CHALLENGE
5.7.3: Modify array elements using other elements.
АCTVITY
Write a loop that sets each array element to the sum of itself and the next element, except for the last element which stays
the same. Be careful not to index beyond the last element. Ex:
Initial scores:
10, 20, 30, 40
Scores after the loop: 30, 50, 70, 40
The first element is 30 or 10 + 20, the second element is 50 or 20 + 30, and the third element is 70 or 30 + 40. The last
element remains the same.
import java.util.Scanner;
public class StudentScores {
public static void main (String [] args) {
new Scanner (System.in);
Scanner scnr
final int SCORES_SIZE
4;
%3!
int [] bonusScores =
new int [SCORES_SIZE];
int i;
for (i = 0; i < bonusScores.length; ++i) {
bonusScores[i]
= scnr.nextInt ();
/* Your solution goes here
*/
for (i = 0; i < bonusScores.length; ++i) {
System.out.print (bonus Scores[i] + " ");
System.out.println ();
}
}
Challenge 3: Scores.java and TestScores.java
Implement a Scores class. The class constructor should accept an array of scores as its argument. The class should have a method that returns the average of the scores. If any score in the array is negative or greater than 100, the class should throw an IllegalArgumentException.
Implement a TestScores class that creates an array and fills it with numbers given by the user. It should catch the exception thrown when the user enters an illegal value.
Checkpoint 1: Create an array and initialize all the elements to 0. Write a loop that will display
cach elements position and value. That is show "my_arrayf3] = 0" for each element as output
where 3 is the 4th clement in the array and 0 is value of that element. Now assign random values
to cach element. You can use the function rand() which will return an integer. This function will
return a number between 0 and RAND MAX = 32767. You can mod the value retumed by
rand() by 16 to fit the range 0 to 15. For debugging, the seed is the same until you change it.
This means all the output numbers will be the same as in the sample output.
Checkpoint 2: We want to calculate some base statistics for the array. You can access each
element of the array by using "my array[i]" where i is the index of the array. You may use a
loop to run through each index to cover the entire array. We will start finding statistics for this
array by finding the maximum value, minimum value, and sum of all values in…
