文章目录 前言什么是Java GUI一、打开IDEA 新建一个Maven项目(后续可以打包、引入相关依赖也很容易)二、引入依赖三.绘制UI界面四.绘制JPanel面板总结 前言 什么是Java GUI Java UI即Java用户界面是指使用Java编程语言创建的图形用户界面GUI。Java提供了多种工具和技术来创建和管理用户界面使得开发者能够构建具有丰富交互性和吸引力的应用程序。 在Java中用于构建UI的主要库和框架包括 SwingSwing是Java平台标准版Java SE的一部分它提供了一组丰富的GUI组件和布局管理器用于构建跨平台的桌面应用程序。Swing组件包括按钮、文本框、标签、滑块等以及更复杂的组件如表格和树形结构。 JavaFXJavaFX是一个用于构建富客户端应用程序的图形和媒体库。它提供了现代化的UI组件、动画、Web集成和媒体支持。与Swing相比JavaFX更加现代和灵活适用于构建复杂的用户界面和多媒体应用程序。 AWTAWTAbstract Window Toolkit是Java中最早的GUI工具包提供了基本的窗口、按钮和文本框等组件。然而随着Swing和JavaFX的出现AWT的使用逐渐减少但仍在一些旧的或特定的应用程序中使用。 在构建Java UI时开发者通常会遵循以下步骤 设计界面首先开发者需要设计应用程序的用户界面确定所需的组件、布局和交互方式。 选择库和框架根据应用程序的需求和目标平台选择适合的Java UI库和框架。 创建组件使用所选库和框架提供的API创建所需的UI组件并设置它们的属性如大小、颜色、字体等。 布局管理使用布局管理器来组织和管理组件在界面上的位置和大小。Java提供了多种布局管理器如边界布局、网格布局和流式布局等。 事件处理为组件添加事件监听器以便在用户与界面交互时执行相应的操作如点击按钮、选择菜单项等。 测试和调试在开发过程中不断测试和调试UI确保其正常运行并符合设计要求。 通过Java UI技术开发者可以创建出功能强大、外观美观的应用程序提供丰富的用户体验。这些应用程序可以运行在桌面、移动设备或其他Java支持的平台上。 上图是制作成功的效果图 通过A、D来控制蓝色人物前进防御和后退J、K、L来控制拳、防御、踢腿 红色人物对应的是左箭头、右箭头以及1、2、3. 制作这个小游戏 作者打算用2篇博文来分享整个过程 本文作为一个引入 一、打开IDEA

{warPanel.mastercancel(e.getKeyCode());warPanel.mancancel(e.getKeyCode());} } 四.绘制JPanel面板 JPanel是Java Swing库中的一个关键组件它提供了许多优点使得开发者能够更高效地创建复杂的图形用户界面(GUI)。以下是JPanel的一些主要优点 轻量级容器JPanel是一个轻量级的容器这意味着它使用了本地窗口系统的较少资源因此更加高效。轻量级组件的绘制通常比重量级组件更快并且更易于管理。 灵活的布局管理JPanel允许使用各种布局管理器来控制其内部组件的布局。例如你可以使用FlowLayout、BorderLayout、GridLayout等这使得开发者能够轻松地排列和调整组件的位置和大小以满足不同的界面设计需求。 嵌套和组合JPanel可以嵌套在其他Swing容器中如JFrame、JDialog等这使得开发者能够创建复杂的界面结构。通过组合多个JPanel你可以实现更精细的界面布局和组件组织。 事件处理JPanel支持事件监听器使得开发者能够响应用户与界面的交互如按钮点击、鼠标移动等。这使得应用程序能够更加响应用户的操作提供更好的用户体验。 自定义绘制JPanel提供了绘制自定义图形、图像或文本的功能。你可以通过重写paintComponent方法来实现自定义绘制逻辑从而创建独特的视觉效果。 易于扩展和集成由于JPanel是Swing库的一部分它与其他Swing组件具有良好的集成性。此外由于其开源性质开发者可以根据需要扩展JPanel的功能以满足特定的应用需求。 综上所述JPanel作为Java Swing库中的一个核心组件具有轻量级、灵活布局、嵌套组合、事件处理、自定义绘制以及易于扩展和集成等优点使得开发者能够高效地创建复杂的图形用户界面。 package src;import javazoom.jl.player.Player; import sun.audio.AudioPlayer; import sun.audio.AudioStream;import
