    <p>Basically my entire program is to have shapes move across a JFrame, and the problem I am having is that I cannot get my object to move.</p> <p>I have a class called Creatures and the constructor creates my body and tail of my fish. (I'm making an aquarium). This class extends to another class that has a move() method, so that everytime a timer event happens the picture moves. </p> <p>Again my problem is that I cannot get the picture/shape/object to move. If anyone could lend a hand I would be most grateful =]</p> <p>Here is the full class of Creatures</p> <pre><code>import java.awt.geom.Ellipse2D; import java.awt.Color; import java.awt.Polygon; import java.awt.Graphics2D; public class Creatures extends Moveable2DShape{ private Color color; private int delay, number; private int xPos2, yPos2; private final int POINTS = 3; private int []x = new int[POINTS]; private int []y = new int[POINTS]; private double width, height; Ellipse2D.Double body; Polygon tail; public Creatures(int xPos, int yPos, int shapeWidth, int shapeHeight, int bwidth, int bheight, double xSpeed, double ySpeed, Color c){ super(xPos, yPos, shapeWidth, shapeHeight, bwidth, bheight, xSpeed, ySpeed); color = c; xPos2 = xPos; yPos2 = yPos; width = shapeWidth; height = shapeHeight; } public Polygon triangle(int xPos, int yPos){ x[0] = xPos + 100; x[1] = x[0]; x[2] = (int)(xPos + width/2); y[0] = (int)(yPos + (height)); y[1] = yPos; y[2] = (int)(yPos + height/2); tail = new Polygon(x,y,POINTS); return tail; } //public void move(){ } public void draw(Graphics2D g){ body = new Ellipse2D.Double(xPos2, yPos2, width, height); //System.out.println(xPos2 + " " + yPos2 + " " + width + " " + height); triangle(xPos2, yPos2); g.setColor(color); g.fill(body); g.fill(tail); } } </code></pre> <p>I'm supposed to override the move() method that is inherited from the Moveabled2DShape class but i havent yet because I just wanted to test out the method before overriding it. But now my problem is that I need to update xPos2 and yPos2</p>

    1. COI think that we need a bit more information to be able to help you in any meaningful way. You don't show any code that suggests it's the source of the problem for one. Have you added debug statements to your code? For more suggestions on what we need, please check out: [How to Ask Smart Questions](http://catb.org/~esr/faqs/smart-questions.html)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
