Detailed Description

JComboBox. JComboBox is a container, that keeps track of elements added to it by the user. JComboBox allows user to select any item in its list and displays the selected item to the user. JComboBox also can show/hide popup menu containing its list of item whenever the mouse is pressed over it.
