Class DecimalStyle

java.lang.Object

java.time.format.DecimalStyle

public final class DecimalStyle
extends Object

Localized decimal style used in date and time formatting.

A significant part of dealing with dates and times is the localization. This class acts as a central point for accessing the information.

Implementation Requirements:

This class is immutable and thread-safe.

Field Details

STANDARD

public static final DecimalStyle STANDARD

The standard set of non-localized decimal style symbols.

This uses standard ASCII characters for zero, positive, negative and a dot for the decimal point.

Method Details

getAvailableLocales

public static Set<Locale> getAvailableLocales()

Lists all the locales that are supported.

At a minimum, the returned Set must contain a Locale instance equal to Locale.ROOT and a Locale instance equal to Locale.US.

Returns:

a Set of Locales for which localization is supported

ofDefaultLocale

public static DecimalStyle ofDefaultLocale()

Obtains the DecimalStyle for the default FORMAT locale.

This method provides access to locale sensitive decimal style symbols.

This is equivalent to calling of(Locale.getDefault(Locale.Category.FORMAT)).

Returns:

the decimal style, not null

See Also:

• Locale.Category.FORMAT

of

public static DecimalStyle of(Locale locale)

Obtains the DecimalStyle for the specified locale.

This method provides access to locale sensitive decimal style symbols. If the locale contains "nu" (Numbering System) and/or "rg" (Region Override) Unicode extensions, returned instance will reflect the values specified with those extensions. If both "nu" and "rg" are specified, the value from the "nu" extension supersedes the implicit one from the "rg" extension.

Parameters:

locale - the locale, not null

Returns:

the decimal style, not null

getZeroDigit

public char getZeroDigit()

Gets the character that represents zero.

The character used to represent digits may vary by culture. This method specifies the zero character to use, which implies the characters for one to nine.

Returns:

the character for zero

withZeroDigit

public DecimalStyle withZeroDigit(char zeroDigit)

Returns a copy of the info with a new character that represents zero.

The character used to represent digits may vary by culture. This method specifies the zero character to use, which implies the characters for one to nine.

Parameters:

zeroDigit - the character for zero

Returns:

a copy with a new character that represents zero, not null

getPositiveSign

public char getPositiveSign()

Gets the character that represents the positive sign.

The character used to represent a positive number may vary by culture. This method specifies the character to use.

Returns:

the character for the positive sign

withPositiveSign

public DecimalStyle withPositiveSign(char positiveSign)

Returns a copy of the info with a new character that represents the positive sign.

The character used to represent a positive number may vary by culture. This method specifies the character to use.

Parameters:

positiveSign - the character for the positive sign

Returns:

a copy with a new character that represents the positive sign, not null

getNegativeSign

public char getNegativeSign()

Gets the character that represents the negative sign.

The character used to represent a negative number may vary by culture. This method specifies the character to use.

Returns:

the character for the negative sign

withNegativeSign

public DecimalStyle withNegativeSign(char negativeSign)

Returns a copy of the info with a new character that represents the negative sign.

The character used to represent a negative number may vary by culture. This method specifies the character to use.

Parameters:

negativeSign - the character for the negative sign

Returns:

a copy with a new character that represents the negative sign, not null

getDecimalSeparator

public char getDecimalSeparator()

Gets the character that represents the decimal point.

The character used to represent a decimal point may vary by culture. This method specifies the character to use.

Returns:

the character for the decimal point

withDecimalSeparator

public DecimalStyle withDecimalSeparator(char decimalSeparator)

Returns a copy of the info with a new character that represents the decimal point.

The character used to represent a decimal point may vary by culture. This method specifies the character to use.

Parameters:

decimalSeparator - the character for the decimal point

Returns:

a copy with a new character that represents the decimal point, not null

equals

public boolean equals(Object obj)

Checks if this DecimalStyle is equal to another DecimalStyle.

Overrides:

equals in class Object

Parameters:

obj - the object to check, null returns false

Returns:

true if this is equal to the other date
