    <p>I am having a problem with a project.</p> <p>So basically what I have is a class Shape with some sub-class ( ShapeRectangle, ShapeTriangle, etc ). In each sub-class, I got an outputShape method: g.fillRect(getX(), getY(), getWidth(), getHeight());</p> <p>In another class, showShapes, I got an array that contains the sub-classes.</p> <p>I would like to run the method via the array.</p> <p>Is there any way to do it?</p> <p>EDIT: The array in showShapes is a Shape[] array.</p> <p>Here are the code of ShapeRect ( sorry, bits are in french ): import java.awt.Color; import java.awt.Graphics;</p> <pre><code>public class FormeRectangulaire extends Forme { public FormeRectangulaire(int x, int y, int width, int height){ setX(x); setY(y); setWidth(width); setHeight(height); setColor(Color.RED); } public void afficherForme(Graphics g){ g.setColor(getColor()); g.fillRect(getX(), getY(), getWidth(), getHeight()); } } </code></pre> <p>Here is the shape: import java.awt.Color; import java.awt.Graphics;</p> <pre><code>public class Forme { private int x; private int y; private int width; private int height; private Color color; /*public void afficherForme(Graphics g){ afficherForme(g); }*/ public int getX() { return x; } public void setX(int x) { this.x = x; } public int getY() { return y; } public void setY(int y) { this.y = y; } public Color getColor(){ return color; } public void setColor(Color color){ this.color = color; } public int getWidth() { return width; } public void setWidth(int width) { this.width = width; } public int getHeight() { return height; } public void setHeight(int height) { this.height = height; } } </code></pre> <p>And here is how I put each class inside the array:</p> <pre><code> public void creerArrayFormes(){ String[][] donnes = getDatas(); if(donnes[getDatasElement()][0].equals("CARRE") || donnes[getDatasElement()][0].equals("RECTANGLE")){ FormeRectangulaire rect = new FormeRectangulaire(Integer.parseInt(donnes[getDatasElement()][1]),Integer.parseInt(donnes[getDatasElement()][2]),Integer.parseInt(donnes[getDatasElement()][3]),Integer.parseInt(donnes[getDatasElement()][4])); setFormes(rect, getDatasElement()); } } </code></pre>

    1. CODoes Shape declare outputShape as an abstract method? If not, why not?

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.
