控制台烟花效果 (ASCII Art)

import java.util.Random;
import java.util.concurrent.TimeUnit;
public class ConsoleFireworks {
    public static void main(String[] args) throws InterruptedException {
        Random random = new Random();

        String reset = "\033[0m";
        System.out.println("\n🎆 Java 庆祝烟花 🎆\n");
        for (int i = 0; i < 10; i++) {
            // 随机选择颜色
            String color = colors[random.nextInt(colors.length)];
            // 随机生成烟花形状
            int height = random.nextInt(5) + 3;
            int width = random.nextInt(7) + 5;

            System.out.print("\033[H\033[2J");
            System.out.flush();
            // 打印烟花
            for (int row = 0; row < height; row++) {
                for (int col = 0; col <= width * 2; col++) {
                    if (row == 0 || row == height - 1 || col == 0 || col == width * 2) {
                        System.out.print(color + "*" + reset);
                    } else {
                        System.out.print(" ");
                    }
                }
                System.out.println();
            }
            // 随机延迟
            TimeUnit.MILLISECONDS.sleep(400 + random.nextInt(600));
        }
        System.out.println("\n🎉 庆祝完成！ 🎉");
    }
}

Swing 图形界面庆祝动画

import javax.swing.*;
import java.awt.*;
import java.util.Random;
public class CelebrationSwing extends JPanel {
    private final String[] messages = {
        "🎉 恭喜！", "🎊 庆祝！", "🌟 成功！", "🏆 奖杯！", "🎈 气球队！"
    };
    private final int[] messageX = new int[5];
    private final int[] messageY = new int[5];
    private final Color[] colors = {Color.RED, Color.GREEN, Color.BLUE, Color.MAGENTA, Color.ORANGE};
    private final Random random = new Random();
    public CelebrationSwing() {
        // 初始化消息位置
        for (int i = 0; i < messages.length; i++) {
            messageX[i] = random.nextInt(400);
            messageY[i] = random.nextInt(300);
        }
        // 动画定时器
        Timer timer = new Timer(100, e -> {
            // 更新位置（向上飘动）
            for (int i = 0; i < messages.length; i++) {
                messageY[i] -= 2;
                if (messageY[i] < -50) {
                    messageY[i] = 400;
                    messageX[i] = random.nextInt(400);
                }
            }
            repaint();
        });
        timer.start();
    }
    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2d = (Graphics2D) g;
        // 绘制渐变背景
        GradientPaint gradient = new GradientPaint(0, 0, Color.WHITE,
                400, 400, Color.LIGHT_GRAY);
        g2d.setPaint(gradient);
        g2d.fillRect(0, 0, 400, 400);
        // 绘制庆祝文字
        g2d.setFont(new Font("微软雅黑", Font.BOLD, 20));
        for (int i = 0; i < messages.length; i++) {
            g2d.setColor(colors[i]);
            g2d.drawString(messages[i], messageX[i], messageY[i]);
        }
        // 绘制中心庆祝文字
        g2d.setFont(new Font("微软雅黑", Font.BOLD, 30));
        g2d.setColor(Color.RED);
        g2d.drawString("🎉 JAVA 庆祝 🎉", 100, 200);
    }
    public static void main(String[] args) {
        JFrame frame = new JFrame("庆祝案例 - Swing");
        CelebrationSwing celebration = new CelebrationSwing();
        frame.add(celebration);
        frame.setSize(400, 400);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}

纯文本彩带庆祝效果

public class TextCelebration {
    public static void main(String[] args) throws InterruptedException {
        String[] emojis = {"🎉", "🎊", "⭐", "🎈", "🏆", "🎁", "💖", "🎀"};
        String message = "Java庆祝案例";
        String border = "=".repeat(40);
        System.out.println(border);
        System.out.println("        🎉 庆祝案例 🎉");
        System.out.println(border);
        System.out.println();
        // 彩带动画
        for (int frame = 0; frame < 20; frame++) {
            System.out.print("\r");
            // 生成彩带效果
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < 10; i++) {
                int idx = (frame + i) % emojis.length;
                sb.append(emojis[idx]).append(" ");
            }
            System.out.print(sb.toString());
            System.out.print("  " + message + "  ");
            System.out.print(sb.reverse().toString());
            Thread.sleep(200);
        }
        System.out.println("\n");
        System.out.println(border);
        System.out.println("         🎉 庆祝完成！ 🎉");
        System.out.println(border);
    }
}

使用 JavaFX 的烟花效果（需要 JavaFX 支持）

import javafx.animation.KeyFrame;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.canvas.Canvas;
import javafx.scene.canvas.GraphicsContext;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
import javafx.util.Duration;
import java.util.Random;
public class JavaFXFireworks extends Application {
    private static final int WIDTH = 600;
    private static final int HEIGHT = 500;
    private final Random random = new Random();
    @Override
    public void start(Stage stage) {
        Canvas canvas = new Canvas(WIDTH, HEIGHT);
        GraphicsContext gc = canvas.getGraphicsContext2D();
        // 动画循环
        Timeline timeline = new Timeline(
            new KeyFrame(Duration.millis(100), e -> drawFrame(gc))
        );
        timeline.setCycleCount(Timeline.INDEFINITE);
        timeline.play();
        stage.setScene(new Scene(new StackPane(canvas), WIDTH, HEIGHT));
        stage.setTitle("JavaFX 烟花庆祝");
        stage.show();
    }
    private void drawFrame(GraphicsContext gc) {
        // 清屏
        gc.setFill(Color.BLACK);
        gc.fillRect(0, 0, WIDTH, HEIGHT);
        // 绘制随机烟花
        gc.setFill(randomColor());
        gc.setStroke(randomColor());
        gc.setLineWidth(2);
        int x = random.nextInt(WIDTH);
        int y = random.nextInt(HEIGHT);
        int radius = random.nextInt(30) + 10;
        // 绘制烟花
        gc.strokeOval(x - radius, y - radius, radius * 2, radius * 2);
        gc.fillOval(x - 3, y - 3, 6, 6);
        // 绘制庆祝文字
        gc.setFill(Color.WHITE);
        gc.setFont(javafx.scene.text.Font.font("Arial", 30));
        gc.fillText("🎉 庆祝！", 200, 250);
    }
    private Color randomColor() {
        return Color.color(random.nextDouble(), random.nextDouble(), random.nextDouble());
    }
    public static void main(String[] args) {
        launch(args);
    }
}

运行说明

1. 控制台烟花: 直接运行，需要在支持 ANSI 颜色的终端（如 Git Bash、Linux/Mac 终端）中运行。
2. Swing 动画: 直接运行，Java 标准 GUI 库。
3. 文本彩带: 直接运行,纯控制台效果。
4. JavaFX 烟花: 需要 JavaFX 库支持（Java 11+ 需额外添加模块）。

这些案例展示了 Java 在不同场景下的庆祝效果,可以根据需要选择适合的版本。
