java爱心特效代码

在Java中创建爱心特效通常涉及到绘制形状，可以使用Swing库或者JavaFX来实现。这里是一个简单的JavaFX例子，使用Shape类和Path来绘制一个爱心：

import javafx.scene.canvas.Canvas;
import javafx.scene.paint.Color;
import javafx.scene.shape.Path;
import javafx.scene.shape.Shape;

public class LoveHeartShape {
    private static final double HEART_WIDTH = 100;
    private static final double HEART_HEIGHT = 165;

    public void drawLoveHeart(Canvas canvas) {
        Path path = new Path();
        path.setFill(Color.RED); // 设置颜色

        path.moveTo(-HEART_WIDTH / 4, -HEART_HEIGHT / 2);
        path.lineTo(HEART_WIDTH / 4, -HEART_HEIGHT / 2);
        path.quadraticCurveTo(0, -HEART_HEIGHT * 0.7, HEART_WIDTH / 8, -HEART_HEIGHT / 2);
        path.lineTo(HEART_WIDTH, 0);
        path.quadraticCurveTo(HEART_WIDTH / 8, HEART_HEIGHT / 2, 0, HEART_HEIGHT);
        path.lineTo(-HEART_WIDTH / 8, HEART_HEIGHT / 2);
        path.quadraticCurveTo(0, HEART_HEIGHT * 0.7, -HEART_WIDTH / 4, HEART_HEIGHT / 2);
        path.closePath();

        Shape heart = path.createFillRuleShape(); // 使用非零规则填充内部
        heart.setStroke(Color.TRANSPARENT); // 不设边框

        canvas.getGraphicsContext2D().drawShape(heart, 0, 0); // 绘制到canvas上
    }
}

要在JavaFX应用中显示这个爱心，你需要将`LoveHeartShape`放入`Scene`并在`Stage`上显示。
