无法找到符号 - 方法fillArc（INT，INT，INT，INT，INT，INT）

public class MyComponent extends JComponent

    { 

     // declares the 2D Graphics object and a Rectangle 
     Graphics2D g2; 


     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); 
    } 
} 

所以我将承担错误意味着fillArc是不是在我已经导入了类中列出的方法，但我已经检查了API及其在那里，我也检查了类的拼写，所以Idk做什么

我有眼睛的瞳孔作为我想填写的弧的参考点的圆圈，但我甚至无法玩定位，直到我有东西出现。

Ellipse2D.Double类中没有fillArc()方法。可能您应该在Graphics对象上调用此方法：

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