A JComboBox is a component that displays a drop-down list and gives users options that we can select one and only one item at a time whereas a JList shows multiple items (rows) to the user and also gives an option to let the user select multiple items.
JComboBox inherits JComponent class .
u can make ur jcombobox uneditable by calling its setEnabled(false). A JComboBox is unEditable by default. You can make it editable with the setEditable(boolean) command. If you are talking about enabled or disabled you can set that by the setEnabled(boolean) method.
This action listener gets the newly selected item from the combo box, uses it to compute the name of an image file, and updates a label to display the image. The combo box fires an action event when the user selects an item from the combo box's menu.
use setMaximumRowCount() to display as many rows as you want in the popup.
