我遇到了嘗試查找Eclipse的Julian日期的測試問題。測試中的(每月)高亮紅色。任何人都可以幫忙嗎?非常感激。在Java Eclipse中測試Julian日期
public static boolean validDate (int day, int month, int year){
if(month >=1 && month<=12 && day>=1 && day <=31) {
if (day>30) {
return false;
}
}
if(month==2){
if (leapYear(year)!= true&&day>28){
return false;
}
}
return true;
}
//Array to store total days in month, not leap year
public static int julianDate(int day, int month, int year){
int m[] = {31,28,31,30,31,30,31,31,30,31,30,31};
int total = 0; // to store total days
// loop to add the number of days in each month, previous to the month chosen
for(int i = 0; i < month - 1; i++){
total = total + m[i]; //adding value in array at index position i to total variable
}
// checking if the month entered is after feb and also leap year
if(month > 2 && leapYear(year)){
//total holds days in previous months and adds days in current month - plus 1 as it is condition of leapyear
return total + day + 1;
}else{
// no added 1 as the else is not leap year
return total + day;
}
}
測試
else if (menuNumber == 2);
System.out.println("Enter Julain Date DD/MM/YYYY"); //Here he print out Julain Date and asks for specific format dd/mm/yyyy
int day, month, year = in.nextInt();
System.out.println();
if (newDate.validDate(day, month, year)) {
System.out.println(newDate.validDate(day, month, year));
}else{
System.out.println("Not a Date");
}
你有沒有考慮過使用[JodaTime](http://www.joda.org/joda-time/)? – GGrec
我沒有,因爲我不知道如何使用它,也需要做到這一點具體方式 –
