Answer Thanks to JuanZe's comment, I found the magic, it is also. This parsing operation uses the to produce a Date. Resolving separate fields to form a complete date and time is a complex process with behaviour distributed across a number of classes. Four of these perform both the parse and resolve phases. The builder allows a format pattern to be built up step by step, consisting of literal, text, numeric, pattern and localized elements in any order.

When parsing dates, the Java SimpleDateFormat typically parses the date from a. In implementation terms, this method behaves as follows. Parsing Strings into Dates The SimpleDateFormat class has some additional methods, notably parse , which tries to parse a string according to the format stored in the given SimpleDateFormat object. In other words, the alphabetical order is the same as the date-time order. The chronology of the result is either the chronology that was parsed, or if no chronology was parsed, it is the chronology set on this class, or if that is null, it is IsoChronology.

The date is defined in the same manner as was used for the previous parsing example, but this pattern also includes the hour, minutes, and a. I then use these same formatters to parse the String values back to Dates. If you're as astonished as I was, see. Returns a negative value if the invoking object is earlier than date. It outputs 'Z' if the offset is zero.

Text: If the number of pattern letters is 4 or more, the full form is used; otherwise a short or abbreviated form is used if available. The output will be '+0000' when the offset is zero. The locale can be controlled using on the result of this method. On output: the offsets of the alignment field. The pattern is just a regular.

It uses a builder to construct the date time with time zone step-by-step. Number: If the count of letters is one, then the value is output using the minimum number of digits and without padding. If the count of letters is one, two or three, then the short name is output. This returns a formatter with similar state to this formatter but with the resolver style set.

For default format, it is simply converted from a LocalDateTime object to a string internally using a toString method. Its month is a base-1 number, which means that January is equal to 1 instead of 0, so you can use the digit instead of the static Java field. In case of error, returns null. Returns 0 if the values are equal. For most Java developers, Android is not exactly Java. If you're interested, here's a list of all. How can I obtain a instance from the given string?
