Issue 275 - EnhancedStream with Dynamic Proxy
In our previous newsletter we enhanced Java 8 Streams by decorating them with an EnhancedStream class. The code had a lot of repetition, which often leads to bugs if written by hand. In this newsletter we use a dynamic proxy to create an EnhancedStream. The resulting code is shorter and more consistent.Issue 274 - EnhancedStream
Java 8 Streams have a rather narrow-minded view of what makes objects distinct. In this newsletter, we enhance Streams to allow a more flexible approach for deciding uniqueness.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.Birthdays
