## 18.54 java.awt.Scrollbar (JDK 1.0)

###

This `Component` represents a graphical scrollbar. `setValue()` sets the displayed value of the scrollbar. `setValues()` sets the displayed value, the page size, and the minimum and maximum values. The constants `HORIZONTAL` and `VERTICAL` are legal values for the scrollbar orientation.

    public class Scrollbar extends Component implements Adjustable {
        // Public Constructors
                public Scrollbar();
                public Scrollbar(int orientation);
                public Scrollbar(int orientation, int value, int visible, int minimum, int maximum);
