Scala is an object-oriented language running on Java JVM. It supports function programming and is more flexible in syntax than Java. At the same time, through the Akka library, Scala supports powerful Actor-based multi-thread programming. With these advantages, I recently wanted to use Scala in a new project, but in the new project, we abandoned the common Java a

Unlike previous development tools like Eclipse and NetBeans, Idea's project is quite workspace with Eclipse, and module is the equivalent of project.Here's a correspondence between the concept of Eclipse and idea:Our goal is to create a workspace and then build at least 2 projects under it (2 bar), which is the working space Javaworkspace, contains the JavaOne and javatwo two items.first, review the previous article : IntelliJ idea 14.x integrates wit

If you have two Java projects, how to communicate information to each otherPremise: You must know the IP address and access path of the server to which you want to communicate the Java project (receiving requester).In fact, the communication between the two Java projects is

classes in Java are loaded into the virtual machine by the loader, and that there is a parent-child relationship between the ClassLoader, that is, the child knows the parent, the parent does not know the child, so that the different types of child loading are inaccessible (although they are all placed in the method area), So the loading of resources through the loader of the current class here is guaranteed to be loaded with the same loader as the cl

The way I do it now:1. When configuring Tomcat in Eclipse, choose Create context file instead of Server.xml, the benefit is that the file can be arbitrarily named, consistent with the virtual directory (that is, the attribute path in XML). When Tomcat loads a project, it scans all the XML files in the Conf\catalina\localhost directory and then loads them according to the configuration.The XML file in the Conf\catalina\localhost directory. In general, a project corresponds to an XML file, and if

Java is used to do the project! Java's main area of application is enterprise-level project development! To engage in enterprise-level project development, you need to master the following points: 1, master the basic steps of project development 2, with a strong object-oriented analysis and design skills 3, master use case driven, architecture as the core of the mainstream development method No one wants to be satisfied with their own life to mast

Converting a Java project into a clear UML class diagram makes it easier for us to understand the project structure and dependencies between modules. This article describes six open-source tools that can reverse engineer Java projects to UML class diagrams. 1.Eclipse MDT Model Development Tool (MDT) provides some exemplary tools and development models based on th
