控制台烟花效果 (ASCII Art)

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};

// 绘制渐变背景
GradientPaint gradient = new GradientPaint(0, 0, Color.WHITE,
400, 400, Color.LIGHT_GRAY);

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";

// 彩带动画

System.out.print("\r");
// 生成彩带效果
StringBuilder sb = new StringBuilder();

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");

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
- 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。
- Swing 动画: 直接运行，Java 标准 GUI 库。
- 文本彩带: 直接运行,纯控制台效果。
- 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。
