until now i know only how to insert data but not new line.
Thanks in advandce

Hi you can put a new line in a text file using System.getProperty("line.separator"). This implementation will work for every OS.
import java.io.*;
class Demo{
public static void main(String args[]) throws Exception {
FileWriter fr = new FileWriter("FileDemo.txt");
fr.write("AAAAAAAAAA");
fr.write(System.getProperty("line.separator"));
fr.write("AAAAAAAAAAA");
fr.close();
}

Inserting new line to a text file at position #

Hi,.
Is it possible to do this in java?
1. Open a new text File (woutFile)
2. woutFile.write(" line #1\r\n"); // write new line
3. woutFile.write(" line #2\r\n"); // write new line
4.woutFile.write(" line #3\r\n"); // write new line
5. Go to line #2 position on a text file
6. Insert NEW LINE between line #2 and Line #3
7. move to the end-of-file
8.Close the file
Please help

Is it possible to do this? please look at question
inside comments.Your question has already been answered. Beyond that,
if you have some code and you want to know if it will
work, then run it and see.The answer was no. It's one of the fundamental properties of files that you cannot insert content in the middle, just at the end. To insert content you first have to make room for it. In this respect a file works like an array and not like a linked list.

How to insert new line break in XSLT mapping

Hi experts,
I am doing file to mail scenario, i am sending the text file as an attachment using reciever mail adapter.
I did everything, i can able to send the mail with text file attachment, but with in the file i got multiple rows, i need to put line break in XSLT mapping.
I did use following statement but it is inserting small rectangle between the records, the records are not separating with new lines, all are in one line.
<xsl:text>*#xA;</xsl:text>

Hi,
I think <xsl:text>#xa;</xsl:text> should do the trick, but depending on which OS (ux or win), the "new line" chars sequence is different (win would require a CRLF like <xsl:text>#xd;*#xa;</xsl:text>)

How to insert new line in the copied schema with transaction code PE01?

Dear Experts,
I have copied HKT0 to ZKT0 , i want to insert new line between line 150 and line 160 in ZKT0, I don't know how to insert new line 160, who can tell me ?
Looking forward to your reply.
Best Regards,
Merry

Hi,
1. Open your schema,
2. In first colume "Line" select line where you want to add new line,
3. Replace first value in the column field (that indicates number of line) with character I (means insert),
4. Press enter
The line will be added. The same way you can add lines to PCR.
To delete use character D.
Cheers

How to insert new line character?

Hi all,
I have two lines to print.
out.println("Available number of columns="+cols);
out.println("Number of columns must be present=10");My problem is:
i want both the lines to be printed one below the other. But, it is displayed in one single line.....
Can anyone please tell me how to insert new line character?
I tried with \n, '\n' and \r\n but, in vain......
Thanks for your time.
Regards,
Ashvini

You should never use "\n" directly.
The line separator character is different on different operating systems.
And putting quotes around it in your string will make absolutely no difference in the JSP.
To find out what the line separator is you should use System.getProperty("line.separator");
The JSPWriter and PrintWriter classes will automatically use this property with a println statement, so a println will always finish with a line separator.
The issue here was that HTML by default ignores all whitespace.
The solutions provided
- use a <br> tag instead of a carriage return
- use <pre> tags, which tells the browser not to ignore whitespace. That can be troublesome in JSP which generates a lot of extraneous carriage returns into the code.

How to insert new line char while writing bytes into file

Hello Sir,
Is it possible to insert the new line character in set of String variables and stored them into bytearray ,then finally write into File?
This is the sample code which i tried:
             File f = new File(messagesDir,"msg" + msgnum + ".txt");
             FileOutputStream fout = new FileOutputStream(f);
                String fromString = "From:    "+msg.getFrom()+"\n";
                String toString = "To:     "+msg.getTo()+"\n";
                String dateString = "Sent:    "+msg.getDate()+"\n";
                  String msgString =msg.getBody()+"\n";
                String finalString=fromString+toString+dateString+msgString;
                byte[] msgBytes = finalString.getBytes();
                fout.write(msgBytes);
             fout.close();in the above code , i tried to add the new line as "\n" in end of each string. but when i look into the generated files msg1.txt , it contains some junk char [] .
please provide me the help
regards
venki

