Answer 1

• put Icon / ImageIcons to the Queue, Map, Array, List, Vector

• by starting Swing Timer pick up Icon / ImageIcon from the array

• add Icon / ImageIcons to the JLabel, by using JLabel#setIcon()

• code related for Swing GUI should be initialized from invokeLater(), more in the Initial Threads
