Java Timing Functions

                         HOW TO USE JAVA TIMER

Java Timer tasks are the scheduled tasks for the program, they are intented to be executed on a specific interval of times or on a specific time  such as this :

There is a Timer class that we will create and it will contain a class to be executed in a specific intervals.

Timer timer = new Timer();

timer.scheduleAtFixedRate(new Go(), 0,20000);

first we created timer and we attached a schedule that is 20000 ms will be 20 seconds to the Go class.

Go class is special because it is extends the TimerTask which will have a function called run()

public class Go extends TimerTask{

        public void run(){

        //This code will be run

}

}

also you can define a delay time before execute in schedule through this parameter

timer.scheduleAtFixedRate(new Go(),DELAY,20000);
