For this assignment, you will work with and extend a class that keeps score for a basketball team. The HoopsScorer class has methods for adding points to a team's score and accessing that score.

In-class exercises - may be completed with a partner

• Download the HoopsScorer class and add it to a BlueJ project. Create a HoopsScorer object and test the recordMadeShot and getScore methods.
  
  
• Consider the following questions about this class and discuss your answers with your partner:
  • Are there limits to the range of numbers that the recordMadeShot method will take as input? Can you enter a number greater than three? Can you enter zero or a negative number? How are these inputs handled by the method?
  • What happens if you enter a non-integer input for recordMadeShot, such as 1.5 or "foo"?
  
  
• Modify the recordMadeShot method so that it checks to make sure that the number of points must be an integer between 1 and 3. Do so by replacing the one statement inside the method with the following if-else statement:

      if (numPoints >= 1 && numPoints <= 3) {
          this.score += numPoints;
      }
      else {
          System.out.println("Illegal number of points.");
      }
  

  Test your modified function to make sure that it disregards illegal point values.
  
  
• Currently, there is no way to reset the score. Add the following method to the class. Be careful that you add the method inside the class (before the final right-brace), but not inside another method.

      /**
       * Resets the score.
       */
      public void reset() {
          this.score = 0;
      }
  

  Test your new method to make sure it behaves as it should.
  
  
• You may note that the constructor and the reset method now contain the same code (a single assignment statement). That is because starting and resetting a HoopsScorer are essentially the same task - setting the score field to zero. While having two methods that do the same thing is perfectly legal, it is also redundant (and redundancy in code is generally bad). Modify the constructor so that, instead of initializing the field itself, it calls the reset method to perform the task. That is, replace the assignment statement in the constructor with the method call:

   
          this.reset();
  

• Once you have fully tested your class, you can download the ScoreBoard class and add it to your BlueJ project. This class defines a graphical user interface (GUI) that allows you to select a made shot at the click of a button, and then see the score updated. Once you have compiled this class, create an object of type ScoreBoard and call its showBoard method to show the score board GUI. Note that the ScoreBoard actually creates two HoopsScorer objects, one for the home team and one for the visiting team.

Homework assignment - must be completed individually

• Since you will want to keep track of the shooting percentages for the different types of shots (3-point field goal, 2-point field goal, and 1-point free throw), you will need to add additional fields that keep track of makes and misses for each shot type. Each field must be initialized in the reset method (and thus indirectly initialized by the constructor). You will also need to modify the recordMadeShot method so that the new fields are updated appropriately. Be sure to test your additions/modifications thoroughly before moving on to the next step.
  
  
• You will need to add a recordMissedShot method that looks similar to the existing recordMadeShot method, in that it will have a parameter that specifies which type of shot was missed. When called, it will update the appropriate field(s) so that a missed shot of that type is recorded.
  
  
• You will need to add a getPercentage method that similarly has a parameter specifying the type of shot. The method should calculate and return the shooting percentage (100.0*madeShots/totalShots) for that type of shot, rounded to the nearest integer. For example, if a team took 6 3-point shots and made only 2 of them, then a call to getPercentage with input 3 should return 33. If a team has not taken any shots of a specific type, the shooting percentage should be reported as 0.

  Hint: To round a number to the nearest integer, you will want to make use of the built-in Math.round method. This method takes a single number as input and returns the whole number closest to that number. Oddly enough, it returns it as a double, so the call Math.round(33.3) will actually return 33.0. To cast that into a value of type int, place "(int)" in front of the call. For example, (int)Math.round(33.3) will return the int value 33.

• You will also need to add a method named getFGPercentage that has no parameters. This method should return the combined shooting percentage of all field goals (2- and 3-pointers), again rounded to the nearest integer. For example, if a team made 4 of 6 2-pointers and 1 of 4 3-pointers, their overall field goal percentage should be reported as 50.

Once you have tested methods, download the StatBoard GUI class that makes use of the extended functionality of HoopsScorer to display shooting percentages as well as scores.
