One of the methods of the Timer class is the int purge() method. The purge() method removes all the canceled tasks from the timer’s task queue. Invoking this method does not affect the behavior of the timer, rather it eliminates references to the canceled tasks from the queue. The purge() method came into existence since JDK 1.5.The purge() method acts as a medium for space-time tradeoff where it trades time for space. More specifically, the time complexity of the method is proportional to n + c log n, where n is the number of tasks in the queue and c ... Read More
The hypot() function is used to calculate the hypotenuse of a right-angle triangle. It Returns the length of the hypotenuse in float. Of a right-angled triangle, the longest side is hypotenuse.Syntaxhypot(a, b)Parametersa − Length of first sideb − Length of second sideReturnThe hypot() function Returns the length of the hypotenuse in float.Example Live DemoOutput8.24621125123538.5440037453175
The is_finite() function checks if a value is finite or not. It Returns true if num is a finite number, else it Returns false.Syntaxis_finite(num)Parametersnum − The number to be checked.ReturnThe is_finite() function Returns true if num is a finite number, else it Returns false.Example Live DemoOutput1Let us see another example −Example Live DemoOutput
The is_infinite() function checks if a value is infinite or not. It Returns true if num is an infinite number, else it Returns false.Syntaxis_infinite(num)Parametersnum − The number to be checked.ReturnThe is_infinite() function Returns true if num is an infinite number, else it Returns false.ExampleExample Live DemoOutput1
The atan() function return the arc tangent of a number. It returns a float, which is a numeric value between -Pi/2 and Pi/2 radians.Syntaxatan(val)Parametersval − The value for which you want to get the arc tangent.ReturnThe atan() function returns the arc tangent of a number.Example Live DemoOutput1.5208379310731.10714871779410.54041950027058-0.54041950027058
One of the methods in the Timer class is the void schedule(Timertask task, Date time) method. This method schedules the specified task for execution at the specified time. If the time is in the past, it schedules the task for immediate execution.Declaration −The java.util.Timer.schedule(Timertask task, Date time) is declared as follows −public void schedule(Timertask task, Date time)There are few exceptions thrown by the schedule(Timertask task, Date time) method. They are as follows −IllegalArgumentExceptionThis exception is thrown if time.getTime() is negativeIllegalStateExceptionThis exception is thrown if task was scheduled or cancelled beforehand, timer was cancelled, or timer thread terminated.NullPointerExceptionThis exception is thrown ...
