Java Second Job

This time through learning, I mastered the use of drop-down menus and radio buttons
Drop-down menu construction method:
JComboBox ()
Create a JComboBox with a default data model.
JComboBox (ComboBoxModel AModel)
Create a JComboBox whose entries are taken from the existing ComboBoxModel
JComboBox (object[] items)
Creates a JComboBox that contains the elements in the specified array.
JComboBox (vector<?> items)
Creates a JComboBox that contains the elements in the specified Vector.
Radio Button Construction Method:
Jradiobutton ()
Creates a radio button that is initialized to no selection, and its text is not set.
Jradiobutton (Action a)
Creates a radio button whose properties are from the provided Action.
Jradiobutton (icon icon)
Creates a radio button that is initialized to an unchecked selection with the specified image but no text.
Jradiobutton (Icon icon, Boolean selected)
Creates a radio button with the specified image and selection state, but no text.
Jradiobutton (String text)
Creates a radio button with the specified text with a status of not selected.
Jradiobutton (String text, Boolean selected)
Creates a radio button with the specified text and selection state.
Jradiobutton (String Text, icon icon)
Creates a radio button that has the specified text and image and is initialized to no selection.
Jradiobutton (String Text, Icon icon, Boolean selected)
Creates a radio button with the specified text, image, and selection state.

Use buttons, labels, drop-down menus, password boxes, text boxes, radio buttons and other components to write a "test entry" applet
