Class DecimalFormatSymbols

java.lang.Object
  java.text.DecimalFormatSymbols

All Implemented Interfaces:

Serializable, Cloneable

---

public final class DecimalFormatSymbols
extends Object
implements Cloneable, Serializable

This class represents the set of symbols (such as the decimal separator, the grouping separator, and so on) needed by DecimalFormat to format numbers. DecimalFormat creates for itself an instance of DecimalFormatSymbols from its locale data. If you need to change any of these symbols, you can get the DecimalFormatSymbols object from your DecimalFormat and modify it.

See Also:

Locale, DecimalFormat, Serialized Form

Parameters:

currency - the new currency to be used

Throws:

NullPointerException - if currency is null

Since:

1.4

See Also:
