This page is a small or partial simulation of what a blind person might experience using a GUI written in Java when very little semantic information is provided. The simulated GUI is never actually seen, but rather is explored or manipuated by typing commands into the command field.
Text appears in the output window.
The goal of this exercise is to try to figure out what the simulated GUI is supposed to do. A Java GUI is constructed out of objects called 'components'. Different types of components are used for buttons, labels, etc. A special type of a component is called a 'container' is used to form groups of components. A container can include any type of component including other containers.
