With the updated Python function, comes an updated Java function, the code now looks like this, similar to the Python function there are two new checks and a final check that daysInMonth is not still zero: With this function working correctly, I can now continue with developing the GUI.

I have just realised a mistake in my validDate Function. The mistake is that it only validates the day and not the month or year, i also realised that it would validate the day even if the day is zero so I need to fix this. It was only when I was creating the Java …

Something I am constantly wanting to do in a lot of programs is see if a value is in an array. For another function which I wish to write to add to the Zeller program this will come in handy. The basic algorithm looks like this: SET value TO RequiredValueSET array TO ArrayToSearchSET isIn TO …

Factoral and Recursion
We all remember factorals from school but to remind us what they are, a factoral is the product of all the positive integers less than or equal to the initial number(n): For example: Strangely 0!=1 there is a mathematical proof which states why but I will not be expanding on it here, I will however …
