OrlandoJUG Reading List ::: from JavaSpecialists

Issue 273 - Truly Public Methods

Class.getMethods() returns all the public methods in this class and the classes in its ancestry. However, we cannot necessarily call these methods, for example if they are declared in a private inner class or a lambda. In this newsletter we attempt to find all truly public methods.

Issue 272 - Hacking Enums Revisited

In a previous newsletter, we looked at how we could dynamically add new enums and also rewire affected switch statements. Due to improvements in Java security, our old approach needs to be updated for Java 12.

Issue 271 - HttpClient Executors

Java 11 added the HttpClient to give us a better way to send HTTP requests. It supports asynchronous and synchronous mode. HTTP2 comes out of the box. The threading is a bit funky though and Professor Cay Horstmann explores how things work underneath the covers.

Issue 270 - Excursions into Deduplication

When are Strings deduplicated? How can we find out whether they are of any benefit in our application? How much does it cost in terms of CPU? We try to show you how we can get this from the deduplication statistics provided by the JVM.

Issue 269 - Heterogeneous Comparisons

The compareTo() function has three rules. Break any one of them and you might get an exception when you sort. In this newsletter we explore what these rules are and how they can affect sorting.

Presentation: Big Data's Ethical Drought: The Thirst for More Data Has Led to a Lapse in Ethics and Privacy

Katharine Jarmul provides examples of data (mis)use and asking how we can work with data without violating the trust and privacy of users, producing an ethical product?

By Katharine Jarmul

The Ethical Role Testers Can Have

Testers should step up outside of only doing quality level verification and be the ambassadors of ethical change, said Michal Buczko at TestCon Europe 2019. Ethics and integrity are becoming more and more important. Ensuring that employees understand appropriate ways to address daily ethical issues can have a major impact on your project outcome and your relationship with customers.

By Ben Linders

Article: A First Look at Java Inline Classes

Java currently supports only two types of value: primitives and object references. Project Valhalla extends this by introducing inline classes which are a new form of type that exhibit some behaviors of both. These new types open the door to better alignment with modern CPUs and considerable potential performance improvements for Java applications.
