Java: format date string "150520" into "May 20, 2015"

Question

I'm using Java 8 on linux with the following code

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyMMDD",Locale.ENGLISH);
LocalDate exampleDate  = LocalDate.parse(myDate, formatter);

where myDate is a String equal to "150520". I'm getting error:

java.time.format.DateTimeParseException: Text '150520' could not 
be parsed: Conflict found: Field MonthOfYear 1 differs from 
MonthOfYear 5 derived from 2015-01-20

I'd like to return May 20, 2015 for example. Any idea what's wrong?

UPDATE

Replacing the date code D with d eliminates this error. How to format into readable date?

You want yyMMdd. The uppercase D parses "day of year" not "day of month".

[Edit] for the printing part, you could do DateTimeFormatter.ofPattern("MMM dd, yyyy").format(theDate).

Change

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyMMDD",Locale.ENGLISH);

with

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyMMdd",Locale.ENGLISH);

You need to use this format string "yyMMdd". According to the docs

Symbol  Meaning                     Presentation      Examples
------  -------                     ------------      -------
D       day-of-year                 number            189
d       day-of-month                number            10

Java: format date string "150520" into "May 20, 2015"
