The DateField class is used to display, edit, or input date and/or time into a MIDlet A DateField class is instantiated by specifying a label for the field, a field mode, and a time zone, although time zone is optional Table 6-3 lists the available DateField modes Both methods are illustrated in the following two statements:

DateField Modes

High-Level Display: Screens
setDate() method The setDate() method requires one parameter, which is an instance of the Date class containing the date/time value that will appear in the date field The getDate() method is called to retrieve the date/time value of the date field You can use the date/time value in a number of ways within your MIDlet, such as in a calculation Listing 6-9 contains the JAD file for Listing 6-10, which illustrates how to place a date/time value into a date field and read a date/time value from a date field that is later used in a calculation Besides storing and retrieving date/time values using DateField class methods, you can also replace the DateField mode and retrieve the DateField mode of an instance of a DateField class You ll find these methods handy to use whenever you need to change the mode on the fly The setInputMode() method replaces the existing DateField mode with the mode passed as a parameter to the setInputMode() method The getInputMode() method is used to retrieve the mode of an instance of a DateField

Creating and Manipulating an Instance of a DateField Object
The example in Listing 6-10 creates an instance of the DateField class that is initialized with current date and time of the system s clock, which is displayed on the screen (Figure 6-4)

J2ME: The Complete Reference
Creating an Instance of the DateField Class
Listed here are the steps required to create an instance of the DateField class: 1 Declare references
2 Obtain a reference to the instance of the Display class 3 Create an instance of the Form class 4 Create an instance of the DateField class 5 Set the instance of the DateField class to the system s date 6 Create an instance of a Command class to exit the MIDlet 7 Associate the instance of the DateField class to the instance of the Form class 8 Associate the instance of the Command class to the instance of the Form class 9 Associate a CommandListener with the instance of the Form class 10 Display the instance of the Form class containing the system s date on the screen 11 Evaluate the command selected by the user 12 If the Exit command is selected, terminate the MIDlet
You ll notice that, like other listings in this chapter, Listing 6-10 begins by declaring references to instances of classes that are used in the MIDlet These classes are instantiated in the constructor and assigned to variables The instance of the DateField class is placed in the DATE_TIME mode since both date and time are displayed The date and time is set by passing the Date() construction a date/time value in milliseconds since January 1, 1970 The SystemcurrentTimeMillis() method returns the current time in milliseconds the number of milliseconds since January 1, 1970 The instance of the DateField class, along with the Exit commands and the CommandListener, are then associated with the instance of the Form class The form is then displayed on the screen by calling the setCurrent() method within the startApp() method After the user selects the Exit command, the device s application manager calls the commandAction() method, where the command is evaluated The MIDlet terminates when the user selects the Exit command
