A DESCRIPTION OF THE PROBLEM :
The description for the DateTimeFormatter provides two Java snippets which have several issues. 

These are those two examples:

First example:

  String text = date.toString(formatter);
  LocalDate date = LocalDate.parse(text, formatter);

Second example:

  DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
  String text = date.toString(formatter);
  LocalDate date = LocalDate.parse(text, formatter);

The Issues:
[1] There is no need to provide both examples in the description; the second is sufficient.
[2] Both examples are invalid Java.
[3] Both examples reference a variable name "date" before it is declared.
[4] Both examples pass method "toString()" a "DateTimeFormatter" argument, but no such method exists in the JDK. Presumably the calls should be to method format() rather than toString().







EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A clearer and valid example for the DateTimeFormatter documentation might be:

            LocalDate date1 = LocalDate.of(2014, 10, 25);
            System.out.println("date1: " + date1.toString());
            DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
            String text = date1.format(formatter);
            LocalDate date2 = LocalDate.parse(text, formatter);
            System.out.println("date2: " + date2.toString());

ACTUAL -
The following erroneous text appears in the DateTimeFormatter documentation:

  String text = date.toString(formatter);
  LocalDate date = LocalDate.parse(text, formatter);

.....

  DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
  String text = date.toString(formatter);
  LocalDate date = LocalDate.parse(text, formatter);
