Strategy 1

Skills:

• Make an instance variable.
• Define an interface.
• Implement an interface.
• Write a constructor given some information.

Questions:

1. The class MLM is a Strategy that moves forward, puts down a beeper, turns left, and moves forward again. Write the class MLM.

2. Write the class XBot, which is a class of robot that only moves horizontally.

   • Starts at street=n, avenue=3 facing East
   • turnLeft really turns the robot to face in the opposite direction of the original direction

3. Create a new interface NamedStrategy which adds a String stratName() method to the abilities of a Strategy. The stratName() method should return the strategy’s name.

4. Make a class LaySpeak which implements NamedStrategy. The doIt method both puts down two beepers and prints out the name of the strategy.

    System.out.println(name of strategy);
   

   This kind of strategy should learn its name when it is constructed.
