How To Get Date Data Type From MySQL To Java Format
May 22, 2012
In my project i am facing an problem, The My SQL Data base will accept the date format of yyyy/mm/dd only as "Date" data type but in my program i wants to use dd/mm/yyyy format. (i have this same format now) that's why I am unable to insert / retrieve it..
The intent of the code is to read date from a file, does calculation and then displays that data in a table format on the screen. Then creates another file with those values:
Reads file: Beginningbalance.txt Displays Data with calculation Creates a file called "Newbalance.txt" with the following values:
111 251.41 222 402.00
With the way the code is written I can get it to create the file but it only displays one of the customers (111). I know that I need to create a loop but I am not sure how to build that. I tried creating another while loop and changing it to outFile but that was without success.
import java.io.*; import java.util.Scanner; import java.text.DecimalFormat; public class Output { public static void main(String[]args) throws IOException {
I have a piece of code as below for date format conversion.
DateFormat formatter1 ; DateFormat formatter2 ; Date date = new Date();
formatter1 = new SimpleDateFormat("yyyy-mm-dd"); date = formatter1.parse("1952-12-10"); System.out.println("before format, date is " + date);
formatter2 = new SimpleDateFormat("dd-MMM-yy"); formatter2.format(date); System.out.println("after format, date is " +formatter2.format(date));I would like to change 1952-12-10 become 10-DEC-52, h
However, I am getting below output:
before format, date is Thu Jan 10 00:12:00 MYT 1952 after format, date is 10-Jan-52
Given a Date such as this sampleDate (120, 08, 02), does SimpleDateFormat transform this given sampleDate using (sampleDate.get(Calendar.DATE)) ?
Issue is that without the SimpleDateFormat the days are outputting correctly but starting with 1,2,3,4 etc and when I apply the SimpleDateFormat to the above Date I only get 01,01,01 etc...
In my java file I made Strings of date and time, but my MYSQL database needs Date and Time of course. I've tried to convert them, but I keep getting this exception: org.apache.jasper.JasperException: java.lang.NumberFormatException: For input string: "2013-02-20"
public class Vogel { static final String url = "jdbc:mysql://localhost:3306/turving"; public static void Insert(String datum, String tijd, String plaats, String spotternaam, String vogelsoort) { try { SimpleDateFormat format = new SimpleDateFormat("YYYY-MM-DD"); SimpleDateFormat formatt = new SimpleDateFormat("HH:MM:SS"); java.util.Date parsed = format.parse(datum); java.util.Date parsedd = formatt.parse(tijd); java.sql.Date sql = new java.sql.Date(parsed.getTime()); java.sql.Time sqll = new java.sql.Time(parsed.getTime());
<script type="text/javascript"> function CompareDates(id) { var monName = new Array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sept", "Oct", "Nov", "Dec"); var d = new Date(id); var curr_date = d.getDate();

why the default date format that the textbox accepts is in 'mm/dd/yyyy'.For example if i entered "13-05-2014" then it would return an error stating date is invalid.If i entered "12-05-2014" then it would return "5 Dec, 2014".I did not declare any dateformat anywhere except for the datepickers which as shown above, is 'd MMM, yyyy'.Before this happened i trialed and error many different kind of codes to try to validate the date however it all didnt work and so i reverted it all back to the original codes.Last time the dateformat that the textbox accepted was 'dd/mm/yyyy' and it worked fine with my javascript function except the validation part.
Now it still works except that the dateformat changed to 'mm/dd/yyyy'.I did try to use console.log to find out what's wrong but there were no error messages.Why has the dateformat changed by itself?
I am reading Excel data using java apache. I got format issue while reading double value such as 869.87929 (in excel) into 869.8792899999999 (in java).
if(type.equals("Double")){ String str = content[i-1]; //System.out.println(str); BigDecimal d = new BigDecimal(str); listObjects.add(d); }
Note: type from schema.csv & content [] value from file.xls If I print **str**, it shows value as 869.8792899999999. But i need to get **str** value as 869.87929. How can I get it?
