My issue:

I don't know how to shift left after swapping arrays.

My code:

import java.util.Scanner;
public class StudentScores {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
final int SCORES_SIZE = 4;
int[] oldScores = new int[SCORES_SIZE];
int[] newScores = new int[SCORES_SIZE];
int i;

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

/* Your solution goes here */for (i=0; i < oldScores.length; i++) {
newScores[i]= oldScores[i];
}

// student code ends here

for (i = 0; i < newScores.length; ++i) {
System.out.print(newScores[i] + " ");
}
System.out.println();
}
}

CHALLENGE
7.7.2: Copy and modify array elements.
ACTIVITY
Write a loop that sets newScores to oldScores shifted once left, with element 0 copied to the
end. Ex: If oldScores = {10, 20, 30, 40}, then newScores = {20, 30, 40, 10}.
Note: These activities may test code with different test values. This activity will perform two
tests, both with a 4-element array (int oldScores[4]). See "How to Use zyBooks".
Also note: If the submitted code tries to access an invalid array element, such as newScores[9]
for a 4-element array, the test may generate strange results. Or the test may crash and report
"Program end never reached", in which case the system doesn't print the test case that caused
the reported message.
