Question
DRA Overview In Lab 6 you created an object oriented version of your DoubleDrat game. In this lab, you will rewrite your application using : file input/output, ArrayList, and inheritance. You will add code to your game to allow the user to choose from two games: DoubleDrat or TripleDrat Pre-Lab [5 points] Create the GameLauncher following the provided instructions and bring it to your lab session NOTES Each program should include comments that explain what each block of code is doing. Additionally, the programs should compile without errors, and run with the results described in the exercise. The following deductions will be made from each exercise if any of the following is incorrect or missing Lab (90 Points) Create the DoubleDrat and TripleDrat games using the design provided on the following pages. Your output should match the format shown on the last page, although your actual output will vary based on the the outcome of the game Proper formatting [5 points] Proper names for classes and variables [5 points Comments [5 points per class] Program doesn't compile[ 10 points] Source code (java file) missing [10 points] Executable (class file) missing [10 points] Missing array where an array was required [5 points each] Missing loop where a loop was required [5 points each] Missing class from the design provided [10 points each] Missing method from the design provided [ 5 points each] Submit the ava and class files via Canvas (as a single zip- file). Include a comment block at the top of each Java file that includes your name, student id number, and "Lab 6- Spring 2018". Also be sure to include the answers to the post-lab questions found in these instructionsExplanation / Answer
