Thread: Split the file based on the on comparison between line being read from Fil and a constant string.

Hi,

I have a large file containing records as below :-


ACCT_NO||ACC_NAME||ADDR||PHONE
----------------------------------
1 abcv adfe 345
2 erfr ertt 2345
3 efrtt fkgfdk 23454


ACCT_NO||ACC_NAME||ADDR||PHONE
-----------------------------------
1 abcv adfe 345
2 erfr ertt 2345
3 efrtt fkgfdk 23454

the requirement is to read the file and spilt the large file into chunks when it encounter "ACCT_NO||ACC_NAME||ADDR||PHONE"

Thanks in adv!

I have the below code which works fine for just splitting the file according to the size specified.

package readstring;

import java.io.BufferedInputStream;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.FileReader;

import java.io.IOException;



public class readstring {

public static void splitFile(File f) throws IOException {

BufferedInputStream bis = new BufferedInputStream(

new FileInputStream(f));

FileOutputStream out;



String name = f.getName();

int Counter = 1;

int sizeOfFiles = 1024 * 1024;// 1MB

byte[] buffer = new byte[sizeOfFiles];

int tmp = 0;

while ((tmp = bis.read(buffer)) > 0) {

File newFile=new File(f.getParent()+Counter+name);

newFile.createNewFile();

out = new FileOutputStream(newFile);

out.write(buffer,0,tmp);

out.close();

}

}

public static void main(String[] args) throws IOException {

splitFile(new File("D:\\My.txt"));

}

}

But i want to split the file whenever it encounters the line
"ACCT_NO||ACC_NAME||ADDR||PHONE"..

Not able to compare this string with the input being read from file and split the file based on this..

I want to know how exactly i can do it..

Kindly suggest..
