Hey guys, Please help me with this problem asap.When an adress is entered in a textfiled in a texbox after pressing enter,it gets stored in the database with the newline character which shows a small box.How do i remove this new line from the adress in java. Thanks Reply soon Snehal > Hey guys, > [quoted text clipped - 6 lines] > Reply soon > Snehal If the new line is at the end you could use: String text = textField.getText(); text = text.substring(0, text.length() - 1); // now store it in database Best regards, Kovi  Signature-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~ | Gregor Kovac | Gregor.Kovac@mikropis.si | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | In A World Without Fences Who Needs Gates? | | Experience Linux. | -~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~ you may want to look at the method String.replaceAll(String regex, String replacement) If you have the String from the textbox in the variable "tb" you could do tb=tb.replaceAll("\n",""); i.e. "replace all newlines by "" " If that does not work it may be that your newline characters are actually not \n characters, but something else. In that case you have to replace \n for the actual newline character. /philipp P.S.: just a sidenote for further posts: usually people react quite annoyed on sentences like "(...) help me with this problem asap (...)". I would avoid that _especially_ if I am in a hurry :-) sne schrieb: > Hey guys, > [quoted text clipped - 6 lines] > Reply soon > Snehal "sne" wrote... > When an adress is entered in a > textfiled in a texbox after pressing enter, > it gets stored in the database with the newline > character which shows a small box. How do i > remove this new line from the adress in java. One option is to use .trim(); ...on the String before storing it to the database, which not only removes the newline character from the end, but removes all leading and trailing whitespaces. // Bjorn A Hey guys, I hv alredy tried replacing any occurence of \n or ascii codes 13 or 10.bt it doesnt work.the data is retrieved from the oracle database with a small box.

I ended up converting the String to char[] and running through the array, removing \n by hand. Perhaps you have a similar issue here (but I guess the more probable reason is that the newline isn't a \n, but something else?) /philipp sne schrieb: > Hey guys, > [quoted text clipped - 23 lines] >> >> Inviato da X-Privat.Org - Registrazione gratuita http://www.x-privat.org/join.php Ya the newline is nt \n tats fr sure. so wt cn b done. nd replaceall doesnt work on jdk1.3 so cnt use tat > Ya the newline is nt \n tats fr sure. so wt cn b done. nd replaceall > doesnt work on jdk1.3 so cnt use tat J xb dnt f the other wq i, dvs ej uW!

That saved you 1 second in typing, and added 10 seconds to the read time each of the 100 odd people who read your post.

Perhaps the problem is due to a simple misunderstanding of what exactly trim() does... Most importantly, trim() does *not* change the string you call it on, it *returns* a trimmed copy of the original. Remember, Strings are immutable. So this will not work: String s = getString(); s.trim(); // leaves s unchanged database.addString(s); but this will: String s = getString(); String t = s.trim(); database.addString(t); and this: String s = getString(); database.addString(s.trim()); /gordon Signature[ do not email me copies of your followups ] g o r d o n + n e w s @ b a l d e r 1 3 . s e I cnt change the data befre it enters the databsae.i hv 2 remove the newline from the data retrieved from the database > I cnt change the data befre it enters the databsae.i hv 2 remove the > newline from the data retrieved from the database You *could* try to understand the point I was trying to make about trim() and come to your own conclusions.

Remember, > Strings are immutable. And the same goes for s = s.replace('\r').replace('\n') If still neither trim or replace works, you should try to "debug the string", in order to see what character it really is, e.g.: int c = s.charAt(s.length()-1); System.out.println(c); // Bjorn A >Please help me with this problem asap.When an adress is entered in a >textfiled in a texbox after pressing enter,it gets stored in the >database with the newline character which shows a small box.How do i >remove this new line from the adress in java.
