| Three packages comprise the Abstract Window Toolkit: java.awt, java.awt.image, and java.awt.peer. |
| AWT Package |
| The java.awt package provides GUI elements used to get input from and display information to the user such as windows, buttons, scrollbars, and text items. |
| AWT Image Package |
| The java.awt.image package contains classes and interfaces for managing image data, such as setting the color model, cropping, color filtering, setting pixel values, and grabbing snapshots of the screen. |
| AWT Peer Package |
| The java.awt.peer package contains classes and interfaces that connect platform-independent AWT components to their platform-dependent implementation (such as Motif widgets or Microsoft Windows controls). |
