Unit 6: Arrays

int[] scores = {95, 87, 73, 91, 88};
//    index:    0   1   2   3   4

System.out.println(scores[0]);     // 95 (first element)
System.out.println(scores[4]);     // 88 (last element)
System.out.println(scores.length); // 5 (number of elements)

// Standard for loop — when you need the index
for (int i = 0; i < arr.length; i++) {
    System.out.println(arr[i]);
}

// Enhanced for loop — when you just need each value
for (int value : arr) {
    System.out.println(value);
}
