java.util.Date.from(localDate.atStartOfDay().atZone(ZoneId.systemDefault()).toInstant());

public static Date convertToTimeZone(Date date, String tzFrom, String tzTo) {
    return Date.from(LocalDateTime.ofInstant(date.toInstant(), ZoneId.of(tzTo)).atZone(ZoneId.of(tzFrom)).toInstant());
} 

简单的

public Date convertFrom(LocalDate date) {
    return java.sql.Timestamp.valueOf(date.atStartOfDay());
}

localDate.format(DateTimeFormatter.ofPattern("dd/MM/yyyy"));

    LocalDate date = LocalDate.now();
    DateFormat formatter = new SimpleDateFormat("dd-mm-yyyy");
    try {
        Date utilDate= formatter.parse(date.toString());
    } catch (ParseException e) {
        // handle exception
    }

这对我来说很管用:

java.util.Date d = new SimpleDateFormat("yyyy-MM-dd").parse(localDate.toString());
