java如何实现各国时间格式转换成yyyy-MM-dd HH:mm:ss时间格式？

Posted 2023-04-16

如题：比如：Mon 25.08.2014 18:17 还有August 16, 2014 , 7:46 am

等等，急急急....

SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy年MM月dd日 hh时mm分ss秒");
Date d = new Date();
String timeStr = sdf1.format(d)//结果就是这种格式：2014-08-08 08:08:20
String timeStr2 = sdf2.format(d)//结果就是这种格式：2014年08月08日 08时08分20秒

参考技术A 不管是哪个国家的, 只要是java.util.Date, 就可以使用　new SimpleDateFormat("yyyy-MM-dd").format(new Date())来格式化本回答被提问者采纳 参考技术B public static void main(String[] args) throws ParseException
SimpleDateFormat sdf1=new SimpleDateFormat("yyyy年MM月dd日 HH时mm分ss秒");
SimpleDateFormat sdf2=new SimpleDateFormat("yyyy/MM/dd HH:mm");
SimpleDateFormat sdf3=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

Date now=new Date();

// System.out.println(sdf1.format(now));
// System.out.println(sdf2.format(now));
// System.out.println(sdf3.format(now));

String d="2014-06-01 21:05:06";
SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

Date date = sdf3.parse(d);
System.out.println(date);

参考技术C * 将日期对象转换为字符串格式
*/

Date date = new Date();
//自己创建的自定义的格式化对象。
DateFormat dateformat = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss"
);

//调用格式对象中的格式方法，将日期对象转换为字符串
System.out.println(dateformat.format(date)); 参考技术D SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

RSA的密钥把JAVA格式转换成C#的格式

把C#格式转换成Java：RSA的密钥把JAVA格式转换成C#的格式(1)

我已经在第一篇介绍过如何把C#格式转换成Java，现在来看看如何把Java格式转换成C#。
