Testing the robot builder in Java

Generation Code 128B in Java Testing the robot builder

The test harness, TestRobotBuilderjava, acts as the client code That code lets the user decide what type of robot to build with the following prompt: Do you want a cookie robot [c] or an automotive one [a]

import javaio*; public class TestRobotBuilder { public static void main(String args[]) { String response = a ; Systemoutprint( Do you want a cookie robot [c] or an automotive one [a] ); BufferedReader reader = new BufferedReader(new InputStreamReader(Systemin)); try{ response = readerreadLine(); } catch (IOException e){ Systemerrprintln( Error ); } }

Depending on which type of robot the user selects, a cookie robot builder or an automotive robot builder is created and stored in the RobotBuilder variable builder (Note that the rest of the code is independent of the type of builder and robot you re using)

import javaio*; public class TestRobotBuilder { public static void main(String args[]) { RobotBuilder builder; String response = a ; Systemoutprint( Do you want a cookie robot [c] or an automotive one [a] ); BufferedReader reader = new BufferedReader(new InputStreamReader(Systemin)); try{ response = readerreadLine(); } catch (IOException e){ Systemerrprintln( Error ); } if (responseequals( c )){ builder = new CookieRobotBuilder(); } else { builder = new AutomotiveRobotBuilder(); } } }

Then this client code can construct the robot as it wants, using the builder s addStart, addGetParts, addAssemble, addTest, and addStop methods, which it can use in any order

import javaio*; public class TestRobotBuilder { public static void main(String args[]) { RobotBuilder builder; String response = a ; Systemoutprint( Do you want a cookie robot [c] or an automotive one [a] ); BufferedReader reader = new BufferedReader(new InputStreamReader(Systemin));

try{ response = readerreadLine(); } catch (IOException e){ Systemerrprintln( Error ); } if (responseequals( c )){ builder = new CookieRobotBuilder(); } else { builder = new AutomotiveRobotBuilder(); } //Start the construction process builderaddStart(); builderaddTest(); builderaddAssemble(); builderaddStop(); } }

After the robot has been built, the client code calls the builder s getRobot method, which returns a robot stored in a RobotBuildable variable And you can call the robot s go method to make sure it does what it s supposed to

import javaio*; public class TestRobotBuilder { public static void main(String args[]) { RobotBuilder builder; RobotBuildable robot; String response = a ; Systemoutprint( Do you want a cookie robot [c] or an automotive one [a] ); BufferedReader reader = new BufferedReader(new InputStreamReader(Systemin)); try{ response = readerreadLine(); } catch (IOException e){ Systemerrprintln( Error ); }

if (responseequals( c )){ builder = new CookieRobotBuilder(); } else { builder = new AutomotiveRobotBuilder(); } //Start the construction process builderaddStart(); builderaddTest(); builderaddAssemble(); builderaddStop(); robot = buildergetRobot(); robotgo(); } }

This client code can produce cookie robots or automotive robots simply by selecting the right builder Here, it is creating a cookie robot:

Do you want a cookie robot [c] or an automotive one [a] c Starting Crunching a cookie Baking a cookie Stopping

And here it is creating an automotive robot, using the same construction sequence:

Do you want a cookie robot [c] or an automotive one [a] a Starting Revving the engine Installing the carburetor Stopping
