Create Empty/Prefilled array

On Click, put number in array and then call a method which updates the textfield, putting out the numbers in the array.

   i have currently done it this way. it doesnt work. i want the array to  make the number appear on the correct position of the textfield. 
 
 

   int counter = 0;
       int[] myArray=null;
 if (e.getSource() == button)
        {
         
  
       textArea.insert("1",myArray[counter]);
  counter++;
   
        }
     
 if (e.getSource() == button_1)
        {
             
            textArea.insert("2",myArray[counter]);
             counter++;
        }
  
 }

Well, looks like you're not understanding my idea. I pseudo-coded it for you:

 

ArrayList<int> numbers = new ArrayList<int>();

function onClick1() { // repeat this for every button, as you already did
	numbers.add(1);
    updateText();
}

// [...]

function updateText() {
	for (int i = numbers.size(); i < 1; i--) {
    	textArea.insert(numbers.get(i));
    }
}
