Java是一门伟大的程序设计语言，同时，它还是基于Java语言从嵌入式开发到企业级开发的平台。在风起云涌的计算机技术发展历程中，Java 的身影随处可见，而且生命力极其强大。1995 年，Java Applet使得Web网页可以表现精彩和互动的多媒体内容，促进了Web的蓬勃发展。之后随着Web的发展，应用Web成为大型应用开发的主流方式，Java凭借其“一次编译，到处运行”的特性很好地支持了互联网应用所要求的跨平台能力，成为服务器端开发的主流语言。Java EE至今依然是最重要的企业开发服务器端平台。2004年再次产生了对Web客户端体验的强烈需求，促使富因特网应用技术广泛流行，从Java Web Start到现在的JavaFX,都是重要的富因特网应用技术。 现在我们进入了移动互联网时代，而Java依然是当之无愧的主角。作为开发者，想要在互联网时代其中有一席之地，一定需要多学习新的知识。 Java并发编程实战 本书深入浅出地介绍了Java 线程和并发，是一本完美的Java并发参考手册。书中从并发性和线程安全性的基本概念出发，介绍了如何使用类库提供的基本并发构建块，用于避免并发危险、构造线程安全的类及验证线程安全的规则，如何将小的线程安全类组合成更大的线程安全类，如何利用线程来提高并发应用程序的吞吐量，如何识别可并行执行的任务，如何提高单线程子系统的响应性

JavaFX WhatApp-Like ConversationView

由 夙愿已清 提交于 2020-12-01 17:55:17
问题 I'm trying to make a WhatsApp-Like Conversation-View in JavaFX. In order to make the sent messages appear on the right and the received messages appear on the left then I cannot use TextArea. How can I do it? I tried GridPane without TextArea but it didn't make things easier. Moreover, is it a good practice to make controls static? Extra: if you can also help me do the chat bubble behind the text, it would be great. Here is my code: public class ConversationView implements WhatAppView {

java源码学习-JDK14之jpackage命令

鲁班学院 java源码学习- JDK14之jpackage命令 jpackage命令使用场景 使用场景是面向java桌面端程序打包. 可以让windows/mac 直接双击使用java程序,对系统里面有没有jdk/jre不做要求. 在这里,我们先理一下以前java桌面程序是怎么运行的: jdk8及以前 这时候的java客户端程序,主要分两部分, 一部分是可执行jar包, 一部分是电脑里面要装jdk/jre , 然后通过 java -jar XXXXX.jar 来运行程序. jdk9及以后的模块化 这是java模块化的一个分界线,其实jdk9,jdk10,我都没有用过, 我是直接尝试的jdk11. 在模块化的基础上, 项目多了一个文件, moudle-info.java 如下图所示: 如上图,所示,主要是 requires , opens , exports 这三个关键字. requires : 当前模块想要运行的话,需要哪些依赖,相当于在maven引包的基础上,要再声明一遍依赖 opens: 当前模块中的哪些包,可以被反射. 如fxml中要声明处理的controller , 每当fxml加载的时候,都会去新建一个controller实例, 所以需要opens controller的包名给javafx.fxml exports: 当前模块有哪些包,可以被引用.

Trying to add actions to my main menu with Scene Builder and Netbeans and I don't understand why I'm getting a InvocationTargetException

由 余生颓废 提交于 2020-11-30 00:01:39
问题 I was following along with a video from school and I swore I added everything they told me to add but I keep getting problems. The only thing that I can think of is that the person in the video is running Netbeans 8.2 while I am running Netbeans 11 and I know that JavaFX isn't as easy on the newer versions of Netbeans... My project runs until I add actions to my Main Menu buttons and I don't understand why it stops running. This is what my error output says: Exception in Application start
