Constructor Detail


public ConsoleProgram()
Creates a new console program.

Method Detail


protected IOConsole createConsole()
Creates the console used by the ConsoleProgram.

createConsole in class Program
The console to be used by the program


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.

init in class Program


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.

Specified by:
run in interface Runnable
run in class Program


public void setFont(Font font)
Sets the font for the console.

setFont in class Container
font - The new font


public void setFont(String str)
Sets the font used for the console as specified by the string str, which is interpreted in the style of Font.decode. The usual format of the font string is


where both style and size are optional. If any of these parts are specified as an asterisk, the existing value is retained.

str - A String specifying the new font
