Original: Programming with Typesafe enums and annotations in Java 5Annotations--java annotationsYou may encounter this requirement: Annotate your Java application by associating it with metadata that describes the data of other data. Java has been providing an instant annotation (ad hoc annotation) mechanism through the transient keyword, which allows you to identify a member variable that should be ignored during serialization. However, until JAVA5 f

Scala eclipse sbt Application Development Scala has a relatively complete Eclipse IDE (Scala IDE for Eclipse). for developers who do not want to migrate from eclipse to the Iea platform, it is particularly important to compile and package Scala applications in Eclipse to develop Scala applications conveniently, quickly, and effectively. Sbt is a building tool similar to Maven. We will use it to build the publishing program. This article describes how to build an Eclipse Scala application and how

Original: http://www.codeaffine.com/2015/03/04/map-distinct-value-types-using-java-generics/Occasionally the average developer runs into a situation where he had to map values of arbitrary types within a particular Container. However the Java collection API provides container related parameterization only. Which limits the type safe usage of for HashMap example to a single value type. But what if you want to mix apples and pears?Luckily there is a easy design pattern the allows to map distinct

programming, Chinese-language called reactive programming. Other technologies quickly followed, as ES6 introduced a similar asynchronous programming approach through Promise. The Java community has not lagged much behind, and Netflix and Typesafe have provided RxJava and Akka Stream technology, allowing the Java platform to have a framework for reactive programming. In fact, earlier, the NIO framework like Mina and Netty can actually handle high-conc
