日期比较大小

public static void main(String[] args) throws ParseException {
String date2 = "2013-9-10 0:00:00";
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
  Date date1 = format.parse(date2);
  Date date = new Date();
  long m =  date.getTime();
  long n = date1.getTime();
  if(m> n){
  System.out.println("true");
  }else{
  System.err.println("false");
  }
 
}
