Java integer list

Question

I am trying to make java go trough a list of numbers. It chooses the first one, gives this as output, waits/sleeps like 2000 milliseconds and then give the next one as output, waits 2000 milliseconds, etc.

They should not be listed behind eachother so when my list is: 10 20 30 40 50

It should not give as output: 10 20 30 40 50. But just 50.

It would be even better if it was able to repeat itself.

So far i tried:

List<Integer> myCoords = new ArrayList<Integer>(); myCoords.add(10); myCoords.add(20); myCoords.add(30); myCoords.add(40); myCoords.add(50); Iterator<Integer> myListIterator = someList.iterator();  while (myListIterator.hasNext()) {     Integer coord = myListIterator.next();      } 

But this has no timer, and i am not sure if this will only show '20' or '10 20 30 40 50' as output. And i dont really know how to put a sleep/wait command and a repeat command in this :s (might have overlooked the repeat command if its already in)

Edit Tyvm all, i can go on with the rest of the coding now :)

Answer 1

If you want to rewrite a line on console, print a control character \r (carriage return).

List<Integer> myCoords = new ArrayList<Integer>(); myCoords.add(10); myCoords.add(20); myCoords.add(30); myCoords.add(40); myCoords.add(50); Iterator<Integer> myListIterator = myCoords.iterator();  while (myListIterator.hasNext()) {     Integer coord = myListIterator.next();          System.out.print("\r");     System.out.print(coord);     Thread.sleep(2000); } 

Answer 2

code that works, but output is:

10 20 30 40 50 

so:

    List<Integer> myCoords = new ArrayList<Integer>();     myCoords.add(10);     myCoords.add(20);     myCoords.add(30);     myCoords.add(40);     myCoords.add(50);     for (Integer number : myCoords) {         System.out.println(number);         try {             Thread.sleep(2000);         } catch (InterruptedException e) {             e.printStackTrace();         }     }
