A
graphical user interface (GUI)
is the modern alternative to terminal
I/O that allows a program to communicate with its user. In a GUI, a window
application is created. Some of the ways to perform input include selection
from a list of alternatives, pressing buttons, checking boxes, typing in text
fields, and using the mouse. Output can be performed by writing into text
fields as well as drawing graphics. In Java 1.2 or higher, GUI programming
is performed by using the
Swing
package.
