常用功能之SimpleDateFormat 不同格式之间转换

public static void main(String[] args)throws Exception {
String date = "2005-01-12 00:00:00.000";
SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy-MM-dd");
Date d2 = sdf2.parse(date);
System.out.println(d2.toLocaleString());

SimpleDateFormat sdf3 = new SimpleDateFormat("yyyyMMdd");
date = sdf3.format(d2);
System.out.println(date);
}
