Constructor Detail

public ConsoleProgram()

Creates a new console program.

Usage:

ConsoleProgram program = new ConsoleProgram();

Method Detail

public void run()

Contains the code to be executed for each specific program subclass. If you are defining your own ConsoleProgram class, you need to override the definition of run so that it contains the code for your application.

public void setFont(Font font)

Sets the font for the console.

Usage:

program.setFont(font);

Parameter:

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

Usage:

program.setFont(str);

Parameter:

str	A String specifying the new font
