Some suggestions first:
1. Please format your message properly because it is almost unreadable. What's with all those spaces everywhere? And please don't write full sentences in uppercase, this is considered rude.
2. People here are not paid to answer questions, so don't ask "plz send me urgent". This is also considered very rude.
Now to your question. What is FTL exactly ?
Anyway, as far as I understood, you have a String containing a date with a specific format, and you would like to check that the format is correct. Am I right ?
If yes, have a look at the SimpleDateFormat[^] class, and its parse method.

HI ,
I am new to java programming.
We have a website in which login file is to be implemented with "Remember password" functionality. Please guide me how to do it.

Hi
I need to encrypt the plan text using AES algorithm in java and decrypt the encrypted text using C.Any please give solution ASAP.
Thanks

You could do worse than starting here[^] with your encryption. I'm sure it would not take too long to find the corresponding C code for the decryption phase.

Hey guys
I have another elementary problem that needs solving. In the program, after you enter your date of birth (e.g. 14/08/1977), the program takes the month out, and gives you a vacation period in that month.
I'm using a long if statement, with a string value assigned to each month. The if statement pretty much goes if, else if, else if...and so on. Am I using the substring method incorrectly?
if(DOB.substring(3,5) == "01")
{
System.out.println("Holiday Month: " + month1 + "\n" + "Days: " + DOB.substring(3,5));
}

Not as far as I can see (see here[^]). However your output string will show the month number after the "Days: " field; this may not be what you want.

Your use of substring is correct, but the test for the String value is not:
DOB.substring(3,5) == "01"
This is wrong because you are testing to see if DOB.substring(3,5) and "01" are the same object instance. In fact, they are not. They are two different String objects so even if they both have the same value this test will return false. You want to use the equals method to test the String value.
String s1 = new String("01");
String s2 = new String("01");
if (s1 == s2)
if (s1.equals(s2))

Thanks David...that makes a whole lot more sense now!
This website is a great resource, and I appreciate the help. Software is the core of the computer industry. Ok well, that's another huge debate...
I've been studying programming for two years now, and I'm really loving it. A friend recommended this website to me, and I've yet to feel disappointed. I'm glad there are a few knowledgable (and willing) people to help out here!
I good friend once told me once that, "A sign of a good programmer, is someone who'll work an eight hour job. He'll come home, have dinner, and get behind his computer and continue coding."
Just a thought

Hi
I've been facing problems with this new type of connection, and I want some examples on how to establish a serial connection between my phone (SE w910i) and my laptop, through bluetooth. I'm not an expertise on this topic, even on this programming language. It was better if I could make java applets in C#

Hi guys,
I have had some java software written for me that hits a web address and passes through a date/time value in the format of:
YYYYMMDDHHmmSS
Most of the time the date/time comes through correctly... but for some reason it "randomly" sends a through date/time values that are 50 days in the future...
The data gets sent through every 15 seconds and the data will be correct at 10:00:00 but then 15 seconds later I'll get 17:30:22 50 days in advance... and then the date/time value increments by 15 seconds, but still 50 days the future... it will also then "randomly" come good again... now this isn't an odd one here and there, it's right for a while, then will run the rest of the day sending the wrong time...
Does this make sense...???
The problem is I can't reproduce it at will... I know, I know, I'm a programmer and that is the first thing I ask my users to do.. Give me repro steps... but I can't figure out how to reproduce it...
I've tried setting the phone date/time back to a time just before when it has happened in the past, but then the software just works.. it sends the correct time values right through the previous problem window...
Now the only other thing I could think of was that the phone does something "odd" with time calculations or stores the date/time in a funny way internally that wouldn't be necessarily visible to the developer...
I'm clutching at anything I can at the moment because my boss is starting to get shirty about this bug...
Here is the code that I'm told is being used to formulate the date/time value ready for sending via the URL:
private String getTimestamp() {
String time = "00000000000000";
try {
Calendar ca = Calendar.getInstance();
ca.setTime(new Date(System.currentTimeMillis()));
int year = ca.get(Calendar.YEAR);
String syear = Integer.toString(year);
int month = ca.get(Calendar.MONTH) + 1;
String smonth = month < 10 ? "0" + Integer.toString(month) : Integer.toString(month);
int day = ca.get(Calendar.DAY_OF_MONTH);
String sday = day < 10 ? "0" + Integer.toString(day) : Integer.toString(day);
int hour = ca.get(Calendar.HOUR_OF_DAY);
String shour = hour < 10 ? "0" + Integer.toString(hour) : Integer.toString(hour);
int min = ca.get(Calendar.MINUTE);
String smin = min < 10 ? "0" + Integer.toString(min) : Integer.toString(min);
int second = ca.get(Calendar.SECOND);
String ssecond = second < 10 ? "0" + Integer.toString(second) : Integer.toString(second);
time = syear + smonth + sday + shour + smin + ssecond;
} catch (Exception e) {
}
return time;
}
As stated in the Subject here... this is happening on two different Nokia 2323 phones... unfortunately I don't have another nokia phone to test this on to see if its a specific 2323 problem or a Nokia problem...
HELP ME PLEASE..!!!!
If anyone has a suggestin, no matter how crazy, I'm willing to try it out...
Has anyone ever come across this issue before...
If you need more clarification or have questions... shoot them through...
Thanks
** I'm not crazy.. Just ask my toaster **

I've run your code on my PC and it seems to work fine. The only thing I can suggest is to check the value returned from System.currentTimeMillis() which is being used to seed the calendar object.

