How to write after a line in a text file

i need to write a string into a text file, after a particular line that i need to search.
The line to serch and the line to write are two String types.
String line_to_search="<first";
String line_to_write="<second>";

I found a way to make that but now i have another problem, the system write the String in the file but with a space. In particular in the code a want to write the string in the third line
The code is
<%@ page import="java.io.*" %>
<%
String value ="Anthony";
RandomAccessFile file = null;
file = new RandomAccessFile ("G:\\rrr.txt", "rw");
String aaa=file.readLine();
String aaa2=file.readLine();
file.writeChars(value);
%>
The rrr file is before:
Hello
my name is
and after the rr file is
Hello
my name is
A n t h o n y

That is not my problem . i already read it char by char.. i am getting complete line..But this process is taking to much time..So thats why i directly wanna read complete line or word to save time..

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

Hi All,
I`m trying to read data from text file. However I`m not sure whether the data is in 1st line or nth line. Now I`m trying to read the text from the readline. But if text is "" and not NULL then my code fails. So I want to know how to check for new line character and go to next line to find the data. Please help.
Thanks

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 == "")

How to read the last line in a text file using text_io?? please help

Dear all
I made a procedure that append text into a text file on the operating system.
the text file grows rapidly. It contains now about 200,000 line . I need to read the last line only . In other wprds i need to go direct to the last line to read some values. Is it possible??
Please help

Hello,
If you know the number of the line you want to read, I can sugget you to use the MORE dos command or the TAIL unix command that redirect to a temporary text file
Example to create a file that contains the 200010th last lines :
(Client)Host( 'MORE the_file_name.txt +200010 > small_file.txt') ;So you have only to read the small file with the TEXT_IO functions.

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?

Thank for reply=D
Yap the row and column will change but i had already parse these lines into my code. However, i am still figuring on how to get the integer number 1,2,2,4 of the text file using while loop and not include the "</matrix>" in the reading. Can this be done?If the numbers you want are at fixed byte positions in the file that are known ahead of time, you can use java.io.RandomAccessFile to skip to those positions. However, that seems unlikely.
If, as is the more likely case, those are not at fixed positions, you'll have to read everything preceding them. (Note that this is not a Java issue. This is how file I/O works.) You'll need to ignore the lines that are meaningless to you (read those lines and do nothing with them) figure out, by whatever rules you have--line numbers, preceding tokens, whatever--when you're at the lines you do care about, and then read and process those lines accordingly.

File adapter-How to set line break in text file-split record into two lines

Dear Guru's,
I have to solve following problem with XML (with mulitiple records) to TEXT file scenario using file adapter. I have to output for ever ONE data record in XML always two identical lines in text file. Second line should have a little bit different mapping in few fields like date,... So I did duplicate fileds in my output structure in mapping and need to know how to set line break in the middle and see half of structure in first line and next structure half in second line
My output structure in mapping is:
CASHFLOW
- INTERFACE
- GESELLSCHAFT
- ANWENDUNG
- PRODUKT
- VERTRAG
- BETRAG
- WAEHRUNG
- DIRECTION
- BEWEGUNGSTYP
- FAELLIGKEIT
- ZINSFESTSTELLUNG
- ZAHLUNGSTAG
- RENDITE
- INTERFACE2
- GESELLSCHAFT2
- ANWENDUNG2
- PRODUKT2
- VERTRAG2
- BETRAG2
- WAEHRUNG2
- DIRECTION2
- BEWEGUNGSTYP2
- FAELLIGKEIT2
- ZINSFESTSTELLUNG2
- ZAHLUNGSTAG2
- RENDITE2
Question is how can I set on receiving file adapter in Content Conversion Parameters that fields from first structure half INTERFACE...RENDITE should be outputed in one line and fields from second half of structure INTERFACE2...RENDITE2 should start on second line in final text file.
I'm getting at the moment one line only and I need to know how can set line break so that second line starting with INTERFACE2(CA)...RENDITE2 will start in new line.
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",2,12,2009-01-28,2009-01-27,2009-01-28,"0.0000000",CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",1,10,2009-01-27,2009-01-27,2009-01-27,"0.0000000"
This should be final output:
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",2,12,2009-01-28,2009-01-27,2009-01-28,"0.0000000"
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",1,10,2009-01-27,2009-01-27,2009-01-27,"0.0000000"
My file adapter settings:
RecordsetStructure=CASHFLOW
CASHFLOW.fieldNames=INTERFACE,GESELLSCHAFT,ANWENDUNG,PRODUKT,VERTRAG,BETRAG,WAEHRUNG,DIRECTION,BEWEGUNGSTYP,FAELLIGKEIT,ZINSFESTSTELLUNG,ZAHLUNGSTAG,RENDITE
CASHFLOW.fieldSeparator=,
CASHFLOW.endSeparator='nl'
CASHFLOW.fieldNames=INTERFACE2,GESELLSCHAFT2,ANWENDUNG2,PRODUKT2,VERTRAG2,BETRAG2,WAEHRUNG2,DIRECTION2,BEWEGUNGSTYP2,FAELLIGKEIT2,ZINSFESTSTELLUNG2,ZAHLUNGSTAG2,RENDITE2
CASHFLOW.fieldSeparator=,
It wont help if I add two identical structures in mapping because in output i would see for multiple entries section with first lines only and after that section with second lines only. And CASHFLOW is one part of more complex mapping ...
(This is final output structure RecordsetStructure=HEADER,CASHFLOW,CONDITION,REFERENCE,CONTRACT - more sections with different data and all these should have duplicate lines at the end)
Thanks a lot for any help
Cheers
Marian

