Active Visual Scaffolding by Charles Kelemen and Eugene Turk
Another interesting animation is:
The student does not have to work too hard to generate it:
<![CDATA[
public class StudentArray {
static int size = 8;
static int[] testArray = {9, 53, 3, 8, 15, 13, 24, 17};
public static void main(String args[]) {
int lowval, lowpoint, left, temp;
ArrayGUI window = new ArrayGUI();
window.inAnApplet = false;
window.setArraySize(size);
window.setArray(testArray);
window.initArray();
window.pack();
window.setVisible(true);
for (left=0; left<size; left++) {
lowpoint = left;
lowval = testArray[left];
for (int i = left + 1; i < size; i++) {
if (window.lessthan(i, lowpoint)) {
lowval = testArray[i];
lowpoint = i;
}
}
temp = testArray[left];
testArray[left] = testArray[lowpoint];
testArray[lowpoint] = temp;
window.redraw();
}
}
}
