Class SimpleDateFormat

All Implemented Interfaces:
Cloneable

public class SimpleDateFormat extends DateFormat

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.

  • Method Details

    • isRestrictMonthNameLength

      public static boolean isRestrictMonthNameLength()
      Returns
      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
      • restrict: @param restrict true to truncate localized month names to the length requested by the pattern, false to 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
      • newSymbols: new format symbols.
    • applyPattern

      public void applyPattern(String pattern)

      Apply a new pattern.

      Parameters
      • pattern: the pattern to set
    • equals

      public boolean equals(Object o)
      Description copied from class: Object
      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).
      Overrides:
      equals in class DateFormat
    • 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.)
