How to remove new line from string

I have a string say following
String line = "one\ntwo\nthree";Now i am trying to remove new line from string. For this i did following
String txt = line.replaceAll("\\n","");But i see still new line is occuring. Is it correct way. Please advice me.

Ok. I was just using \n instead of \r\n. And i am in windows. I will give a try with \r\n
Ok i tried using following , but it doesnt work.
line = line.replaceAll("\\r\n","");Am i missing anything here. Please guide me.

How to remove new line character from query output?

Hi,
How to remove new line character from query output?
have tried select replace(column_name, CHR(10), ' ') from table_name.
Edited by: GreenHorn on Sep 11, 2008 12:53 AM

Please consider, that windows uses a sequence of chr13||chr(10) Unix uses only one character chr(10).
The new line character(s) may be OS-dependent.
You could consider both with:
replace(replace(column_name, CHR(13)||CHR(10), ' '),CHR(10),' ')

How to remove characters/lines from the beginning of an InputStream

Hi,
I have a program which receives several InputStreams. From each of these streams I have to remove 2 lines from the beginning. After the lines are removed, all the streams are combined to one with SequenceInputStream and read in one chunk. Is there an easy/simple way of doing this?
One option I thought would be to read the char by char until 2 end of line chars have been detected and then read the rest of the data to a buffer. And the create a ByteArrayInputStream out of this buffer. Problem with this approach is, that the amount of data can be large, so putting all the data in to memory might cause problems.
Another option is to use BufferredInputStream and use the readline() method twice to get rid of the lines that are not needed. After this I would write the data to some output stream, which is then converted back to input stream. Propably would work, but sound too much of work for a simple thing like this. There has to be better way.
To make it simple, what I need is a method that looks like the following, or something similar
* Removes n number of lines from the beginning of a InputStream.
* @param is InputStream where the lines are removed
* @param numberOfLines int value to indicate how many lines whould be removed
* @return InputStream where lines have been removed.
public InputStream removeLines(InputStream is, numberOfLines);Thanks.

Here's the code, feel free to use it. Comments are also welcome.
public InputStream removeLinesFromTheBeginning(InputStream is, int numberOfLines) throws IOException
          char c = 'c';
          int i = 0;
          for(int n = 0 ; n < numberOfLines ; n++)
               do
                    c = (char)is.read();
                    System.out.print(c);
                    if(c == (char)-1)     // end of stream reached before any newline characters were found.
                         return null;
                    i++;
               while(c != '\n');
               System.out.println();
               System.out.println("Characters removed:" + i);
               System.out.println("n: " + n);
               i = 0;
          return is;

either this way we can do this
1)
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
<b> factory.setIgnoringElementContentWhitespace(true); </b>
DocumentBuilder db = factory.newDocumentBuilder();
or
2)
java.io.StringWriter sw = new java.io.StringWriter();
StreamResult sr = new StreamResult(sw);
t.transform(new DOMSource(doc), sr);
String xml1 = sw.toString().trim();
<b> xml1=xml1.replaceAll("\\s",""); </b>
System.out.println(xml1.trim());

can somebody in the forum give me idea how to remove comma from the String and
have a string without comma.
Thanks

int idx = oldString.indexOf(',');
if(idx >= 0)
newString = oldString.substring(0, idx) + oldString.substring(idx + 1);or for jdk 1.4 and later
str = str.replaceAll(",", "");

How to removed dashed lines from "Page Break View"?

Hi,
In Excel 2010, I found that once “Page Break View” is selected, there will be dashed lines across the view even after returning to “Normal” view. These dashed lines can be distracting.
Is there a way to remove them?
Bob

Yes use
File -> Options -> Advanced
Scroll down to Display options for this worksheet and remove the tick in Show Page breaks.
Unfortunately it's sheet specific so you'll have to do it everytime it happens until you've done all the sheets.
Unless you develope some VB to do it for you,

How to make new line in JButton.setText()?

how to make new line in JButton.setText()?
I want to set the text of jbutton in tow line ,as follows
| jbutton-line1 |
| xxxxxxx-line2 |
i konw i can jbtton.settext("<html>line1<br>line2</html>");
but i find it's ugly using html,
is there anyother way to create new line in JButton's Text

As for the above comment....
I thought the question was well purposed. Using HTML was not acceptable in this instance, which was made clear, so why critisize his comments? "Using HTML" is a poor solution, it does NOT work in many instances due to browser, OS variations. Usually the "common answer" is never a COMPLETE answer.
Possible Solution:
Use JLabels to render the text on the button.
import javax.swing.*;
import java.awt.*;
public class ButtonMaker {
public static void makeButton(JButton jb, String[] titleList) {
jb.setLayout(new FlowLayout());
for (int i = 0; i < titleList.length; i++) {
JLabel tmpLabel = new JLabel(titleList);
tmpLabel.setForeground(Color.black);
jb.add(tmpLabel);
public static void clearButton(JButton jb) {
Component[] cList = jb.getComponents();
for (int i = 0; i < cList.length; i++) {
if (cList[i] instanceof JLabel)
jb.remove(cList[i]);
Known Limitations:
1. Flowlayout does not work well with single line text buttons... perhaps another layout manager may work better for various buttonsizes-linenumber combos.
2. Mac OSX : The default UI for Mac OS X (and above it seems), is to have rounded edged buttons. These rounded edges are destoryed when using JLabels, leaving a square, blocky button in its place.
POSSIBLE SOLUTION:
(this is ugly and time consuming)
- create images of the button with text on them.

How to remove a node from nlb at runtime?

hello,
i need to temporally exclude a node from an nlb.
May happen that a server is up and working but the web application i'm balancing is out of sinch with the same application in the others nodes.
Eg. some static variables are not the same of the same static variables of other nodes, because of a timeout, a write error and so on but the server is still working.
in this case i need to stop the server from nlb because the information in the web application is not in sinch with other nodes.
I need to prevent users from being serverd from this out to date server, untill it will became updated, but i need to do this programmatically
how can i do it?

will work.

Removing new line character in jdk 1.2

I am currently using replaceAll("\n", "") to remove new line characters in an string. But this works only for 1.4 version, I know need to have this work on 1.2 and 1.3.
Is there an alternate method that I can use?

If the string come from a file that's in the native text format for that platform, then replaceAll(System.getProperty("line.separator", "") will work.
This won't work, however, if you, say, create a text file on windows and the read it on Unix without translating the EOL characters.
If you can't be certain that the file is in the format that matches the current platform, three options pop to mind:
* Run over the String, char by char, copying all chars to a new String except \r and \n.
* Use two replaceAll calls--one with \r and one with \n.
* Dump the String into a StringReader, then wrap the StringReader in a BufferedReader. Call readLine() on the BufferedReader in a loop, concatenating the results in a StringBuffer as you go.
