我的朋友和我正在进行爱情计算器项目，我们很难在javax swing中画出一颗心。有人可以帮助我们吗？谢谢！我正在为整个测验添加代码。 （该测验由3个班级构建..） 我想在第一页和最后一页添加心形 我们确实已经添加了实际问题，将来会添加。我们只是初学者，对于这个成熟的代码感到抱歉。

这可以通过在java中使用StdDraw库来完成，其中 标准绘图使我们可以在java应用程序中使用图形。
为了画一颗心，你应该首先画一颗钻石。然后在钻石的左上角和右上角画两个圆圈。 :) StdDraw在以下代码中绘制依赖关系。以下代码将提供一个漂亮的粉红色心脏。
public class Heart {
public static void main(String[] args) {
StdDraw.setXscale(-1.5, +1.5);
StdDraw.setYscale(-1.5, +1.5);
StdDraw.setPenColor(StdDraw.PINK);
// draw the diamond first
double[] xs = { -1, 0, 1, 0 };
double[] ys = { 0, -1, 0, 1 };
StdDraw.filledPolygon(xs, ys);
// circles
StdDraw.filledCircle(+0.5, 0.5, 1 / Math.sqrt(2));
StdDraw.filledCircle(-0.5, 0.5, 1 / Math.sqrt(2));
}
}
