How do I join together arcs and lines in a single Shape???

Question

I am out of my depth, I am probably missing something spectacular .... I need to construct a shape from arcs and lines to get something like this, only closed:
Like a winding river sort of thing... I do not need to draw this I need to have this shape and its area available to me.... How do I join these two arcs and two lines into a shape from which I can find - area.contains(xy.getX(), xy.getY()); , preatty please?
here is the code that causes numerous errors:
import java.awt.*;
import java.awt.Graphics.*;
import java.awt.Graphics2D.*;
import java.awt.geom.RectangularShape.*;
import java.awt.geom.Arc2D;
import java.awt.geom.Line2D;
import java.awt.geom.Rectangle2D;
import java.awt.geom.Area;
import java.awt.geom.GeneralPath;
class MyShapes //extends Arc2D
public static Arc2D outerOne;
public static Arc2D innerOne;
public static Line2D upLine, bottomLine;
public static Area area = new Area();
public MyShapes(double[] upper, double [] lower)
outerOne.setArc(upper[0], upper[1], upper[2], upper[3], upper[4], upper[5], (int)upper[6]);
//                         x,          y,               w,          h,               OA,      AA, int OPEN =1
innerOne.setArc(lower[0], lower[1], lower[2], lower[3], lower[4], lower[5], (int)lower[6]);
//outerTR=this.makeClosedShape(outerTopRightArc,middleTopRightArc);
upLine     = new Line2D.Double(outerOne.getX(),outerOne.getY(),innerOne.getX(),innerOne.getY());
bottomLine = new Line2D.Double(outerOne.getX()+outerOne.getWidth(),outerOne.getY()+outerOne.getHeight(),innerOne.getX()+innerOne.getWidth(),innerOne.getY()+innerOne.getHeight());
area = this.joinAll(outerOne,innerOne, upLine, bottomLine);     
private Area joinAll(Arc2D out, Arc2D in, Line2D one, Line2D two)
GeneralPath joiner = new GeneralPath(out);
joiner.append(in, true);
joiner.append(one, true);
joiner.append(two, true);      
Area temp = new Area(joiner);
return temp;     
public boolean isInArea(Point xy)
return area.contains(xy.getX(), xy.getY());     
public boolean isItClosed()
return area.isSingular();     
Thanks

Glad to hear you find what was wrong. Still, it doesn't the main problem : why is that method crashing?
Here is what I've done in the mean time. See if it fits your purpose.import javax.swing.*;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.geom.*;
public class MyShapes {
     private Arc2D outerOne;
     private Arc2D innerOne;
     private Shape line1;
     private Shape line2;
     public MyShapes(double[] upper, double[] lower) {
          outerOne = new Arc2D.Double(upper[0],
                                             upper[1],
                                             upper[2],
                                             upper[3],
                                             upper[4],
                                             upper[5],
                                             0);
          innerOne = new Arc2D.Double(lower[0],
                                             lower[1],
                                             lower[2],
                                             lower[3],
                                             lower[4],
                                             lower[5],
                                             0);
          line1 = new Line2D.Double(outerOne.getStartPoint().getX(),
                                          outerOne.getStartPoint().getY(),
                                          innerOne.getStartPoint().getX(),
                                          innerOne.getStartPoint().getY());
          line2 = new Line2D.Double(outerOne.getEndPoint().getX(),
                                          outerOne.getEndPoint().getY(),
                                          innerOne.getEndPoint().getX(),
                                          innerOne.getEndPoint().getY());
     public void paint(Graphics2D aGraphics2D) {
          aGraphics2D.draw(outerOne);
          aGraphics2D.draw(innerOne);
          aGraphics2D.draw(line1);
          aGraphics2D.draw(line2);
     public static void main(String[] args) {
          double [] XO= {56, 58, 400, 280, 90, 90};// outter arc
          double [] XI={114, 105, 300, 200, 90, 90}; // inner arc
          final MyShapes myShapes = new MyShapes(XO, XI);
          JPanel panel = new JPanel() {
               protected void paintComponent(Graphics g) {
                    super.paintComponent(g);
                    Graphics2D g2 = (Graphics2D)g;
                    myShapes.paint(g2);
          final JFrame frame = new JFrame("Test shape");
          frame.addWindowListener(new WindowAdapter() {
               public void windowClosing(WindowEvent e) {
                    System.exit(0);
          frame.setContentPane(panel);
          SwingUtilities.invokeLater(new Runnable() {
               public void run() {
                    frame.show();
