Difference between Thread and Timer

[Raja ji]

Hi to all,

Can anybody tell me what is the differece between Timer and Thread.
When to use Timer and when to use Thread.

hi,

You can start the timer on some specific time but not in case of thread.
Thread can implements Singleton(to make low heapSize).

A Timer is essentially a thread scheduled for execution at one ore more specific times. If you look at the API for TimerTask (which is what gets scheduled), you'll see that it is just about the same as Thread.
