What is the output of the following code?
String printDate = LocalDate.parse("2057-08-11")
.format(DateTimeFormatter.ISO_DATE_TIME);
System.out.println(printDate);
e
The example code in this question calls LocalDate.
parse(), passing it a string value but no DateTimeFormatter instance.
In this case, the text 2057-08-11 is parsed using DateTimeFormatter.ISO_LOCAL_DATE.
LocalDate.parse() returns a LocalDate instance.
The example code then calls the format method on a LocalDate instance, using DateTimeFormatter.ISO_DATE_TIME.
The code compiles successfully because the format method accepts a DateTimeFormatter instance.
But format() throws an exception at runtime because it tries to format a LocalDate instance using a formatter (ISO_DATE_TIME) that defines rules for a date/time object.
When no matching time values are found in a LocalDate object, an exception is thrown.
