How can i convert date to string. Is this the best way
// Create an instance of SimpleDateFormat used for formatting
// the string representation of date (month/day/year)DateFormat df = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
// Get the date today using Calendar object.Date today = Calendar.getInstance().getTime();
// Using DateFormat format method we can create a string
// representation of a date with the defined format.String reportDate = df.format(today);
// Print what date is today!System.out.println("Report Date: " + reportDate);

I would like convert string to date (dd/MM/YYYY) - this is useful for compare dates in TableColumns.
so i use DateTimeStringConverter (the string "01/11/2014" is a value of DatePicker)
DateTimeStringConverter format = new DateTimeStringConverter(Locale.FRANCE,
"dd/MM/YYYY");
Date d1 = format.fromString("01/11/2014");
d1.toString()
I don't obtain the right date but this date = "Mon Dec 30 00:00:00 CET 2013" !!!
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 ?

I have an requirement of splitting a Date-Time String i.e. 2013/07/26 07:05:36 As you observe the above string has Date and Time with space in between them.
Now I want just want split the string not by delimiter but by length i.e. after 10th place and then assign it to 2 variable i.e. Date <----2013/07/26 and Time <---07:05:36 separately.
For this program, I have to run a slot machine. It runs until right before the do while loop and then I receive the error: Exception in thread "main" java.util.InputMismatch.Exception. Searching around, someone said it was a scanner error and adding a call keyboard.nextLine(); fixes the problem- however with that I receive the same error.

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.

For the object arguments in date formatters such as %td, are only calendar objects accepted?
View Replies View RelatedI am trying to display the contents of my Object but when I compile it I get this:proj4.TellerQueue@1db9742
I am pretty sure it's because I havent created my own toString method but I could be wrong. If this is the case, what do I need to do to properly display the variables of my object? Right now my class, BankQueue, contains another object called Person, which contains a String and int variables. I want to do something like this:
class BankQueue{
Queue<Person> q = new LinkedList<Person>();
public String toString(){
return q.;//display contents of the q

but Im not sure how to convert these into Strings.
I have two classes - a reservation class & a main class. Essentially, I want the user to enter two dates: an arrival and departure date. From the two dates, I will do a calculation (num days & price). I am having trouble finding a way to let users enter the (preferably in int, but that wasnt working),use getTime() to convert it from a calender to a date object. Then I want to use the dates to do a calculation. In addition, my constructor is being funky.

I have date in string ex: 2014-08-08T17:38:58.316+05:30 and want to convert into 2014/08/08 17:38:58. I am using below code :
String date1="2014-08-08T17:38:58.316+05:30";
SimpleDateFormat formatter, FORMATTER;
formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
String oldDate = "2011-03-10T11:54:30.207Z";
Date date = formatter.parse(oldDate.substring(0, 24));
FORMATTER = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss.SSS");
System.out.println("OldDate-->"+oldDate);
System.out.println("NewDate-->"+FORMATTER.format(date));
this giving me required value, but when i replace oldDate with date1 it shows me exception that not parse to date. Actually i am getting date in string of 2014-08-08T17:38:58.316+05:30 which i need to convert into date 2014/08/08 17:38:58. To convert into date i am using below code :
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/M/yyyy hh:mm:ss");
Date datecomp1 = simpleDateFormat.parse(String );
The issue is to convert 2014-08-08T17:38:58.316+05:30 into 2014/08/08 17:38:58.

I have got 2 questions on the above class...
1) I get an error "Cannot make a static reference to the non-static field DTStart" wherever i use DTStart in the main method....What's causing this error? and How do i fix it for good?
2) public String DTStart; Once i get the current date & time assigned to the above DTStart String in the main method i cannot use the updated value of DTStart in any other class. In another class i wanna create an instance(object) of this Swipe_In class with DTStart assigned to the current time(as in its main method)..I tried but the object's DTStart gets assigned to null.(( How do i achieve this?
I have this project due and its asking that i print out what type of triangle it is when the user inputs 3 sides. I have most of it done and working, but it pops up different windows instead of using one window for everything. The assignment says it needs all the final info to be in one window. The boolean is coming from another method. I'm unsure how to get it into a string (Or if that's what i have to do). The method must return a boolean true/false.
import javax.swing.*;
public class Triangle {
public static void main(String[] args) {
int side1 = getSides();

