What have you tried?

Richard MacCutchan 11-Oct-11 5:40am

You will need to read the file one record at a time and ignore all records until you see the word "SUCCESS".

Do you know how to read a file? If not, take a look at this tutorial.

udayz999 11-Oct-11 6:05am

ss,i know it

Richard MacCutchan 11-Oct-11 6:23am

So what exactly is your difficulty? Please edit your question and explain what problem you have in reading the file and recognising the word "SUCCESS", or any other keyword you may choose.

i m not getting how to skip the values upto SUCCESS word,i want to print values after SUCCESS only

Richard MacCutchan 11-Oct-11 6:55am

Set a flag to FALSE
Read next line
If flag == TRUE then print line
if line == SUCCESS then set flag = TRUE
Repeat

Easy?

I've started it for you, I'll leave you to fill in the blanks:

Java

public class FileSpliter {
    
    public static void main(String[] args) {
        // open the input file
        
        // read until the line is SUCCESS
        
        // open output file

        // read remainder of file and write to output file
        
        // close output file
        
        // close input file
    }
}

Solution 2

hi
you can read the input file line by line, find desired pattern, and finally write the desired lines to output file.
This example could help you:

ok, without giving away too much and a much simpler approach instead of reading line by line, although may need optimisation when u have had a hang of it:

1) open the input file
2) read into a

Java

char[]

of appropriate size
3) convert to string
4) look for "SUCCESS"
5) and, read everything after that keyword
6) finally, write to the output file. DONE!!!
