日期格式转化

//String转Date
DateFormat format1 = new SimpleDateFormat("yyyy-MM-dd HH:mm");
try {
Date date1 = format1.parse("2013-11-13 13:13");
System.out.println(date1);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

//Date转String
Date date = new Date();
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String str = format.format(date);
System.out.println(str);
