与えられた：
public class Counter {
public static void main (String[ ] args) {
int a = 10;
int b = -1;
assert (b >=1) : "Invalid Denominator";
int = a / b;
System.out.println (c);
}
}
-eaオプションを使用してコードを実行した結果はどうなりますか？

Given the code fragment:
ZonedDateTime depart = ZonedDateTime.of(2015, 1, 15, 3, 0, 0, 0,
ZoneID.of("UTC-7"));
ZonedDateTime arrive = ZonedDateTime.of(2015, 1, 15, 9, 0, 0, 0,
ZoneID.of("UTC-5"));
long hrs = ChronoUnit.HOURS.between(depart, arrive); //line n1
System.out.println("Travel time is" + hrs + "hours");
