Java.util.Timer Class

Introduction

The java.util.Timer class provides facipty for threads to schedule tasks for future execution in a background thread.

This class is thread-safe i.e multiple threads can share a single Timer object without the need for external synchronization.

This class schedules tasks for one-time execution, or for repeated execution at regular intervals.

All constructors start a timer thread.

Following is the declaration for java.util.Timer class −

pubpc class Timer
   extends Object

Sr.No.	Constructor & Description
1	Timer() This constructor creates a new timer.
2	Timer(boolean isDaemon) This constructor creates a new timer whose associated thread may be specified to run as a daemon.
3	Timer(String name) This constructor creates a new timer whose associated thread has the specified name.
4	Timer(String name, boolean isDaemon) This constructor creates a new timer whose associated thread has the specified name, and may be specified to run as a daemon.

Sr.No.	Method & Description
1	void cancel() This method terminates this timer, discarding any currently scheduled tasks.
2	int purge() This method removes all cancelled tasks from this timer s task queue.
3	This method schedules the specified task for execution at the specified time.
4	This method schedules the specified task for repeated fixed-delay execution, beginning at the specified time.
5	This method schedules the specified task for execution after the specified delay.
6	This method schedules the specified task for repeated fixed-delay execution, beginning after the specified delay.
7	This method schedules the specified task for repeated fixed-rate execution, beginning at the specified time.
8	This method Schedules the specified task for repeated fixed-rate execution, beginning after the specified delay.

This class inherits methods from the following classes −
