The Principle of Least Surprise (POLS), also known as the Principle of Least Astonishment (POLA), is a design guideline for both software and user interfaces. It says that every component in a system should behave in a way that most users expect it to behave, and therefore not surprise or astonish them.

Lewis looks at how to schedule tasks to run regularly, using the ScheduledThreadPoolExecutor. This is the last part of our series on threads and multithreading in Java.

This is part 9 of the series on threads and multithreading in Java. Lewis looks at how to gracefully shut down the Executor objects, and how to schedule tasks to run regularly.

This is part 8 of the series on threads and multithreading in Java. Lewis looks at the TimeUnit enum and some of the other methods of the Future interface.

In part 7 of the series, Lewis looks at how to create Executor and ExecutorService objects. He also explains how to run Callable objects and access their return values using the Future interface.

In part 6 of the series on threads and multithreading in Java, Lewis looks at the difference between runnable and callable.

In part 5 of this series, Lewis looks at how to synchronize threads in Java. He explains why threads must be synchronized, and how Java objects are locked. Learn how to use the Java synchronized keyword and the various synchronized methods in Java.

We continue the series on threads and multithreading in Java. In this post, Lewis looks at how to terminate a thread gracefully, and how to interrupt threads.

This is part 3 of the series on threads and multithreading in Java. In this post Lewis looks at daemon threads and thread groups.
