您可以使用SimpleDateformat更改日期字符串

sdf = new SimpleDateFormat("yyyy-MM-dd"); String strDate = "2000-01-01"; Date Date = sdf.parse(strDate);

试试这个

String date = get_pump_data.getString("bond_end_date");
DateFormat format = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
Date datee = (Date)format.parse(date);

String str_date = "11-June-07";
DateFormat formatter = new SimpleDateFormat("dd-MMM-yy");
Date date = formatter.parse(str_date);

我致力于将String解析为LocalDateTime。我把它留在这里作为例子

LocalDateTime d = LocalDateTime.parse("20180805 101010", DateTimeFormatter.ofPattern("yyyyMMdd HHmmss"));

我得到了

字符串到日期的转换:

private Date StringtoDate(String date) throws Exception {
            SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd");
            java.sql.Date sqlDate = null;
            if( !date.isEmpty()) {

                try {
                    java.util.Date normalDate = sdf1.parse(date);
                    sqlDate = new java.sql.Date(normalDate.getTime());
                } catch (ParseException e) {
                    throw new Exception("Not able to Parse the date", e);
                }
            }
            return sqlDate;
        }

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
Date date;
try {
    date = dateFormat.parse("2013-12-4");
    System.out.println(date.toString()); // Wed Dec 04 00:00:00 CST 2013

    String output = dateFormat.format(date);
    System.out.println(output); // 2013-12-04
} 
catch (ParseException e) {
    e.printStackTrace();
}

这对我来说很有效。
