本篇文章给大家带来《java小游戏代码》，石家庄人才网对文章内容进行了深度展开说明，希望对各位有所帮助，记得收藏本站。

Java 是一种面向对象的编程语言，它可以用来开发各种应用程序，包括游戏。Java 游戏代码可以使用各种库和框架来编写，例如 Swing、AWT、LibGDX 和 jMonkeyEngine。Swing 和 AWT 是 Java 自带的 GUI 工具包，可以用来创建简单的 2D 游戏。LibGDX 和 jMonkeyEngine 是第三方游戏引擎，可以用来创建更复杂的 2D 和 3D 游戏。

以下是一个简单的 Java 小游戏代码示例，它使用 Swing 工具包创建了一个简单的弹球游戏：

```javaimport javax.swing.*;import java.awt.*;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.awt.event.KeyEvent;import java.awt.event.KeyListener;public class BallGame extends JFrame implements ActionListener, KeyListener { private static final long serialVersionUID = 1L; private int ballX = 150; private int ballY = 50; private int ballSize = 20; private int paddleX = 100; private int paddleWidth = 60; private int paddleSpeed = 10; private int ballXSpeed = 2; private int ballYSpeed = 2; private boolean gameRunning = true; public BallGame() { super("弹球游戏"); setSize(400, 400); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setLocationRelativeTo(null); setResizable(false); addKeyListener(this); setFocusable(true); setFocusTraversalKeysEnabled(false); Timer timer = new Timer(10, this); timer.start(); setVisible(true); } public void paint(Graphics g) { super.paint(g); Graphics2D g2d = (Graphics2D) g; // 绘制背景 g2d.setColor(Color.black); g2d.fillRect(0, 0, getWidth(), getHeight()); // 绘制球 g2d.setColor(Color.white); g2d.fillOval(ballX, ballY, ballSize, ballSize); // 绘制挡板 g2d.setColor(Color.white); g2d.fillRect(paddleX, 350, paddleWidth, 10); } @Override public void actionPerformed(ActionEvent e) { if (gameRunning) { moveBall(); checkCollision(); } repaint(); } private void moveBall() { ballX += ballXSpeed; ballY += ballYSpeed; } private void checkCollision() { // 碰撞检测 if (ballX + ballSize > getWidth() || ballX < 0) { ballXSpeed = -ballXSpeed; } if (ballY < 0) { ballYSpeed = -ballYSpeed; } if (ballY + ballSize > getHeight()) { gameRunning = false; JOptionPane.showMessageDialog(this, "游戏结束！"); System.exit(0); } if (ballY + ballSize > 350 && ballX > paddleX && ballX < paddleX + paddleWidth) { ballYSpeed = -ballYSpeed; } } @Override public void keyPressed(KeyEvent e) { if (e.getKeyCode() == KeyEvent.VK_LEFT) { paddleX -= paddleSpeed; if (paddleX < 0) { paddleX = 0; } } if (e.getKeyCode() == KeyEvent.VK_RIGHT) { paddleX += paddleSpeed; if (paddleX + paddleWidth > getWidth()) { paddleX = getWidth() - paddleWidth; } } } @Override public void
