Baeldung Weekly Review 44
At the very beginning of 2014 I decided to start to track my reading habits and share the best stuff here, on Baeldung.
Curating my reading has made it more purposeful and diverse – and I’m hopefully providing value to you as well by allowing the best content of the week to raise to the top.
Here we go…
1. Java
===== >> Optional in Java SE 8
An useful guide to using the new Optional class the way it was meant to when it was introduced into the language. Like everything else, there’s a good way to use it, and then there’s all the other ways.
>> Better nulls in Java 10?
JDK 10 is still a long ways away – so now is the time for thought experiments. This is one of those – useful in the fact that it makes it clear that the semantics of null in Java can definitely be improved and should be.
>> 10 Things You Didn’t Know About Java
Cool list of corner cases and surprises in Java – an interesting read even if you’ve been doing Java for years.
>> On Java Generics and Erasure
An quick educational foray into how type erasure works in Java.
>> Beyond Thread Pools: Java Concurrency is Not as Bad as You Think
A very high level plotting of the Java Concurrency ecosystem – some of the available solutions and paradigms to get you started and knowing your options.
>> Hibernate collections optimistic locking
Another deep dive into Hibernate – this time showing how important the modeling of parent-child associations is for the way you’re able to concurrently and reliably access data.
And a few other Releases and Announcements that I’m excited about or are just noteworthy in the broader Java ecosystem:
2. Spring
ELK is a beautiful thing. I’ve been using it for a while now and it rocks.
>> Spring Caching abstraction and Google Guava Cache
It makes a lot of sense to use the Guava Cache to power the caching in a Spring app. This is how.
>> A quality @Qualifier
I’ve mainly used @Qualifier as an interview question, but from time to time it can turn a tricky situation into an elegant solution. And, as Josh points out – it’s been doing it for years.
>> Spring from the Trenches: Resetting Auto Increment Columns Before Each Test Method
An interesting deep-dive into working with a large suite of integration tests – how to make sure your results are correct and reproducible, and that your tests are idempotent.
Finally – a few cool Releases and Webinars from Spring:
3. Technical and Musings
“A method should do one thing”. It took a long time until I really internalized this fact and started actively looking for it in my own design.
And so I read this piece in that context, with a focus on improving my own design. That’s how I’m sharing it here as well.
>> How to Get Your Company to Stop Killing Cats
We all have our war stories. But getting a group of people to change is one hell of a thing – that’s why I find it so very cool when it actually works out for the better.
Doesn’t happen often though.
>> Collection Pipeline
A very well put together piece on the power and the breadth collection pipelining operations. Makes me want to do some Clojure today.

5. Pick of the Week
I recently introduced the “Pick of the Week” section here in my “Weekly Review”. The interesting part is that it’s entirely exclusive to my email list subscribers.
So – if you came to this article from my email list, you have the pick already – hope you enjoyed it. If not – feel free to subscribe and you’ll get the next one.
