java如何获取当前精确时间

java获取当前时间精确到毫秒 new SimpleDateFormat("yyyyMMddHHmmssSSS") .format(new Date() );方法2：Calendar Cld = Calendar.getInstance();int YY = Cld.get(Calendar.YEAR) ;int MM = Cld.get(Calendar.MONTH)+1;int DD = Cld.get(Calendar.DATE);int HH = Cld.get(Calendar.HOUR_OF_DAY);int mm = Cld.get(Calendar.MINUTE);int SS = Cld.get(Calendar.SECOND);int MI = Cld.get(Calendar.MILLISECOND);String curTime = YY + MM + DD + HH + mm + SS + MI; Calendar cal = Calendar.getInstance();java.util.Date date = cal.getTime();SimpleDateFormat sdFormat = new SimpleDateFormat("yyyyMMddhhmmssSSS");String myTime = sdFormat.format(currentTime);2014-04-21

import java.text.SimpleDateFormat;import java.util.Date;public class Test { public static void main(String[] args) { SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//设置日期格式 System.out.println(df.format(new Date())); }}2014-04-21

System.out.println(currentDate);2014-04-21

new Date()2014-04-21
