String、java.Util.Date和java.sql.Date之间的转换

SimpleDateFormat sdf =  new SimpleDateFormat("yyyy-MM-dd");  /**yyyy-MM-dd为字符串的格式**/
String stringToParse = "2007-7-12";  /**要转化为java.util.Date的字符串**/
try {
java.util.Date date = sdf.parse(stringToParse);
java.sql.Date sqlDate = new java.sql.Date(date.getTime());
System.out.println(sqlDate.getTime());
}
catch (Exception ex) {
System.out.println(ex.getMessage());
}

String birthday = request.getParameter("birthday");
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
java.util.Date date = format.parse(birthday);
java.sql.Date birthdaydate = new java.sql.Date(date.getTime());

java.sql.Date date=new java.sql.Date();
java.util.Date d=new java.util.Date (date.getTime());
