15-100 PRACTICE ONLINE PROGRAMMING TEST 1

Problem Statement

In the dice game Strike Out, the goal is to win 200 points before rolling the strike-out sum three times.

• The player enters a number between 1 and 6 (inclusive). This number is added to a random roll of one die to establish the strike-out sum.

• The player starts with 0 points.

• The player rolls two standard 6-sided die and scores as follows.

  • If the player rolls "doubles" (the same number on both die), then the player receives 10 times the number rolled. For example if the player rolls two 4s, the player wins 40 points.

  • Otherwise, if the players rolls two different numbers the player receives an amount equal to the product shown on the two die. For example, if the player rolls a 2 and 5, the player receives 10 points.

  • If the sum of the two dice the player rolls equals the strike-out sum, the player earns one strike and no points are added.

• The player continues rolling until the player reaches at least 200 points (win) or earns three strikes (lose). At the end of the game, report whether the player wins or loses.

Programming Requirement

• Using Eclipse, write the main method to play this game in the Java class StrikeOutGame provided to you in the downloaded project.

• To simulate the die you will create two Die objects using the Die class included in your programming project. Do not change or add any code in thee Die class. The Die class has the following methods you can use:

  public Die() Creates a standard six-side die.

  public int roll() Rolls the die and returns the number of spots on the face of the die.

• When you ask the user for a number between 1 and 6, if the user types a number outside that range, you should output Error: Bad input and ask the user to enter another number, until the input is valid. You may assume that the user always enters an integer.

• Include a static method displaySummary that has two parameters, the number of point and the number of strikes the player has so far. The method should not return anything. It simply displays the parameter data as follows:

  ******************************
  Strikes: 1
  Your total points: 35
  ******************************
  

• You do not need to provide any other helper methods, although you may do so if you wish.

  You should use names for your variables that are self-documenting (i.e. its name explains what the variable stores like "score" rather than "i") and indent your code using proper Java style. Include additional comments if you feel you need to explain your code.

  Program Testing

  Once you complete the StrikeOutGame class and run your program, use the following sample runs to test your program initially. Your program should match these following output exactly (for rolls given). The rolls you get may be different.
