Conversion of Integer Arraylist to string

Question

I'm trying to convert the numbers of my Array list into Strings at point i. How do I do this so I can create substrings of my numbers?

ArrayList<Integer> numbers= new ArrayList<Integer>();
for( int i=0; i<=10; i++){
    String numbersString[i] = String.valueOf(numbers[i]);
}

Solution

If numbers[i] is of type Integer you can just use its built in toString() method. However, as numbers is an ArrayList, you need to use numbers.get(i).

String numbersString[i] = ... is invalid syntax. You have to declare your array outside the loop and then access it simply by numbersString[i] = ... inside the loop.
