Java Basic(36)-Time Class

public class tuna {

private int hour;

private int minute;

private int second;

public void setTime(int h, int m, int s){

hour = ((h>=0 && h<24) ? h:0); 如果h是> =或<24，把這個數字放在h

minute = ((m>=0 && m<60) ? M:0); 如果不是那麼h = 0;

second = ((s>=0 && s<60) ? s:0);

}

public String toMilitary(){

return String.format("%02d:%02d:%02d:", hour,minute,second );

}

}

%02d:%02d:%02d: →意味著每個整數要兩個小數點，它們之間加入冒號

hour,minute,second →你想放什麼變量

class apples{

public static void main(String args[]){

tuna tunaObject = new tuna();

System.out.println(tunaObject.toMilitary());

tunaObject.setTime(13, 27, 6);

System.out.println(tunaObject.toMilitary());

}

}

該Program將運行這樣的：

00:00:00

13:27:06
