public class DateFormat
ImplementsCloneable
Known subtypesSimpleDateFormat
A class for parsing and formatting localisation sensitive dates, compatible
with Jave 6 SDK. This implementation uses the Codename One localization manager for handling formatting dates. Parsing
dates is not implemented in this class since the localization pattern is not
exposed.
Fields
public static final int FULL = 0 | Constant for full style parsing/formatting pattern. |
public static final int LONG = 1 | Constant for long style parsing/formatting pattern. |
public static final int MEDIUM = 2 | Constant for medium style parsing/formatting pattern. |
public static final int SHORT = 3 | Constant for short style parsing/formatting pattern. |
public static final int DEFAULT = 2 | Constant for default style (MEDIUM) parsing/formatting pattern. |

Throws
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.)
equals
public boolean equals(Object obj)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).
