Please help decribe the below code where solve(grade) is int array

Question

int[] result = solve(grades);
for (int i = 0; i < result.length; i++) {
           System.out.print(result[i] + (i != result.length - 1 ? "\n" : ""));
}

Answer 1

If i is for the last array entry, concatenate a new line "\n" to the string. For every other array entry, concatenate a empty string.

(condition ? trueResult : falseResult) if the condition is true, this expression returns the trueResult value. Otherwise, the falseResult value is returned.
