loop example can be turned into 1 single statement too:
final int[] example = new int[10]; // 10 indexed integer values
void setup() {
//java.util.Arrays.fill(example, 0, 4, 999); // assign value 999 to indices 0 to 3
for (int i = 0; i < 4; example[i++] = 999); // assign value 999 to indices 0 to 3
println(example);
exit();
}
