This document discusses GUI and event handling in Java. It begins by introducing GUI components like frames, panels, buttons, labels, text fields, lists, scroll panes, checkboxes, comboboxes and menus. It then covers various layout managers including flow, border, grid and gridbag layouts. Finally, it discusses event handling in Java by adding event listeners to components to trigger actions when events like button clicks occur.
