TimerTask for each value of array

[lexikovs]

Hello.

I have problem with printing out the each value of certain array with certain duration of time.
For example I have array with values: "Value1", "Value2", "Value3". I want to output "Value1", after 5 sec "Value2", after 5 second "Value3".
Instead, All Values of arrays are printout 3 times.
If you could help to me, I will be so gratefull ))
Thank you.


Here is my code.
--------------------

import java.util.Date;

public class Timer2 {

	/**
	 * @param args
	 */
	  public static void main(String[] args) { 
		  
	        long start = new Date().getTime(); 
	        
	     
	        
	       for(int i=0; i<4; i++){ 
	            new java.util.Timer().schedule(new java.util.TimerTask(){ 
	            	
	                public void run(){ 
	                	String[] arrayElements = {"value1", "value2", "value3", "value4"};
	                	 for (int i=0; i<arrayElements.length; i++ )
	                    System.out.println(arrayElements[i]); 
	                	 
	                } 
	            },
	            new Date(start)); 
	           start+=1000; 
	        } 
	    }

}

Here are some steps to help you out:

1. get the time
2. calculate the time the task ends i.e. original time + (nOf tasks x 5seconds)
3.i. loop forever
i.e.
boolean timePassed = false;
while (timePassed==false) {
    //loop
    3.ii. if time up, timePassed = true;
}
4. set loop condition
i.e.
//loop
int stepCount = 1;
if (new timeInstance-originalTime == stepCount*5 seconds) {
    //perform action
    ++stepCount;
}
5. set time up condition
if (new timeInstance >= calculation answer from 2.) timePassed = true;

to simplifiy time calculations, use long Calendar.getTimeInMillis();

You could use Timer's scheduleAtFixedRate to repeat things every 1000 ms.

To ozzyman: why not use java.util.Timer and TimerTask?

Much as I hate to give full solutions, this one is brief and is in comparison with your recommendations:

import java.util.Timer;
import java.util.TimerTask;

class Timer2 {

   private static final String[] ARRAY_ELEMENTS = {"value1", "value2", "value3", "value4"};

   public static void main(String[] args) {
      final Timer utilTimer = new Timer();
      utilTimer.scheduleAtFixedRate(new TimerTask() {
         private int index = 0;

         public void run() {
            System.out.println(ARRAY_ELEMENTS[index]);
            index++;
            if (index >= ARRAY_ELEMENTS.length) {
               utilTimer.cancel();
            }
         }
      }, 1000L, 1000L);
   }

}