G'day,
Thanks for the quick reply...
The code does work most of the time.. that's the problem... it'll work for minutes/hours/days, so a quick couple of tests will probably return a correct answer...
What do you mean to "check the value returned from System.currentTimeMillis()"...???
Is there a "better" value to use...???
Why does the calendar object need a seed value...??? I'm a vb.net developer so please excuse my ignorance in this langauge and forum..
Thanks

Member 2119945 wrote: Why does the calendar object need a seed value...???
It doesn't. By default, Calendar.getInstance() will return a calendar object initilised to the current date and time, using the current timezone and locale. The J2ME Calendar is a cut-down version of the J2SE class with some methods removed but it has the same default constructor.
Member 2119945 wrote: What do you mean to "check the value returned from System.currentTimeMillis()"...???
Well, the code that you have posted looks correct, there are no errors in the code. So, if there is nothing wrong with the code, the obvious next point to investigate is the value which you are using to seed the calendar. If you put the wrong value in at the start of the process, you will get the wrong value out at the end.
Is it possible that for some reason System.currentTimeMillis is returning the wrong value? Not sure why that would happen (time zones?), but I agree with Richard and that would be the next thing I check. That's not so easy to do if this is happening unpredictably, I agree.
Maybe you could search the Nokia S40 forums to see if anyone else has any issues with currentTimeMillis (S40 may not be the correct platform for this phone type - I'm not sure but you get the idea).

Hi David,
Are you saying that the following line is not really needed...???
ca.setTime(new Date(System.currentTimeMillis()));
If the .getInstance method returns an initialised object with the phone's current data and time, why use it at all...
Thanks

Most of your code is not needed, try this:
private String getTimestamp() {
try {
Calendar ca = Calendar.getInstance();
SimpleDateFormat df = new SimpleDateFormat("yyyyMMddHHmmss");
String stime = df.format(ca.getTime());
System.out.printf("%s\n", stime);
} catch (Exception e) {
}
return stime;
}
[edit]As David Skelly points out below, SimpleDateFormat is not available on the 2323, but there may still be a somewhat less complex method you can work on. I'm reasonably sure you do not need to use the System.currentTimeMillis() function after obtaining the Calendar object.[/edit]

Is SimpleDateFormat supported in J2ME?

Looks like it according to this[^].

But according to this[^] the Nokia 2323 only supports CLDC and MIDP, not CDC, in which case SimpleDateFormat is not available.
It's a minefield. So much for WORA.

Hi All...
Thanks for your help...
Ive had the .setTime line removed from the code and will test it..
I'm not sure why the extra lines of code were added in there.. it does seem a little convoluted way to achieve sending of a date/time value, but if it works, I'm happy...
Thanks heaps for pointing me in the right direction..
Regards

Hello Friends
I am using some images as background in my application.I want when I send that jar file to someone else then I dont need to send that files with jar file.So,where do I need to add my Images?In which Folder Do i need to add them so that while creation of jar file they also get bundle into it.I m using Netbeans6.7.1
I googled but not any proper anser found.
Any Ideas??
Thanks & Regards
Yogesh

Hey Guys
I found the solution.First Create a image folder in src folder.Then go to Project properties in Netbeans.Select Library,Add jar folder and then add that Image folder.And after that
Here is the code below:
URL myurl = Thread.currentThread().getContextClassLoader().getResource("Images/Logo.jpg");
ImageIcon im = new ImageIcon(myurl);
Anyway,thanks who viewed my Question.
Very fast starting on Monday At Work
Regards
Yogesh.

Hi guys,
I've got an issue here. I've created an application in Java that uses the DatagramSocket and DatagramPacket classes to send the byte array of data through the UDP protocol.
On the other hand, I'm trying to experiment using an Visual Basic application to receive the sent byte array of data.
However, I'm not sure whether if the received data is the correct one. How do I verify the data?
I'm using both the applications in windows PC, so there's is'nt a need to decode in Big Endians format.
I'm sending the byte array of data in different sizes. I've tried to output the sent data in String format in Java.
This is what I get:
eg.
byte[] data = s.getBytes();
System.out.println(data)
where s is a string variable that holds the converted byte arraydata.

Well only you can answer that. You know what the data is, what format it is in, whether it is character (MBCS or Unicode) etc. So add some code at either end to check that you receive what you expect. Maybe precede each UDP packet with a length word so the receiver knows how many bytes it should receive, add a check digit at the end etc., etc.
