 public class AdjustmentEvent extends AWTEvent The adjustment event emitted by Adjustable objects likeScrollbarandScrollPane. When the user changes the value of the scrolling component, it receives an instance ofAdjustmentEvent.An unspecified behavior will be caused if the idparameter of any particularAdjustmentEventinstance is not in the range fromADJUSTMENT_FIRSTtoADJUSTMENT_LAST.The typeof anyAdjustmentEventinstance takes one of the following values:-  UNIT_INCREMENT
-  UNIT_DECREMENT
-  BLOCK_INCREMENT
-  BLOCK_DECREMENT
-  TRACK
