十二、命令模式

public interface Command {
    void excute();
}

public class ReadCommand implements Command {
    @Override
    public void excute() {
        System.out.println("read something");
    }
}

public class WriteCommand implements Command {
    @Override
    public void excute() {
        System.out.println("write something");
    }
}

public class Application {
    public static void main(String[] args) {
        List<Command> commands = Lists.newArrayList(new ReadCommand(),
                                                    new WriteCommand());

        commands.forEach(Command::excute);
    }
}
