Episode 7. Threads, Priorities, and Swing’s Golden Rule

In this episode we talk about Threads and Threading, the difference between Daemon and User Threads, and why changing priorities is not for the weak of heart. Also we cover Swing’s golden Threading rule (with the Event Dispatching Thread). If you ever typed new Thread(), or if you heard to be careful about Swing and Threading, this episode is for you!

 

Episode 6. Observing the Observers, a talk about patterns, observer and listeners!

In this week’s podcast we talk about Design Patterns (and the Grand Dads of the Software Patterns, the Gang-of-four), and dive into our first design pattern (of many), the Observer pattern. We discussed how to implemented (within Java), and went to describe its use in Java Swing, and why anonymous inner classes for Listeners doesn’t create memory leaks (most of the time anyways). In all a great introduction to a first pattern (see what they are all about!)

 

Episode 5. Producing and Consuming, ThreadPoolExecutor, and Latency vs Throughput

In this podcast we dive into the age-old producer and consumer problem, talked about the different aspects of it (what does it really solve?), and explain the difference between throughput vs latency. Lastly we discuss the ThreadPoolExecutor and how to fine tune it for your particular project needs!

 

Episode 4: List, Set, Maps, HashCode, Equals and ConcurrentMap! Everything to know about Collections!

In this episode we describe the most used collections in the Java framework, and how can they help you out. We also talk about maps (and the importance of immutable keys), and the equals/hashcode contract (why are these anyways? :). Finally we discuss how to safely access these collections/maps from different threads (and cover the check-then-act operations in maps). If you used a map, or ever got a ConcurrentModificationException, this episode is for you!
