I've already used if statements previously in this course, it's pretty unavoidable, but now I'll go into the details of the if keyword, and it's associated keyword, else. To demonstrate this, I'll start with an integer variable that I'll name monthNumber, and I'll give it a value of zero. Now, when you're working with date and time values in Java, traditionally monthNumbers are indexed starting at zero. So, zero means January, one is February, and so on. There's a newer package that was introduced in Java 8 that changes this to indexing starting with one, but you can't use it everywhere you're programming Java. For example, if you're coding in Java for Android, you might still have to use the older approach. So, I'm going to assume I'm using the older libraries. MonthNumber zero means it's January.
