public class ShowRocketTable implements UnitConstants

}
The
main()
method of
ShowRocketTable
sets up default table fonts, creates a Swing
table, and displays it:
public static void main(String[] args)
{
setFonts();
JTable t = new JTable(getRocketTable());
t.setRowHeight(36);
JScrollPane jsp = new JScrollPane(t);
jsp.setPreferredSize(
new java.awt.Dimension(300, 100));
display(jsp, " Rockets");
}
The
setFonts()
methods establishes the fonts to use for table cells and column headers:
private static void setFonts()
{
Font f = new Font("Dialog", Font.PLAIN, 18);
UIManager.put("Table.font", f);
UIManager.put("TableHeader.font", f);
}
The
getRocketTable()
method returns a
RocketTable
object that fulfills the role of a
TableModel
. Essentially, the
RocketTable
object adapts a (row, column) request into a
(rocket, attribute) request:
private static RocketTable getRocketTable()
{
Rocket r1 = new Rocket(
"Shooter", 3.95, (Length) METER.times(50));
Rocket r2 = new Rocket(
"Orbit", 29.95, (Length) METER.times(5000));
return new RocketTable(new Rocket[] { r1, r2 });
}
The
display()
method contains reusable code:
