public interface AccessibleValue
```
The AccessibleValue interface should be supported by any object that supports a numerical value (e.g., a scroll bar). This interface provides the standard mechanism for an assistive technology to determine and set the numerical value as well as get the minimum and maximum values. Applications can determine if an object supports the AccessibleValue interface by first obtaining its AccessibleContext (see Accessible) and then calling the AccessibleContext.getAccessibleValue() method. If the return value is not null, the object supports this interface.
