Constructor Detail

public DialogProgram()

Creates a new dialog program.

Usage:

DialogProgram program = new DialogProgram();

Method Detail

public void init()

Specifies the code to be executed as startup time before the run method is called. Subclasses can override this method to perform any initialization code that would ordinarily be included in an applet init method. In general, subclasses will override init in GUI-based programs where the program simply sets up an initial state and then waits for events from the user. The run method is required for applications in which there needs to be some control thread while the program runs, as in a typical animation.

Usage:

program.init();

public void run()

Specifies the code to be executed as the program runs. The run method is required for applications that have a thread of control that runs even in the absence of user actions, such as a program that uses console interation or that involves animation. GUI-based programs that operate by setting up an initial configuration and then wait for user events usually do not specify a run method and supply a new definition for init instead.
