java题答案3、设计Time类，具有日期和时间处理的功能：（1） incrementHour()方法，增加1小时；（2

public static Time incrementHour(Time time) {
if (time == null) {
return time;
}
time.setHours(time.getHours() + 1);
return time;
}
public static Time incrementMinute(Time time) {
if (time == null) {
return time;
}
time.setMinutes(time.getMinutes() + 1);
return time;
}
public static Time tick(Time time) {
if (time == null) {
return time;
}
time.setSeconds(time.getSeconds() + 1);
return time;
}
public static void main(String[] args) {
Time time = new Time(1, 1, 1);
Time aTime = incrementHour(time);
System.out.println(aTime.toString());
Time bTime = incrementMinute(time);
System.out.println(bTime.toString());
Time cTime = tick(time);
System.out.println(cTime.toString());
}
