Description

Interface Summary

Directions	This interface is a bare wrapper for Bergin's Directions interface.
RobotTask	This class defines the common interface for all robot task objects.

Class Summary

Browser	This class provides a simple interface to your web browser.
IOHelper	This class provides several static methods that streamline the use of basic I/O operations in Java.
MazeGenerator	The class generates mazes for Karel J.
Robot	This class is a simple wrapper for Bergin's Robot.
RunRobotTask	This class represents a main program that takes a command-line argument that names a RobotTask; it creates an instance of the named task and then runs it.
TestableRobot	This class extends Robot with assertion capabilities, adding a number of methods useful in writing test cases and in using test-driven development.
TestableWorld	This class provides the basic assertion capabilities for Karel's World in the form of methods useful for writing test cases.
ur_Robot	This class is a simple wrapper for Bergin's ur_Robot class and represents a minimal robot.
Version	This class allows access to the package version information.
VPIRobot	A class that represents a robot.
World	This class can be used to build and maintain the world in which robots work and play.

Package cs1705 Description

This package provides all of the course-specific classes written especially for CS 1705: Introduction to Object-Oriented Development I.

There are one interface and two main classes in this package that students use directly:

• RobotTask: a base interface for all robot "tasks" providing one method signature: void task(). Most main robot programs consist of a specialized class implementing this interface.

• VPIRobot: the base class for all of your robots. It is a lot like the ur_Robot discussed in Bergin's book, but also adds a number of testing capabilities and a default constructor (you can create one without giving any parameters, if you like).

• World: this is the class for accessing the robot's world. It is similar in many respects to Bergin's World class, but it is possible to get an instance of this world as an object on the object bench in BlueJ, and then call testing-oriented methods on it directly.

For those of you who are adventurous, there is a world builder that you can use to directly edit Karel world description files. It only works on files stored on the local disk, not on URLs, of course. You can invoke it from a command line window:

java -cp C:/BlueJ/lib/cs1705.jar kareltherobot.WorldBuilder

If you are working on your own machine, you can create a shortcut for this purpose.
