java - "error: reached end of file while parsing"

Question

所以我的 AP Comp Sci 实验室要求我构建和删除，这是我的删除代码，我发现了错误，

错误:解析时到达文件末尾

希望得到一些帮助，谢谢。 显然，还有很多代码，如果有帮助，我可以添加它，没有问题。

   public void erase(Graphics g, int f)
   {
     frame = f;
     if (frame == 1)
     { 
         //First
         g.drawRect(50,50,100,100);
         g.drawLine(70,70,70,100);
         g.drawLine(120,70,120,100);
         g.drawLine(70,125,100,125);
     }
     
     if (frame == 2)
     {
         //Second - Left Eye Gone
         g.drawRect(150,50,100,100);
         g.drawLine(220,70,220,100);
         g.drawLine(170,125,200,125);
     }
     
     if (frame = 3)
     {
         //Third - Right Eye Gone
         g.drawRect(250,50,100,100);
         g.drawLine(270,70,270,100);
         g.drawLine(270,125,300,125);
     }
     
     if (frame == 4)
     {
         //Fourth - Mouth Gone
         g.drawRect(350,50,100,100);
         g.drawLine(370,70,370,100);
         g.drawLine(420,70,420,100);
     }
     
     if (frame == 5)
     {
         //Fifth - Mouth and Left Eye
         g.drawRect(450,50,100,100);
         g.drawLine(520,70,520,100);          
     }
     
     if (frame == 6)
     {
         //Sixth - Mouth and Right Eye
         g.drawRect(550,50,100,100);
         g.drawLine(570,70,570,100);
     }
   }

当我在某处缺少括号时，我收到此错误消息，但看起来这些都在这里说明了。我会检查文件的其余部分，并确保您没有在其他地方缺少括号。
