Why LocalDateTime?

• Basically, the Date object is a [redacted] to use so they made it better.
• For documentation purposes, the main reason for choosing the Java 8 Date/Time API is it's Ease of use and Ease of Understanding over the previous Date object.

Examples of Use:

LocalDate localDate = LocalDate.now();
LocalDate.of(2015, 02, 20);
LocalDate.parse("2015-02-20");

LocalDate tomorrow = LocalDate.now().plusDays(1);
localDateTime.minusHours(2);
DayOfWeek sunday = LocalDate.parse("2016-06-12").getDayOfWeek();
boolean leapYear = LocalDate.now().isLeapYear();

localDateTime.format(DateTimeFormatter.ofPattern("yyyy/MM/dd"));
String localDateString = localDateTime.format(DateTimeFormatter.ISO_DATE);

How to use Firestore

Steps to connect to Firestore and query the tables:

1. Add the following line of code as an attribute for the class:

   FirebaseFirestore db = FirebaseFirestore.getInstance();

   Also need to add import statement for Firestore

   import com.google.firebase.firestore.FirebaseFirestore;

2. (Optional) If we are referencing the same collection can add the following:

   final CollectionReference collectionReference = db.collection(collectionName);
