Java – how to escape a string to be passed to decimalformat

Can I know how to escape a string to decimal format?

// currencySymbolPrefix can be any string.
NumberFormat numberFormat = new DecimalFormat(currencySymbolPrefix + "#,##0.00");

How to avoid currencysymbolprefix so that it may contain any character containing '#' and will not be interpreted as one of the modes

Please don't suggest

NumberFormat numberFormat = new DecimalFormat("#,##0.00");
final String output = currencySymbolPrefix + numberFormat.format(number);

Because my supplier's method only accepts a single numberformat

Solution

You can use apostrophes to refer to:

String pattern = "'" + currencySymbolPrefix + "'#,##0.00";
NumberFormat numberFormat = new DecimalFormat(pattern);

If the currentysymbolprefix itself may contain apostrophes, you need to escape by doubling them:

String pattern = "'" + currencySymbolPrefix.replace("'","''") + "'#,##0.00";
