Question

I have this problem converting java.sql.Timestamp.toString back to java.sql.Timestamp. Given element = "2012-08-01 00:00:00.0" and using the code below would return a ParseException telling that element is an Unparseable date.

import java.sql.Timestamp
import java.text.SimpleDateFormat

Timestamp string_timestamp(String element) {        
  if(!date)
    return null 
  SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy")
  // error lies here! //
    Date parsedDate = dateFormat.parse(date)
  return new Timestamp(parsedDate.getTime())
}

Is there a way to convert java.sql.Timestamp.toString() back to java.sql.Timestamp?

Using Date is a bad idea. Date does not handle TimeZone format etc well. See if you can use Calendar Object. Also note that something like date.getYear() will give you 2012-1900 and not the year as you expect. I gave you an example using Date below :a

import java.sql.Timestamp;
import java.text.SimpleDateFormat;
import java.util.*;

class ABC {

public Timestamp string_timestamp(String element) throws Exception  {        
  //if(!element)
    //return null; 
  SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.S");
  // error lies here! //
    Date parsedDate = dateFormat.parse(element);
  return new Timestamp(parsedDate.getTime());
}

public static void main(String[] args) throws Exception {
  ABC a = new ABC();
  System.out.println(" Value = " + a.string_timestamp("2012-08-01 01:12:56.0"));
}
}
