This Recursion example uses a List Box and a TextField. Enter the value for the size ( no larger than 4 is best..). The output is in the List Box. See the working Applet below.
import java.applet.Applet;
import java.awt.*;
public class RecOutList extends Applet
{
TextField sizeTxt;
List output;
int size;
public void init()
{
sizeTxt = new TextField();
add(sizeTxt);
output = new List(10);
add(output);
}
public void Moves(int s)
{
output.addItem("begin");
if (s<2) output.addItem("base "+s);
else
{
Moves(s-1);
output.addItem("mid "+s);
Moves(s-2);
output.addItem("done "+s);
}
}
public boolean action(Event e,Object o)
{
size = Integer.parseInt(sizeTxt.getText());
Moves(size);
return true;
}
}
