    .

    --- Update ---

    I would like to put a delay in my code but for loop conflicts with my timer.
    timer = new Timer(300, new ActionListener()
            {
                public void actionPerformed(ActionEvent e) 
                {
     
                	//textArea.setText("");     
                     for (int i = 1; i < 60; i++)
                     {               	
                     	String format = "%-10s";
                    	String someline;
                     	someline = String.format(format, new Object[]{"Number" + "      " + (i) + " : " + Growth_numbers1[i] + "      " + "repeats"} );      
                     	textArea.append(someline + "\n");
                     }
     
     
                }
            });

    Explain the conflict. Code comments would be helpful to others reading your code (and to you) so that they can understand what the code fragment you posted is supposed to do.

    The conflict is between my timer delay and my for loop. When I take this statment --> textArea.append(someline + "\n"); <--- out of the for loop and place it outside the brackets. My delay timer seems to work ok, but then my array does not get printed out the way I wanted it to be printed out. If I leave this statement in the for loop then all my content gets printed out and it keeps looping and looping and there is no delay except a loop delay that loops and loops.

    So the current error I have is this... Everything gets printed out at once and then it loops again.
    Number 1 : 6 repeats
    Number 2 : 10 repeats
    Number 3 : 4 repeats
    Number 4 : 4 repeats
    Number 5 : 7 repeats
    Number 6 : 2 repeats
    Number 7 : 4 repeats
    Number 8 : 6 repeats
    Number 9 : 4 repeats
    Number 10 : 5 repeats
    Number 1 : 6 repeats <===looped again here
    Number 2 : 10 repeats
    Number 3 : 4 repeats
    Number 4 : 4 repeats
    Number 5 : 7 repeats
    Number 6 : 2 repeats
    Number 7 : 4 repeats
    Number 8 : 6 repeats
    Number 9 : 4 repeats
    Number 10 : 5 repeats
    Number 1 : 6 repeats <===looped again here
    Number 2 : 10 repeats
    Number 3 : 4 repeats
    Number 4 : 4 repeats
    Number 5 : 7 repeats
    Number 6 : 2 repeats
    Number 7 : 4 repeats
    Number 8 : 6 repeats
    Number 9 : 4 repeats
    Number 10 : 5 repeats
    <===looping process continues
    -------------------------------------------------------------------------------------------
    This is what I actually want to do with my code and not have it loop:

    Number 1 : 6 repeats
    delay 100 miliseconds
    Number 2 : 10 repeats
    delay 100 miliseconds
    Number 3 : 4 repeats
    delay 100 miliseconds
    Number 4 : 4 repeats
    delay 100 miliseconds
    Number 5 : 7 repeats
    delay 100 miliseconds
    Number 6 : 2 repeats
    delay 100 miliseconds
    Number 7 : 4 repeats
    delay 100 miliseconds
    Number 8 : 6 repeats
    delay 100 miliseconds
    Number 9 : 4 repeats
    delay 100 miliseconds
    Number 10 : 5 repeats
    etc
    etc
    etc

    So the problem lies between my for loop and the timer delay. How can I go about fixing this?

    Thanks

    It's hurting my head. You have a loop inside a timer's ActionListener.actionPerformed() method that will execute every time the timer lapses. Each time the actionPerformed() method executes, the for() loop starts over. That's what you've programmed it to do, but now you're complaining that that's not what you want. I don't understand what you want it to do, but I'm not sure what you want needs a for() loop. It looks like all you need is a counter from 1 to whatever that increments each time the actionPerformed() method executes, and I don't understand where 'x repeats' and the 'delay x ms' comes from, but those should be possible without the for() loop.

            timer = new Timer(300, new ActionListener()
            {
                public void actionPerformed(ActionEvent e) 
                {
     
                	//textArea.setText("");     
                     //for (int i = 1; i < 73; i++)
                       int count = 0;
                       if (count <= 73)
                       {
                    	count = count + 1;
                    	String format = "%-10s";
                    	String someline;
                     	someline = String.format(format, new Object[]{"Number" + "      " + (count) + " : " + Growth_numbers1[count] + "      " + "repeats"} );      
                     	textArea.append(someline + "\n");
                       }
     
     
     
                }
            });


    ok, you were right about the counter, but it only prints the first element in the Array. How can I get it to print out the rest?

    Of course.
    Each time your timer is activated your counter is set to 0. So you will obviously always print the first element.

    You have to keep your counter variable as a field outside of the timer.
