int[] numbersToFormat = new int[]
  { 1, 10, 100, 10000, 100000, 1000000, 10000000, 100000000, 1000000000 };


for (int number : numbersToFormat) {
  System.out.println(  
    NumberFormat.getNumberInstance(Locale.getDefault()).format(number));
}

10
100
10,000
100,000
1,000,000
10,000,000
100,000,000
1,000,000,000

Answer 2

Add this function in common class

  public static String getFormatedNumber(String number){
        if(!number.isEmpty()) {
            double val = Double.parseDouble(number);
            return NumberFormat.getNumberInstance(Locale.US).format(val);
        }else{
            return "0";
        }
    }

And use that function every where like this:

String newNumber = Utils.getFormatedNumber("10000000");
