This Java program allows users to select multiple colors from a list and copy the selected colors to another list using a button.
It demonstrates the usage of JList with multiple selection and how to transfer data between lists within a graphical user interface (GUI) built using Swing.
Select multiple items from a list of color names.
Copy selected items from the first list to a second list by clicking a button.
Handles multiple item selections using MULTIPLE_INTERVAL_SELECTION.
JList: Displays color names and copies selected items to another list.
JButton: Triggers the action to copy selected items.
Container: Manages the layout of the GUI components.
ActionListener: Handles the button click event to copy selected items.
The first JList (colorList) displays a list of color names.
The user selects multiple colors from this list.
When the "Copy >>>" button is clicked, an ActionListener is triggered.
The selected colors are copied from colorList to the second JList (copyList), updating the second list with the selected values.
