TimerTask is an abstract class defined in java.util package. TimerTask class defines a task that can be scheduled to run for just once or for repeated number of time. In order to define a TimerTask object, this class needs to be implemented and the run method need to be overriden. The run method is implicitly invoked when a timer object schdedules it to do so.
Note: An instance of TimerTask class is used to define a task the needs to run periodically.
- TimerTask(): Creates a new timer task
public abstract class TimerTask extends Object implements Runnable
- cancel(): java.util.TimerTask.cancel() Cancels this timer task
public boolean cancel() Returns: true if this task is scheduled for one-time execution and has not yet run, or this task is scheduled for repeated execution. Returns false if the task was scheduled for one-time execution and has already run, or if the task was never scheduled, or if the task was already cancelled.
- run(): java.util.TimerTask.run() The action to be performed by this timer task
public abstract void run() Description: The action to be performed by this timer task
- scheduledExecutionTime(): java.util.TimerTask.scheduledExecutionTime() Returns the scheduled execution time of the most recent actual execution of this task
public long scheduledExecutionTime() Returns: the time at which the most recent execution of this task was scheduled to occur, in the format returned by Date.getTime(). The return value is undefined if the task has yet to commence its first execution
