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:
Swing:Swing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。
JavaFX:JavaFX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。
AWT:AWT(Abstract 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。

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 新建一个Maven项目(后续可以打包、引入相关依赖也很容易)
建完之后的整体结构如下:
二、引入依赖
因为需要播放MP3格式的背景音乐于是要引入相关依赖:
在pom.xml中添加下面的代码
<dependencies><dependency><groupId>javazoom</groupId><artifactId>jlayer</artifactId><version>1.0.1</version></dependency></dependencies>
三.绘制UI界面
代码如下:
package src;
import javazoom.jl.player.Player;
import sun.audio.AudioPlayer;
import sun.audio.AudioStream;
import javax.swing.*;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;
public class UI extends JFrame implements KeyListener {WarPanel warPanel=new WarPanel();Player player;public UI(){this.setTitle("赤色妖精花2.0");this.setLocation(0,0);this.setSize(1024,680);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);this.setVisible(true);this.add(warPanel);this.addKeyListener(this);warPanel.action();}public static void main(String[] args) {UI ui=new UI();ui.init();}public void init(){while(true){try{InputStream resourceAsStream = this.getClass().getClassLoader().getResourceAsStream("music/bgm12.mp3");playmusic(resourceAsStream);Thread.sleep(82800);}catch (Exception e){e.printStackTrace();}}}public void playmusic(InputStream inputStream) throws Exception{
// BufferedInputStream bufferedInputStream=new BufferedInputStream(inputStream);player=new Player(inputStream);player.play();}public void playmusic(String music) throws Exception{BufferedInputStream bufferedInputStream=new BufferedInputStream(new FileInputStream(music));player=new Player(bufferedInputStream);player.play();}public void sound(String str){try {FileInputStream in = new FileInputStream(str);AudioStream as=newAudioStream(in);AudioPlayer.player.start(as);}catch(Exception e){e.printStackTrace();}
}public void sound(InputStream inputStream){try {AudioStream as=newAudioStream(inputStream);AudioPlayer.player.start(as);}catch(Exception e){e.printStackTrace();}}@Overridepublic void keyTyped(KeyEvent e) {}@Overridepublic void keyPressed(KeyEvent e) {
// System.out.println(e.getKeyCode());warPanel.restart(e.getKeyCode());warPanel.manmove(e.getKeyCode());warPanel.mastermove(e.getKeyCode());}@Overridepublic void keyReleased(KeyEvent e) {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。
