives ...
