Number's Group separator and Decimal separator according to local regional format and Vise-versa

Number's  Group separator and Decimal separator  according to local regional format: 


/** @ Returns the number's Group separator according to local regional format */

 /** @ Returns the number's Group separator according to local regional format */
 protected String getGroupSeparator() {
  DecimalFormat decFormat = new DecimalFormat();
  DecimalFormatSymbols decSymbols = decFormat.getDecimalFormatSymbols();
  return String.valueOf(decSymbols.getGroupingSeparator());
 }

/** @ Returns the number Decimal separator according to local regional format */

 /** @ Returns the number Decimal separator according to local regional format */
 protected String getDecimalSeparator() {
  DecimalFormat decFormat = new DecimalFormat();
  DecimalFormatSymbols decSymbols = decFormat.getDecimalFormatSymbols();
  return String.valueOf(decSymbols.getDecimalSeparator());
 }
 

Number with group-separator and decimal-separator convert into decimal number

ie convert the number "4,471.26" into decimal number "4471.26" dis-respective the number format is (for example it could be 4,294,967,295.00  or 4.294.967.295,000  )

public static void geoSp() {
    String a = "4.233,19";
    NumberFormat as = NumberFormat.getInstance();
    double myNumber = 0;
    try {
        myNumber = as.parse(a).doubleValue();
    } catch (ParseException e) {
        e.printStackTrace();
    }
    System.out.println(String.valueOf(myNumber));
}

   gives  Out put :- 4233.19
