public Second (Date time, TimeZone zone)

This constructor is deprecated.
As of 1.0.13, use the constructor that specifies the locale also.

Creates a new second based on the supplied time and time zone.

Parameters
time the instant in time.
zone the time zone.

public Second (Date time, TimeZone zone, Locale locale)

Creates a new second based on the supplied time and time zone.

Parameters
time the time (null not permitted).
zone the time zone (null not permitted).
locale the locale (null not permitted).

Public Methods

public int compareTo (Object o1)

Returns an integer indicating the order of this Second object relative to the specified object: negative == before, zero == same, positive == after.

Parameters
o1 the object to compare.
Returns
  • negative == before, zero == same, positive == after.

public boolean equals (Object obj)

Tests the equality of this object against an arbitrary Object.

This method will return true ONLY if the object is a Second object representing the same second as this instance.

Parameters
obj the object to compare (null permitted).
Returns
  • true if second and minute of this and the object are the same.

public long getFirstMillisecond (Calendar calendar)

Returns the first millisecond of the minute.

Parameters
calendar the calendar/timezone (null not permitted).
Returns
  • The first millisecond.
Throws
NullPointerException if calendar is null.

public long getFirstMillisecond ()

Returns the first millisecond of the second. This will be determined relative to the time zone specified in the constructor, or in the calendar instance passed in the most recent call to the peg(Calendar) method.

Returns
  • The first millisecond of the second.
See Also

public long getLastMillisecond (Calendar calendar)

Returns the last millisecond of the second.

Parameters
calendar the calendar/timezone (null not permitted).
Returns
  • The last millisecond.
Throws
NullPointerException if calendar is null.

public long getLastMillisecond ()

Returns the last millisecond of the second. This will be determined relative to the time zone specified in the constructor, or in the calendar instance passed in the most recent call to the peg(Calendar) method.

Returns
  • The last millisecond of the second.
See Also

public Minute getMinute ()

Returns the minute.

Returns
  • The minute (never null).

public int getSecond ()

Returns the second within the minute.

Returns
  • The second (0 - 59).

public long getSerialIndex ()

Returns a serial index number for the minute.

Returns
  • The serial index number.

public int hashCode ()

Returns a hash code for this object instance. The approach described by Joshua Bloch in "Effective Java" has been used here:

Returns
  • A hash code.

public RegularTimePeriod next ()

Returns the second following this one.

Returns
  • The second following this one.

public static Second parseSecond (String s)

Creates a new instance by parsing a string. The string is assumed to be in the format "YYYY-MM-DD HH:MM:SS", perhaps with leading or trailing whitespace.

Parameters
s the string to parse.
Returns
  • The second, or null if the string is not parseable.

public void peg (Calendar calendar)

Recalculates the start date/time and end date/time for this time period relative to the supplied calendar (which incorporates a time zone).

Parameters
calendar the calendar (null not permitted).

public RegularTimePeriod previous ()

Returns the second preceding this one.

Returns
  • The second preceding this one.
