Programming

Lewis continues his series on how to avoid memory leaks in Java. This week he looks at the effect of string interning on memory.

Lewis provides some more examples of code that can lead to memory leaks, in particular how to use the static modifier.

Computer memory is a vital and scarce resource. So programmers must manage memory with care. Memory leaks can block file resources, reduce memory availability and degrade system performance. Lewis looks at some of the causes of memory leaks in Java.

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.