but it has still shown the the junk char, its not able
to create the new line in the created file i am afraid
how am i going to get the solution?:(Do not be afraid dear sir. You are obviously using a windows operating system or a mac operating system. On windows a newline is "\r\n" not '\n', and on a mac a newline is '\r', not '\n'. If you make that correction, dear sir, your program will work.
However, there is a better way. First, you probably want to buffer your output if you are going to write more than one time to the file, which will make writing to the file more efficient. In addition, when you buffer your output, you can use the newLine() method of the BufferedWriter object to insert a newline. The newline will be appropriate for the operating system that the program is running on. Here is an example:
File f = new File("C:/TestData/atest.txt");
BufferedWriter out = new BufferedWriter(new FileWriter(f) );
String fromString = "From: Jane";
out.write(fromString);
//Not written to the file until enough data accumulates.
//The data is stored in a buffer until then.
out.newLine();
String toString = "To: Dick";
out.write(toString);
out.newLine();
String dateString = "Sent: October 27, 2006";
out.write(dateString);
out.newLine();
out.close();
//Causes any unwritten data to be flushed from
//the buffer and written to the file.

How to read every line from a text file???

How can i read every line from my text file ("eka.txt")
now it only reads the first line and prints it out.
What is wrong with this?
import java.io.*;
import java.util.*;
class Testi{
     public static void main(String []args)throws IOException {
     BufferedReader stdin=new BufferedReader(new InputStreamReader(System.in));
File inputFile = new File ("eka.txt");
FileReader fis =new FileReader(inputFile);
BufferedReader bis = new BufferedReader(fis);
String test=bis.readLine();
String tmp= "";
while((bis.readLine().trim() != null)) {
int spacefound=0;
int l=test.indexOf(" ");
     for(int i=0;i<test.length();i++){
     char c=test.charAt(i);
     if(c!=' ') tmp+=""+c;
     if(c==' ' && (spacefound<1) && !(tmp.equals(""))){
     tmp+=""+c;
     spacefound++;
     if(tmp.length()==l) {
     System.out.println(tmp);
     tmp="";
     spacefound=0;
     if(tmp.length()<l){
     for(int i=0;i<=(l-tmp.length());i++)
     tmp+=""+' ';
     System.out.println(tmp);

Try this code, Hope it servers your purpose.

               while(st.hasMoreTokens())
                    System.out.println(st.nextToken());

Since the word "TEXT" is formed of 4 letters, you would read the text file 4 bytes by four bytes. Wrong on two counts. First, the file may not be encoded 1 byte per character. It could be utf-16 in which case it would be two byte per character. Second, even if it were 1 byte per character, the string "Text" may not start on a 4 byte boundary.
Consider a FileInputStream object "fis" that points to your text file. use fis.read(byte[] array, int offset, int len) to read every four bytes. Convert the "TEXT" String into a byte array "TEXT".getBytes(), and yous the Arrays class to compare the equality of the read bytes with your "TEXT".getBytes()Wrong since it relies on my second point and will fail when fis.read(byte[] array, int offset, int len) does not read 4 bytes (as is no guaranteed to). Check the Javadoc. Also, the file may not be encoded with the default character encoding.
The problem is easily solved by reading a line at a time using a BufferedReader wrapping an InputStreamReader wrapping a FileInputStream and specifying the correct character encoding.

Want to know how to check for new line character in text file

You are calling the readline() only once which means you are reading only the first line from the file...
Use a loop (Do-While preferably)
do{
//your code
}while(text == "")

af:validateLongRange displaying message: How to insert 'new line' ?