In my Java class, the last assignment we had to turn in was to create a program that would take a users input and create a new type of animal. I went through the different steps in the instructions, and everything seemed to be going well up until the point where we actually took the users input and created the new animal. Specifically, I kept getting an error stating that I could convert a String to an animal.
I'm attaching the main class (Animal), one of my animal classes (Bird) and the class where I'm getting the error (AnimalStuff). I turned the program in as is, so what's done is done, but I'd like to learn what I'm doing wrong and what I can do better. I do know that the loop in AnimalStuff is wrong as it doesn't work right either, but I'm more concerned about the conversion from String to animal, as the entire program depended on this to work, and it doesn't.
public class Animal {
/**
* @param args the command line arguments

public static void main(String[] args) {
}
public static String kind;
public static String integument;

Is there anything that jumps out at to what I'm doing absolutely wrong?
I've started writing a new program that Scans for some strings. I want to specify a random Integer to those Strings in order to do my desired idea. what should I do?!! my codes are here :
import java.util.Random;
import java.util.Scanner;
public class Draw {
public static void main(String[] args) {
System.out.println("This Program is written to solve little problems in families cause of doing unwanted works!!");
[code].....
now I want to Specify an Integer to each person that has been scanned! for example if the first person is " David " , which is a String, in the next step :
Random randomNumber = new Random();
randomNumber.NextInt(101);
int David = randomNumber.NextInt(101);
I want to what should I do?
I am obviously new to programming and Java so I set myself the goal of creating a very simple auto type style of program so it gets the users input and relays it out again but potentially to another window (I am currently testing to notepad). The reason I am trying to make it is because i thought it could be quite simple and I can build on it as a project to make it better.
The issue I am having is that it outputs the first character to the window I am selected (again testing into notepad) but then stops and doesn't output anything else. I tried to figure out what was going on by putting a System.out.println(arr[6]); after the delay method but it just output a line so almost like what I was putting into the array was only storing the first character of the string? I cannot figure out why that would be...

I am supposed to write a program on PuTTY using UNIX (I have Windows 8), but I am not comfortable with it yet, so I am using Java through NetBeans (IDE 7.4).
The program has to follow these instructions (ignore the Linux part of the instructions, the rest is in bold):
Write a program on the Linux system using the putty utility. The program should get strings of data from the command line (that is, look for the data in the "args" array of strings). Use a loop to convert each of the strings in the array into a double and add the number to a total. Print the total after all of the strings have been processed.
The program will use try-catch to catch any error that occurs. If an error occurs, the program will print a message saying that the error occurred. The program can end at that point.
You should create the Java program using the nano editor. The input data should be a list of numbers on the line that runs the program.
The problem so far is that I keep getting an error when converting a String value into a new double value. I have yet to code the try-catch method in my program
Java Code:
import java.util.*;
public class Program13Strings {
public static void main(String[] args) {
Scanner scan = new Scanner (System.in);
System.out.println("How many lines of data do you wish to enter?");
int size = scan.nextInt();
[Code] ....
*NOTE: right where my code says double newDouble = Double.valueOf(newResponse); is where the error is occurring.
*ERROR: Exception in thread "main" java.lang.NumberFormatException: For input string: "abc"

How can this be fixed so I don't get this error?
I'm using the class below to encrypt and decrypt data in my program. It works rather well with the exception that I can't for the mind of me get the recreation of the key to work. When the program runs the first time, it creates a key and saves it to Data.txt. This part works fine, and there are no errors, the encryption and decryption works until I reload the program and it tries to recreate the key using the String in the .txt.
read = loadFile.readline();
byte[] data = read.getBytes("UTF-8");
key = new SecretKeySpec(data, 0, data.length, "PBEWithMD5AndDES");
I've looked at:
java - convert Byte Array to Secret Key - Stack Overflow
java - Converted secret key into bytes, how to convert it back to secrect key? - Stack Overflow
and a number of other sites which didn't work, both of these however suggested the key = new SecretKeySpec. The actual key became: "[B@79fe3f51". Whereas the recreated key became: "[B@3e1d1648".So they are close, but not the same.I create the original key like this:
key = SecretKeyFactory.getInstance("PBEWithMD5AndDES").generateSecret(keySpec);
Encryption.java:
public class Encryption {
public Cipher dcipher, ecipher;
// Responsible for setting, initializing this object's encrypter and
// decrypter Chipher instances
