Method Details

formatWithThousandsSeparator

public static String formatWithThousandsSeparator(long value,
 char thousandsSeparator)

Converts the specified long value to a string using the specified thousands separator.

Usually one can use NumberFormat for this purpose, but this class is overloaded with different aspects to parse and format a lot of different things, making it inefficient and resource intensive.

This method is optimized for this single use case to save time and resources.

It is approximately 5 times faster than NumberFormat.format(long) on a prepared NumberFormat -instance and approximately 10 times faster than creating a NumberFormat-instance and formatting then (like NumberFormat.getInstance().format()).

Parameters:

value - value to format

thousandsSeparator - thousands separator to use

Returns:

formatted string for the specified long value