Hello,
While using <af:validateLongRange> tag we need to display message in a well formatted way, we have to display each statement in a new line.For eg. : message as displayed by property 'messageDetailNotInRange' must come in three different new lines not as a continuous statement.I tried inserting '\n' escape sequence for new line, but it dint work.I tried spacing the statements but that also is not working out.
Any idea how can we get this message displayed separately in three rows rather than in a continuous statement ?
++messageDetailNotInRange="You have entered a value more than is available. Value entered must be in the range of {2} to {3}.To delete this line, clear the value and click Delete"++
+<af:validateLongRange id="xyz_VC1" minimum="1"+
maximum="100"
messageDetailNotInRange="You have entered a value more than is available. Value entered must be in the range of {2} to {3}.To delete this line, clear the value and click Delete"
messageDetailMinimum="Minimum {0} allowed is {2}"
messageDetailMaximum="Maximum {0} allowed is {2}"
hintNotInRange="#{'xyz'}"/>

Thx..Done that!! but dint get the desired result ,I put it as :-
messageDetailNotInRange="You have entered a value more than is available.<br> Quantity entered must be in the range of {2} to {3}.<br> To delete this order line, clear the quantity and click DELETE."
On corresponding page this message was displayed as :
You have entered a value more than is available.<br> Quantity entered must be in the range of 1 to 100.<br> To delete this order line, clear the quantity and click DELETE.
It dint insert line breaks in the message.Do i need to write it differently?
Above html code is modified once i posted it, it has inserted line breaks here for the br tag i added , but in my actual .jsff page it did not . I can only see br tag displayed as part of message and no new line got inserted.
I dont see an option to attach a file with the post so that I can show the code to you.

ADF: how to insert new line character in column of VO?

Hi Everyone,
Im using Jdev 11G.
i have a VO with 5 columns displayed on the ADF page.(VO has total 8 columns)
1 column is the combination of 3 columns. i concatenated the 3 columns and added new line character after each column chr(13).
VO query is working very fine in Toad. the columnn displays each concatenated column value after a new line character but the same query is not working in ADF.
The column which is concatenating 3 columns and has to display with new line character is not displaying new line character its just concatenating the 3 values and displaying it on the page.
wat can be the solution for this in ADF?
Thank you.

Setting escape="false" will allow putting html <BR> in the column and it will display ok however if your table allows export to excel the <BR> gets exported and displays as text in your exported file. Also & will export as & To prevent that, use your original text without the escape=false setting and insert LF or CR (10 or 13 character), then add inline style of white-space: pre-line; to column or to style class in your skin. That will cause all line feeds to wrap but will export to excel without mixing html in the export.

How to insert new line in textarea

I try programatiaclly to add for example three strings in <textarea>
the final result should be something like this:
--TEXTAREA TAG BEGIN
line1
line2
line3
--TEXTAREA TAG END
I tried the hack described here;
http://www.mail-archive.com/[email protected]/msg08294.html
<c:set var="temp" value="one
two"/>
<c:set var="newline" value="${fn:substring(temp,4,5)}"/>after that I used it like this:
<textarea>
// forEach begin (write some output)
<c:out value="${newline}"></c:out> //try to add new line
// forEach end
</textarea>Sorry about the wrong comment style, I'm just pointing out whta I expect as a result.
I was surprised when I found out that "newline" value is "t" instead of special character "\n" or "\r". Anyway, I didn't receive the desired result.
I use XML JSP files and UTF-8.
Can anyone help me?

I think I remember using a pre tag in between.
<pre>
// ur text area tags here.
</pre>

Writing to a new line in a text files

I have a servlet that collects results from a questionnaire by getting the parameter values of the radio buttons on a questionnaire page. I am trying to store the results of the questionnaire by writing them to a text file. I can get it to write to the files fine but cannot seem to get it to write the next set of results to a new line. I have many different ways but cannot seem to get it to work. Any ideas?
Heres the part of the code that writes to a text file
String lineRead = "";
            int lineCount = 0;
            while((lineRead = input.readLine()) != null)
                lineCount ++;
                String result = request.getParameter("question" + lineCount);
                output.write(result + ",");
                output.write("\n");

Heres the part of the code that writes to a text
file
String lineRead = "";
int lineCount = 0;
while((lineRead = input.readLine()) !=
adLine()) != null)
lineCount ++;
String result =
String result = request.getParameter("question" +
lineCount);
output.write(result + ",");
output.write("\n");
Can you do output.writeln(result + ",");?
Failing that, putting output.write("\n") inside the while loop should do the trick.
