SimpleDateFormat    sDateFormat    =   new    SimpleDateFormat("yyyy-MM-dd    hh:mm:ss");       String    date    =    sDateFormat.format(new    java.util.Date());     如果想获取当前的年月,则可以这样写(只获取时间或秒种一样):Java代码 [java] view plaincopyprint? SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM");    String date=sdf.format(new java.util.Date());     当然还有就是可以指定时区的时间(待): [java] view plaincopyprint? df=DateFormat.getDateTimeInstance(DateFormat.FULL,DateFormat.FULL,Locale.CHINA);  System.out.println(df.format(new Date()));
