https://www.javaspecialists.eu The Java(tm) Specialists' Newsletter features advanced articles and tips surrounding the Java Programming Language en Copyright 2000-2020, Dr Heinz Max Kabutz Dr Heinz Kabutz Dr Heinz Kabutz 1440 https://www.javaspecialists.eu/archive/Issue275.html Sat, 23 Nov 2019 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. https://www.javaspecialists.eu/archive/Issue274.html Fri, 22 Nov 2019 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. https://www.javaspecialists.eu/archive/Issue273.html Tue, 1 Oct 2019 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. https://www.javaspecialists.eu/archive/Issue272.html Sat, 7 Sep 2019 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. https://www.javaspecialists.eu/archive/Issue271.html Wed, 21 Aug 2019 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. https://www.javaspecialists.eu/archive/Issue270.html Fri, 31 May 2019 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.
