Modify TestScoreAppMath as described below complete solution correct answer key 1. Use the += operator to increase the scoreCount and scoreTotal variables. Then test this to makes sure it works. 2. As the user enters test scores, use the methods of the Math class to keep track of the minimum and maximum scores. When the user enter 999 to end the program, display these scores at the end of the other output data. Now, test these changes to make sure that they work. 3. Change the variable that you use to total the scores from a double to an int data type. Then use casting to cast the score count and score total to doubles as you calculate the average score and save that average as a double. Now, test that change. 4. Use the NumberFormat class to round the average score to one decimal place before displaying it at the end of the program. Then, test this change. Note that the rounding method that’s used doesn’t matter in a program like this.
