我實際上正在嘗試創建一個鬧鐘，但我對如何編寫此方法有些困惑，這是迄今為止的方向和內容。/*** Formats the time one of the following ways:* "It is the top-of-the-hour" (if the minutes is 0)* "It is half-past the hour" (if the minutes is 30)* "It is 23 minutes past the hour" (if the minutes is more than 0 and less than 30; use the correct number* of minutes here (23 is just an example)* "It is 10 minutes before the hour" (if the minutes is more than 30 and less than 60; use the correct number* of minutes here (10 is just an example)** @precondition clock != null* @postcondition none** @param clock the clock to format* @return a string as described above*/public String formatMinutesInConversationalTone(AlarmClock clock) { if (clock == null) { throw new IllegalArgumentException("clock cannot be null"); } if (clock.getMinutes() == 0) { return "It is the top-of-the-hour"; } if(clock.getMinutes() == 30) { return "it is half past the hour"; } if(clock.getMinutes() > 0 && clock.getMinutes() < 30) { }}

我會對小時之前和之后的分鐘使用不同的條件，并用于String.format創建這些字符串：
public String formatMinutesInConversationalTone(AlarmClock clock) {
if (clock == null) {
throw new IllegalArgumentException("clock cannot be null");
}
int minutes = clock.getMinutes();
if (minutes == 0) {
return "It is the top-of-the-hour";
}
if (minutes == 30) {
return "It is half past the hour";
}
if (minutes < 30) {
return String.format("It is %d minutes past the hour", minutes);
}
return String.format("It is %d minutes before the hour", (60 - minutes));
}
