I just can't get my swimming pool (polygon pool) to fill with water at an angle (polygon water).  

My code so far:-

import java.awt.*;
import java.applet.Applet;
import java.awt.event.*;


//<APPLET code=SwimmingPool.class width=600 height=350> </APPLET>

public class SwimmingPool extends Applet implements AdjustmentListener
{
      private Scrollbar slider;
      private int sliderValue;
      private int currentX;

      public void init()
      {
            Label title1;
            title1 = new Label("Change Pool Volume");
            add(title1);
            slider=new Scrollbar(Scrollbar.HORIZONTAL, 0, 1, 0, 441);
            add(slider);
            slider.addAdjustmentListener(this);
      }

      public void paint(Graphics g)
      {
            int xValues[] = {40, 440, 440, 40};
            int yValues[] = {40, 40, 60, 100};
            Polygon pool = new Polygon(xValues, yValues, 4);
            g.drawPolygon(pool);

            int unit = 1;
            //float unit2 = 0.4f;
            int xValues2[] = {40, 40+ currentX, 40 + currentX, 40};
            int yValues2[] = {40*unit, 40, 100, 100};            
            Polygon water = new Polygon(xValues2, yValues2, 4);
            g.fillPolygon(water);
      }

      public void adjustmentValueChanged(AdjustmentEvent e)
      {
            currentX=slider.getValue();
            repaint();
      }
}

try setting the colour before painting:

g.setColor(Color.blue);

How does that make any difference to your previous result, apart from changing the color?

this has only changed the color - not the scaled "fill".  Still very stuck!

> Still very stuck!

Why didn't you say so :)

 try the following:

double ratio = (400 - currentX) / 400.0;
int yValues2[] = {40, 40, 60 + (int)(40*ratio), 100};

You can just ask them, to change the grade to an "A" ;-)
