First part

For this first part, start with the code in Listing 7.5, page 265 (see below), but don\'t use the method printMax (that won\'t help you with the assignment requirement.)
Create a program that reads game scores, and then assigns these scores into the leaderboard (if they make it into the leaderboard): \"First place\" if score is best, then \"Second,\" \"Third,\" and so on. The program prompts the user to enter the total number of gamers, then prompts the user to enter all of the scores, and concludes by displaying the grades. Here is a sample (DO NOT USE THE SAME SCORES) run:
Enter the number of scores you\'d like to enter: 4
Then enter four scores: 40 55 70 58
Gamer 0 score is 40 and grade is \"Fourth.\"
Gamer 1 score is 55 and grade is \"Third.\"
Gamer 2 score is 70 and grade is \"First.\"
Gamer 3 score is 58 and grade is \"Second\".

LISTING 7.5 VarArgsDemo.java

1 public class VarArgsDemo {

2 public static void main(String[] args) {

3 printMax(34, 3, 3, 2, 56.5);

4 printMax(new double[]{1, 2, 3});

5 }

7 public static void printMax(double... numbers) {

8 if (numbers.length == 0) {

9 System.out.println(\"No argument passed\");

10 return;

11 }

12

13 double result = numbers[0];

14

15 for (int i = 1; i < numbers.length; i++)

16 if (numbers[i] > result)

17 result = numbers[i];

18

19 System.out.println(\"The max value is \" + result);

20 }

21 }
