Question

In the sport of diving, seven judges award a score between 0 and 10, where each score may be a floating-point value. The highest and lowest scores are thrown out and the remaining scores are added together. The sum is then multiplied by the degree of difficulty for that dive. The degree of difficulty ranges from 1.2 to 3.8 points. The total is then multiplied by 0.6 to determine the diver's score. Write a computer program that inputs a degree of difficulty and seven judges' scores, and outputs the overall score for that dive. The program should ensure that allinputs are within the allowable data ranges. You will need to use an array to hold the seven judges' scores and use the sorting alogrithm to determine the highest and the lowest scores.

Answer 1

Answer:

1. import java.util.Scanner;
2. import java.util.Arrays;
4. public class Main {
6.    public static void main(String[] args)
7.    {
8.        double scores[] = new double[7];
9.        double difficulty;
10.        double sum = 0;
11.        double overallScore;
13.        Scanner input = new Scanner(System.in);
15.        for(int i=0; i < 7; i++){
16.            do{
17.                System.out.print("Input score: ");
18.                scores[i] = input.nextDouble();
19.            }while( scores[i] < 0 || scores[i]  > 10);
20.        }
22.        do{
23.            System.out.print("Input a degree of difficulty: ");
24.            difficulty = input.nextDouble();
25.        }while(difficulty <1.2 || difficulty >3.8);
27.        Arrays.sort(scores);
28.        for(int i=1; i < scores.length -1; i++){
29.            sum += scores[i];
30.        }
32.        overallScore = (sum * difficulty) * 0.6;
33.        System.out.println("The diver score is " + overallScore);
34.    }
35. }

Explanation:

The solution code is written in Java.

Firstly declare all the necessary variables to hold the scores from 7 judges, degree of difficulty, sum and overall score (Line 8-11)

Create a for loop that run for 7 iterations to get user input for score (Line 15-20). A do while loop is included to set the condition that the input score must be between 0 to 10 in order to proceed to the next input.

Next, get the user input for the degree of difficulty (Line 22-25). Here the do while loop is used again to ensure the input of difficulty must be 1.2-3.8.

Next, use the Java Arrays sort method to sort the scores array in ascending order (Line 27).

Sum up the scores of the array (Line 28-30) and apply the formula as given in the question to calculate the overall score (Line 32). Display the overall score to terminal (Line 33).