Hi Ivan,
right, I did test just for sure.
Putting constant 'nl' into field CASHFLOW-INTERFACE1 didnt help - still getting one line instead two lines.
CA ,"0100" ,"7" ,"512" ,20090127GTP101 ,-12454762586.6800 ,"EUR" ,2 ,12 ,2009-01-28 ,2009-01-27 ,2009-01-28 ,"0.0000000" ,'nl' ,"GTP1" ,"7" ,"512" ,20090127GTP101 ,-12454762586.6800 ,"EUR" ,1 ,10 ,2009-01-27 ,2009-01-27 ,2009-01-27 ,"0.0000000"
So there is still question. Is there any way (mapping,...) how to output always 2 lines in text file for one record in XML. It always does 1 record in mapping structure = 1 line but we need 2 lines ...
Example:
Input: 4 records in XML
Output: 8 lines in final text file ...
Thanks to you all guys

How to insert new line in a text file

hi all,
i wnat to know how can i insert a new line in a text file using java.
for example i want the formate of the text like this
1 2 3
4 5 6
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();
}

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.

How to write a code for open new txt file in swing

hai all,
now i do one project in java.that project's GUI is Swing. But i don't known swing (basic).So how to write a code for open new txt file and "Open window " in menu item on swing.that means when i click the "New" on menu that time open a new txt file. open also like that type.

Swing Tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/index.html
Since you don't know the basic of swing read the tutorial, it is for your own good because it is useless if we provide you with a code you don't even understand and how it works.
If you want a menu read the tutorial about using menus and for opening a file read using JFileChooser.
note: don't use the word urgent because it implies that your problem is more important than others.

How to only read the last line in the text file by using BufferedReader ?

Dear all,
Hello, I am new to Java. Do anybody know how to read the last line (this is the last record) in the text file.The method I am now using is reading from the first line until I reach the last line in the text file. Thank you!!
BufferedReader br = new BufferedReader(new FileReader("c:\\sdk1.4.1\\bin\\dbExport.txt"));
DataInputStream in = new DataInputStream(new FileInputStream("c:\\sdk1.4.1\\bin\\dbExport.txt"));
String input;
String firstinput;
String secondinput;
int count=90;
int year=1955;
while ((input = br.readLine()) != null) {
firstinput = input.substring(0, 10);
secondinput = input.substring(10);
String insertStore1 = ("INSERT INTO AUTHORS " +
"VALUES ('" + count + "', '" + firstinput + "', '" + secondinput + "', 1955)");
System.out.println(insertStore1);
int result = stmt.executeUpdate(insertStore1);

I suppose you could use a java.io.RandomAccessFile.

SQL>I couldn't quite figure out the "9" and the "99" data that was on those lines so I assume it should just be ignored. I also formatted the report data to fixed columns width in my external text file as I'd assume that's how the data would be generated, not that that would make much difference when extracting the values with regular expressions as I've done.
So... something like that anyway. ;)

How to write the JTables Content into the CSV File.

Hi Friends
I managed to write the Database records into the CSV Files. Now i would like to add the JTables contend into the CSV Files.
I just add the Code which Used to write the Database records into the CSV Files.
void exportApi()throws Exception
          try
               PrintWriter writing= new PrintWriter(new FileWriter("Report.csv"));
               System.out.println("Connected");
               stexport=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
               rsexport=stexport.executeQuery("Select * from IssuedBook ");
               ResultSetMetaData md = rsexport.getMetaData();
               int columns = md.getColumnCount();
               String fieldNames[]={"No","Name","Author","Date","Id","Issued","Return"};
               //write fields names
               String rec = "";
               for (int i=0; i < fieldNames.length; i++)
                    rec +='\"'+fieldNames[i]+'\"';
                    rec+=",";
               if (rec.endsWith(",")) rec=rec.substring(0, (rec.length()-1));
               writing.println(rec);
               //write values from result set to file
                rsexport.beforeFirst();
               while(rsexport.next())
                    rec = "";
                     for (int i=1; i < (columns+1); i++)
                         try
                                rec +="\""+rsexport.getString(i)+"\",";
                                rec +="\""+rsexport.getInt(i)+"\",";
                         catch(SQLException sqle)
                              // I would add this System.out.println("Exception in retrieval in for loop:\n"+sqle);
                     if (rec.endsWith(",")) rec=rec.substring(0,(rec.length()-1));
                    writing.println(rec);
               writing.close();
     }With this Same code how to Write the JTable content into the CSV Files.
Please tell me how to implement this.
Thank you for your Service

Hi Friends
I just modified my code and tried according to your suggestion. But here it does not print the records inside CSV File. But when i use ResultSet it prints the Records inside the CSV. Now i want to Display only the JTable content.
I am posting my code here. Please run this code and find the Report.csv file in your current Directory. and please help me to come out of this Problem.
