Assignment #7 CSI205 Assigned: 11/19/09
Due: 12/01/09
Write a class definition named GUIClock that extends JFrame and contains the following GUI controls:
6 labels (“Month”, “Day”, “Year”, “Hour”, “Minute”,”Second”), 6 ComboBoxes, 1 Botton (“Set”), and
1 uneditable TextField. You should have one Combobox for Month name (“January”, “February”,….., “December”),
one for Day numbers (0-31), one for Year Numbers (1980-2020), one for Hours (0-23), one for Minutes (0-59) and one for Seconds (0-59).
Each ComboBox should have a maximum row count of one. After the user selects values from these Comboboxes and clicks the Set button, your
application should collect the values from the Comboboxes and attempt to instantiate a Clock object from Assignment #6 with these values.
If the object instantiation is successful, you should display the return value of Clocks toString() method in the textfield. Otherwise, display
“Invalid Date/Time” in the textfield. You should use the GridLayout manager to arrange your controls (8 x 2), and use additional “blank” labels
to improve the presentation of your layout.
You should create a client application named GUITestClock to instantiate a GUIClock object. This application should EXIT_ON_CLOSE.
You should submit the GUIClock.java and GUITestClock.java with the following command:
turnin-csi205 -c csi205 GUIClock.java GUITestClock.java
As usual, you should fully comment each file and each variable.
