Question

Please complete in Java. Thanks in advance! Also, please note the solution in bold text. Thanks!

Array testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.

import java.util.Scanner;

public class SumOfExcess {
   public static void main (String [] args) {
      Scanner scnr = new Scanner(System.in);
      final int NUM_VALS = 4;
      int[] testGrades = new int[NUM_VALS];
      int i;
      int sumExtra = -9999; // Assign sumExtra with 0 before your for loop

      for (i = 0; i < testGrades.length; ++i) {
         testGrades[i] = scnr.nextInt();
      }

      /* Your solution goes here */

      System.out.println("sumExtra: " + sumExtra);
   }
}

import java.util.Scanner;

public class SumOfExcess {
    public static void main (String [] args) {
        Scanner scnr = new Scanner(System.in);
        final int NUM_VALS = 4;
        int[] testGrades = new int[NUM_VALS];
        int i;
        int sumExtra = -9999; // Assign sumExtra with 0 before your for loop

        for (i = 0; i < testGrades.length; ++i) {
            testGrades[i] = scnr.nextInt();
        }

        sumExtra = 0;
        for (i = 0; i < testGrades.length; ++i) {
            if(testGrades[i]>100){
                sumExtra += (testGrades[i]-100);
            }
        }

        System.out.println("sumExtra: " + sumExtra);
    }
}