When trying to convert the time zone of a date I encountered the log below. java.lang.IllegalArgumentException: Cannot format given Object as a Date..Here is what my code looks like:
1. First I will get the date from the email header by the following code.
I've created a method named parseStringToDate this method takes a string parameter and parse it to the date: here is my code:
public Date parseStringToDate(String date) throws ParseException{ DateFormat formatter = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.SHORT, Locale.getDefault()); return formatter.parse(date); }
i'm trying to parse a String to date then:
public static void main(String args[]) { MyDate a = new MyDate(); try { Date d = a.parseStringToDate("Wednesday, August 13, 2014 3:33 PM"); System.out.println(d); } catch (ParseException e) { e.printStackTrace(); } }
As i've defined DateFormat in the method, now i'm passing it a date accordingly: "Wednesday, August 13, 2014 3:33 PM" And the output is: Wed Aug 13 15:33:00 PKT 2014
Which is not equal to the format i gave it.. how can i change its format to same as i've given input. InShort i want to parse a string to date and it should convert that String to date with exactly the same format.
I have a date in the following String format "2013-03-28,19:37:52.00+00:00" and post processing I am converting this to following String as per prevailing logic "2013-03-28,19:37:52.00+0000" (This is existing code and no changes have been Made here for last few years) And the using this SDFormat i.e new SimpleDateFormat("yyyy-MM-dd,HH:mm:ss.Sz") for conversion to Date Object
We are suddenly getting this exception now can't figured out what has changed ?
java.text.ParseException: Unparseable date: "2013-03-28,19:37:52.00+0000" at java.text.DateFormat.parse(DateFormat.java:357)
I am using the calendar component of the primefaces and I am using the attribute pattern="MM/dd/yyyy.But when I print the values in my MBean along with the selected date event the timeZone (i think) is printed as Sun Mar 29 00:00:00 IST 2015 I do not understand why its printed even though I have set the pattern.Part of my code :
What I'm doing about it: googling the shit out of my problems, consulting you fine readers, consulting my friends, and yesterday I signed up for Lynda.com. I'm hoping 30hrs+ or so of watching, rewatching, and analyzing the example code will catch me up before I get too behind in CS302
** Assignment Prompt **
Integer types are very convenient, but their limited width and precision makes them unsuitable for some applications where precision is more important than speed. Develop a class VeryLargeInteger that can handle arbitrary long integer numbers (both negative and positive) and the basic arith- metic operations (addition, subtraction, multiplication, division, and remainder).
Hint: The number could be represented as string, the sign could be represented either as boolean or as part of the string.
Note: Implementations of addition/subtraction through repeated use of a constant incremen- t/decrement will not be accepted. Implementations of multiplication and division that rely only on addition and subtraction will not be accepted.
I know I'm going to have to create a separate tester to call on the VeryLargeInteger class and it's math methods. For the new data type, should I convert the integer/string into an array in order to handle the large length of the number? I know he wants us to use recursion for the math methods. My gut tells me addition and subtraction will be slightly easier than multiplication and division. I know I'll have to reference the other methods for division. We aren't allowed to use the BigInteger class.
How I should construct any of the methods.
Java Code:
import java.util.ArrayList; /** ∗ VeryLargeInteger (VLI) is a class for arbitrary precision integer computation */ public class VeryLargeInteger { private int[] num1; private int[] num2; private int[] num3;
I'm trying to show mysql data in JSF using this example [URL] .... . I figured out what <h:dataTable value="#{userBean.getUserList()}" var="u" border="1"> must be <h:dataTable value="#{userBean.userList}" var="u" border="1"> but getting error:

I have a jtable. the fields are like Product_code,Product_name,Qty,Rate in my java program.. now i want to do is when i press a first letter in my jtable under Product_name like "P" it will display the reminding Product_name which will have the starting letter of "P" like pen, pencil, peper like this i want to populate in my jtable.
I am developing my college's project in JSP using jquery to open a magnific popup when user clicks on a link and the in the magnific Popup must be fetched from Mysql and i tried two approaches for this:
1. magnific Popup type is ajax here i passed the variable value in the link of href (after '?') to another JSP page where connection to database is created and queries are written in JSTL to fetch data and show this in magnific Popup .. But i failed in this approach, don't know in another JSP page the data without having database connection is loaded in the magnific Popup easily but not database data..
2. magnific Popup type inline here i need to pass the variable value in the same page between different tags..
