Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\*\shell\SublimeText3]
@="Edit with SublimeText3"
"Icon"="D:\\AppFiles\\SublimeText3\\sublime_text.exe,0"
[HKEY_CLASSES_ROOT\*\shell\SublimeText3\command]
@="D:\\AppFiles\\SublimeText3\\sublime_text.exe \"%1\""
[HKEY_CLASSES_ROOT\Directory\shell\SublimeText3]

1、 Java 8 date and local date

Java8 datetime API, add LocalDate, LocalDateTime, LocalTime and other thread-safe classes:
LocalDate: only the date, such as: 2019-07-13LocalTime: only the time, such as: 08:30LocalDateTime: date + time, such as: 2019-07-13 08:30
1. CONVERT DATE TO LOCALDATE

    public static LocalDate date2LocalDate(Date date) {
        if(null == date) {
            return null;
        }
        return date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
    }

2. CONVERT LOCALDATE TO DATE


    public static Date localDate2Date(LocalDate localDate) {
        if(null == localDate) {
            return null;
        }
        ZonedDateTime zonedDateTime = localDate.atStartOfDay(ZoneId.systemDefault());
        return Date.from(zonedDateTime.toInstant());
    }

2.LocalDateTime is converted to Date

    public static Date localDateTime2Date(LocalDateTime localDateTime) {
        return Date.from(localDateTime.atZone(ZoneId.systemDefault()).toInstant());
    }

3. LocalDate format

    public static String formatDate(Date date) {
        LocalDate localDate = date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
        return localDate.format(DateTimeFormatter.ofPattern("yyyy-MM-dd"));
    }
