Example 6-1 contains some examples of converting in both directions between strings and
dates.

Example 6-1. DateFormatter.java—Example date formatting and parsing
public public class class DateFormatter DateFormatter {

public public static static void void main ( String [] args ) {

// Format a date ISO8601-like but with slashes instead of dashes
DateTimeFormatter df = DateTimeFormatter . ofPattern ( "yyyy/LL/dd" );
System . out . println ( df . format ( LocalDate . now ()));

// Parse a String to a date using the same formatter
System . out . println ( LocalDate . parse ( "2014/04/01" , df ));
