public class SimpleDateFormat
- Object
- Format
- DateFormat
- SimpleDateFormat
ImplementsCloneable
A class for parsing and formatting dates with a given pattern, compatible with the Java 6 API, as in the examples here: https://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html
To localize the formatted dates, see the discussion Format a localized date in Codename One.
Constructors
public SimpleDateFormat() | Construct a SimpleDateFormat with no pattern. |

Method details
isRestrictMonthNameLength
public static boolean isRestrictMonthNameLength()Returns
true if localized month names should be truncated to the
requested pattern length.setRestrictMonthNameLength
public static void setRestrictMonthNameLength(boolean restrict)Enables or disables truncating of localized month names so that they
match the number of pattern characters that triggered their lookup.
Parameters
restrictbooleantrueto truncate localized month names to the length requested by the pattern,falseto keep the platform provided value as-is (default behaviour).
toPattern
public String toPattern()Returns
the pattern
getDateFormatSymbols
public DateFormatSymbols getDateFormatSymbols()Get the date format symbols for parsing/formatting textual components of
dates in a localization sensitive way.
Returns
current symbols.
setDateFormatSymbols
public void setDateFormatSymbols(DateFormatSymbols newSymbols)Apply new date format symbols for parsing/formatting textual components
of dates in a localisation sensitive way.
Parameters
newSymbolsDateFormatSymbols- new format symbols.
applyPattern
public void applyPattern(String pattern)Apply a new pattern.
Parameters
patternString- the pattern to set
equals
public boolean equals(Object o)Indicates whether some other object is “equal to” this one.
The equals method implements an equivalence relation: It is reflexive: for any reference value x, x.equals(x) should return true. It is symmetric: for any reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true. It is transitive: for any reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true. It is consistent: for any reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the object is modified. For any non-null reference value x, x.equals(null) should return false.
The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any reference values x and y, this method returns true if and only if x and y refer to the same object (x==y has the value true).
hashCode
public int hashCode()Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.
The general contract of hashCode is: Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result. It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
clone
public Object clone()setTimeZone
public void setTimeZone(TimeZone zone)Sets the time zone the date’s fields are formatted in, as java.text.DateFormat
does. Without one the device’s default zone is used.
A formatter fixed to the device zone cannot print an instant’s fields in any other: a UTC time had to be moved onto a local one first, and inside a daylight-saving gap that local time does not exist, so its hour came out shifted.
Parameters
zoneTimeZone- the zone, or null for the device’s default
getTimeZone
public TimeZone getTimeZone()The zone set with
setTimeZone, or the zone captured at construction when
none was set.Returns
the zone fields are formatted in
format
public String format(Date source)Format a given date.
Parameters
sourceDate- date to be formatted.
Returns
formatted date.
parse
public Date parse(String source)
throws ParseExceptionParses text from a string to produce a Date.
