        // declares the 2D Graphics object and a Rectangle

        Ellipse2D.Double outerFace = new Ellipse2D.Double(100,150,300,350);
        Line2D.Double mouth = new Line2D.Double(200,400,300,400);
        Ellipse2D.Double leftOuterEye = new Ellipse2D.Double(150,275,50,50);
        Ellipse2D.Double rightOuterEye = new Ellipse2D.Double(250,275,50,50);
        Ellipse2D.Double leftPupil = new Ellipse2D.Double(150,285,25,25);
        Ellipse2D.Double rightPupil = new Ellipse2D.Double(250,285,25,25);
        Line2D.Double leftEyeLine = new Line2D.Double(150,300,200,300);
        Line2D.Double rightEyeLine = new Line2D.Double(250,300,300,300);


        leftPupil.fillArc(75, 100, 200, 200, 90, 270);

        rightPupil.fillArc(75, 100, 200, 200, 90, 270);


        g2 = (Graphics2D) g;
        g2.draw(outerFace);
        g2.draw(mouth);
        g2.draw(leftOuterEye);
        g2.draw(rightOuterEye);
        g2.draw(leftPupil);
        g2.draw(rightPupil);
        g2.draw(leftEyeLine);
        g2.draw(rightEyeLine);
    }
}

所以我认为错误意味着fillArc不是我导入的类中列出的方法，但是我检查了API及其那里，我也检查了类的拼写，所以Idk是什么做

我为眼睛的瞳孔设置圆圈作为我想要填充的弧线的参考点，但我甚至无法使用定位，直到我得到一些东西出现。

Answer 1

fillArc()课程中没有Ellipse2D.Double方法。您可能应该在Graphics对象上调用此方法：

g.fillArc(75, 100, 200, 200, 90, 270);

找不到符号 - 方法fillArc（int，int，int，int，int，int）
