Java compact1, compact2, compact3 java.time.format Enum SignStyle（JDK8）

Enum Constant Detail

• NORMAL

  public static final SignStyle NORMAL

  Style to output the sign only if the value is negative.

  In strict parsing, the negative sign will be accepted and the positive sign rejected. In lenient parsing, any sign will be accepted.

• ALWAYS

  public static final SignStyle ALWAYS

  Style to always output the sign, where zero will output '+'.

  In strict parsing, the absence of a sign will be rejected. In lenient parsing, any sign will be accepted, with the absence of a sign treated as a positive number.

• NEVER

  public static final SignStyle NEVER

  Style to never output sign, only outputting the absolute value.

  In strict parsing, any sign will be rejected. In lenient parsing, any sign will be accepted unless the width is fixed.

• NOT_NEGATIVE

  public static final SignStyle NOT_NEGATIVE

  Style to block negative values, throwing an exception on printing.

  In strict parsing, any sign will be rejected. In lenient parsing, any sign will be accepted unless the width is fixed.

• EXCEEDS_PAD

  public static final SignStyle EXCEEDS_PAD

  Style to always output the sign if the value exceeds the pad width. A negative value will always output the '-' sign.

  In strict parsing, the sign will be rejected unless the pad width is exceeded. In lenient parsing, any sign will be accepted, with the absence of a sign treated as a positive number.

Method Detail

• values

  public static SignStyle[] values()

  Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

  for (SignStyle c : SignStyle.values())
      System.out.println(c);
  

  Returns:

  an array containing the constants of this enum type, in the order they are declared

• valueOf

  public static SignStyle valueOf(String name)

  Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

  Parameters:

  name - the name of the enum constant to be returned.

  Returns:

  the enum constant with the specified name

  Throws:

  IllegalArgumentException - if this enum type has no constant with the specified name

  NullPointerException - if the argument is null
