Correct the faults in the isLeapYear() and getNumDaysInMonth() methods of Figure 11-12 and generate test cases using the path testing methods. Are the test cases you found different than those of Table 11-14 and Figure 11-13? Why? Would the test cases you found uncover the faults you corrected?
What will be an ideal response?
```
public class MonthOutOfBounds extends Exception {...};
public class YearOutOfBounds extends Exception {...};
public class MyGregorianCalendar {
public static boolean isLeapYear(int year) {
boolean leap;
if ((year%400) == 0) {
leap = true;
} else if ((year%100) == 0) {
leap = false;
} else if ((year%4) == 0) {
leap = true;
} else {
leap = false;
}
return leap;
}
public static int getNumDaysInMonth(int month, int year)
throws MonthOutOfBounds, YearOutOfBounds {
int numDays;
if (year < 1) {
throw new YearOutOfBounds(year);
}
if (month == 1 || month == 3 || month == 5 || month == 7 ||
month == 10 || month == 12) {
numDays = 31;
} else if (month == 4 || month == 6 || month == 9 || month == 11) {
numDays = 30;
} else if (month == 2) {
if (isLeapYear(year)) {
numDays = 29;
} else {
numDays = 28;
}
} else {
throw new MonthOutOfBounds(month);
}
return numDays;
}
...
}
```
