使用Java进行时间格式化 在Java中,可以使用SimpleDateFormat类轻松实现时间的格式化。以下是一个示例代码,演示如何将当前时间格式化为“yyyyMMddHHmmss”格式: importjava.text.SimpleDateFormat;importjava.util.Date;publicclassTimeFormatter{publicstaticvoidmain(String[]args){// 获取当前日期时间Datenow=newDate();// ...
importjava.text.SimpleDateFormat;importjava.util.Date;publicclassDateFormatExample{publicstaticvoidmain(String[]args){// 获取当前日期DatecurrentDate=newDate();// 创建一个日期格式化的对象SimpleDateFormatformatter=newSimpleDateFormat("yyyyMMddHHmmss");// 将当前日期格式化为指定格式StringformattedDate=formatte...
import java.text.SimpleDateFormat; import java.util.Date; public class TimeFormatter { public static void main(String[] args) { // 创建SimpleDateFormat对象,并设置日期时间格式为"yyyymmddhhmmss" SimpleDateFormat formatter = new SimpleDateFormat("yyyymmddhhmmss"); // 获取当前时间 Date now = new ...
Date date=newDate();longdate_3_hm = date.getTime() - 3600000 * 34 *day; Date date_3_hm_date=newDate(date_3_hm);returndate_3_hm_date; }1.12字符串 yyyyMMdd HHmmsspublicstaticString getStringToday() { Date currentTime=newDate(); SimpleDateFormat formatter=newSimpleDateFormat("yyyyMMdd ...
public static String dateToStrLong(java.util.Date dateDate) { SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String dateString = formatter.format(dateDate); return dateString; } /** * 将短时间格式时间转换为字符串 yyyy-MM-dd ...

String strBeginDate = dateTimeformat.format(new Date());System.out.println(strBeginDate);//以上返回的是24小时制的时间 显示应该用下面的这个，因为12小时制的结果无法区分是上午还是下午 SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");Date date = sdf.parse("20111212133712");...
