35 * A layout manager that allows multiple components to be laid out either

37 * example, a vertical arrangement of components will stay vertically
38 * arranged when the frame is resized.

55 * <p> The BoxLayout manager is constructed with an axis parameter that
56 * specifies the type of layout that will be done. There are four choices:
