Hands-On Design Patterns with Java

Driver

The Driver class is created to test the functionality of the state design pattern implementation:

public class Driver {    public static void main(String[] args) {        PrinterOffLine initialPrinterState = new PrinterOffLine();        Printer printer = new Printer(initialPrinterState);        System.out.println("\n");        printer.pushPrint();        printer.pushPrint();        printer.pushPrint();        System.out.println("\n\n");    }}

The Driver class contains a main() method that drives the application's execution.
