Question
I NEED THE WHOLE PROGRAM!! NOT JUST THE MAIN PROGRAMMING!!! IN JAVA!!
Calculate a player’s batting statistics
Console
Operation
This application calculates the batting average and slugging percentage for one or more baseball or softball players.
For each player, the application first asks for the number of at bats. Then, for each at bat, the application asks for the result.
To enter an at-bat result, the user enters the number of bases earned by the batter. If the batter was out, the user enters 0. Otherwise, the user enters 1 for a single, 2 for a double, 3 for a triple, or 4 for a home run.
After all the at-bat results are entered, the application displays the batting average and slugging percent.
Specifications
The batting average is the total number of at bats for which the player earned at least one base divided by the number of at bats.
The slugging percentage is the total number of bases earned divided by the number of at bats.
Use an array to store the at-bat results for a player.
Validate the input so the user can enter only positive integers. For the at-bat results, the user’s entry must be 0, 1, 2, 3, or 4.
Validate the user’s response to the question “Another batter?” so the user can enter only Y, y, N, or n. If the user enters Y or y, calculate the statistics for another batter. Otherwise, end the program.
Format the batting average and slugging percent to show three decimal digits.
Enhancements
At the start of the program, prompt the user for the number of batters to enter. Then, save the statistics for all of the batters in a two-dimensional array. The program won’t have to ask the user whether to enter data for another batter, since it will know how many batters are to be entered. After all batters have been entered, print a one-line summary for each batter:
Instead of storing an array of integers, create a class named AtBat and store instances of this class in the array. This class should define an enumeration named Result with members OUT, SINGLE, DOUBLE, TRIPLE, and HOMERUN. The class should have a constructor that accepts a Result parameter and a method named basesEarned that returns an int representing the number of bases earned for the at bat.
