Internationalization and Formatting numbers

Internationalization and Formatting numbers

You can consider Java to be a strong language with respect to internationalization and number formatting. Sometimes you might wish to format numbers in a specific locale or given a certain number of digits. Two classes help in this case: NumberFormat and DecimalFormat. For example, to format a specific number in a given LOCALE (French, for example) try:

 String numberString=NumberFormat.getInstance(locale.FRENCH).format(number);

Or to round to two decimal places try:

 NumberFormat format = NumberFormat.getInstance();format .setMaximumDecimalFractionDigits(2);String numberString = format .format(number + 0.5);

You can also use the getCurrencyInstance method of NumberFormat to manipulate currency values.
