public class FormattableUtils extends Object
Provides utilities for working with the Formattable interface.
The Formattable interface provides basic control over formatting
 when using a Formatter. It is primarily concerned with numeric precision
 and padding, and is not designed to allow generalised alternate formats.

public FormattableUtils()
FormattableUtils instances should NOT be constructed in
 standard programming. Instead, the methods of the class should be invoked
 statically.
This constructor is public to permit tools that require a JavaBean instance to operate.
