Read Date From File / Calculate And Then Displays That Data In Table Format On Screen

Apr 22, 2015

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 {

JDBC :: How To Determine DATE Data Type Of Parameter If It Is Not Specified

Feb 2, 2015

Oracle JDBC driver determine the DATE data type of parameter correctly without any typecasting.

Example:
ps = conn.prepareStatement("SELECT ? FROM DUAL");
ps.setObject(1, Date.valueOf("2014-01-11")) ;
 
I have tried the same example with other database driver but it gives error.

PostgreSQL JDBC driver:
org.postgresql.util.PSQLException: ERROR: could not determine data type of parameter $1
 
ps = conn.prepareStatement("SELECT ?");
ps.setObject(4, Date.valueOf("2005-01-01"));
 
so I want to know how Oracle JDBC driver determine the DATE data type of parameter.

Java Date Format Conversion

Jun 6, 2013

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:

Transform Simple Date Format - Get Calendar Date

Apr 4, 2015

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...

I am looking for 01,02,03 etc...

Converting String To Date And Time MYSQL

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 {

Date Format Changes On Its Own

Jun 9, 2014

<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();

[code]....

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?

Value Format While Reading Excel Data Into Java

Jan 20, 2015

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).

I'm using following files to read excel data.

1. Schema.csv: SheetName,2-int-Double
2. File.xls:

col1 | col2
123 | 869.87929

Sample code:

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?

Cannot Format Given Object As A Date

Jun 4, 2014

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.

String messageDate = (String) mail.headers["Date"];

Output: Wed, 4 Jun 2014 18:30:05 +0800

2. Next I will convert the timezone to EST.

SimpleDateFormat timeZoneConvert = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss Z");

timeZoneConvert.setTimeZone(TimeZone.getTimeZone(" EST"));

String l_MailDateEST = timeZoneConvert.format(messageDate.trim());

Once the code run I encounter the said error.

Changing Format Of Parsed Date

Aug 13, 2014

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.

JSF :: Primefaces Calendar Component Passing Incorrect Date Format

Jan 27, 2015

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 :

XHTML

<p:calendar id="singleDaySchedule" value="#{scheduleMBean.exactDate}"
showOn="button" pattern="MM/dd/yyyy" required="true" requiredMessage="Date is Required"/>
<p:commandButton value="Submit" update="form" actionListener="#{scheduleMBean.showSchedule}" icon="ui-icon-check" />

[Code] ....

I found out that we need to use <f:convertDateTimePattern> instead of how I am using currently.But I am not able to figure out where to use

<f:convertDateTimePattern>

in my case

Creating New Data Type VeryLargeInteger With / Without Premade Java Classes

Jan 22, 2014

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;

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..
