hi
I am having the file like mentioned above.i want to print TER till END and save it another file. import java.lang.*;
import java.util.*;
import java.text.*;
import java.io.*;
public class tt {
public static void main(String[] args) throws IOException
{
File inputFile = new File("1AB4.rtf");
FileReader in = new FileReader(inputFile);
File outputFile=new File("t.rtf");
FileWriter out=new FileWriter(outputFile);
int end;
String s;
boolean stop=false;
BufferedReader br=new BufferedReader(in);
PrintWriter pw=new PrintWriter(out);
while((s=br.readLine())!=null)
{
stop = s.startsWith("END");
if (!stop)

System.out.println(s);
else
{

end=s.indexOf("TER");
s=s.substring (end,s.indexOf("END"));

System.out.println(s);

break;
}

pw.write(s);

}

in.close();
out.close();
}
}
This is not giving the output of what i am expecting.
TIA

while((s=br.readLine())!=null)
{
stop = s.startsWith("END");
if (!stop)

System.out.println(s); /// <<<<<<<<<<< This one prints *each* line
else
{

end=s.indexOf("TER");
s=s.substring (end,s.indexOf("END"));

System.out.println(s);

break;
}

Is this what you want?

while((s=br.readLine())!=null) {
boolean busy = false;
stop = s.startsWith("END");
if (stop) {
System.out.println(s); // comment out if you don't want the END to be printed out
break;
}
else
{
busy = busy || s.indexOf("TER");
if (!busy)
continue;
System.out.println(s);
}
}

hi zzynx
i've tried your code.but ther entire file is printing.

Sure you copied/pasted it correctly?
I don't think so. For me it's working perfectly.
The printing output as well as the t.rtf output file both look as my previous comment.

**Can you make sure to copy/paste and try it once again, please.**

ASKER

I have done it once again.. but i am getting entire file.
as per your code

stop = s.startsWith("END");
if (stop) {
pw.println(s);
}
prints the whole sequence..isn't it..
it would be better if u explain me how it works.. .

Can't believe my eyes/ears.

>> it would be better if u explain me how it works..
OK, here we go. See the comments I added.

public class tt {
public static void main(String[] args) throws IOException
{
File inputFile = new File("c:\\In.rtf");
FileReader in = new FileReader(inputFile);
File outputFile=new File("c:\\Out.rtf");
FileWriter out=new FileWriter(outputFile);
int end;
String s;
boolean stop=false;
BufferedReader br=new BufferedReader(in);
PrintWriter pw=new PrintWriter(out);
boolean busy = false; // have we found the line with "TER" yet?
while((s=br.readLine())!=null) // read line by line
{
stop = s.startsWith("END"); // search for the line starting with "END" == the last line
if (stop) { // the last line found
pw.println(s); // write to file that last line
System.out.println(s); // print out that last line
break; // we're done processing the input file
}
else // we're not at the last line yet
{
busy = busy || (s.indexOf("TER")!=-1); // Is this line the one that contains "TER"?
if (busy) { // Is the line with "TER" already found?
System.out.println(s); // then print out this line (=one that comes after the line with "TER")
pw.println(s); // write this line to the output file
}
}
}

in.close();
out.close();
}
}

So as long as the line containting "TER" isn't encountered, nothing is printed.
I hope it is clear now.

Well, maybe if kousis can post the entire code that he is using, we could be able to help out better (there might be something different from the code that zzynx posted, I guess).

ASKER

thanx for your explanation. zzynx I am using the same code as zzynx mentioned. but i am getting the different output. i am confused how output changes with the same program.
regards
kousis

My input file is what I copied from your question (everything except the []):

ASKER

sorry ..my output is the same as my input

Perhaps there is something wrong with the logic of 'stop' that you're implementing. Can you post the code too, anyway?

Unbelievable!

Can you please alter the two

System.out.println(s);

into once

System.out.println("**** "+ s);

and once

System.out.println("==== "+ s);

What is your output then?
This is to see which one is responsible for the printing of the lines we don't want to be printed.

ASKER

while((s=br.readLine())!=null)
{
stop=s.startsWith("END");
if (stop) {
pw.println(s);
System.out.println("****"+s);
break;
}
else
{
busy = busy || (s.indexOf("TER")!=-1);
if (busy) {
System.out.println("-----"+s);
pw.println(s);
}
}
}
i am getting the output of entire file with
------HETATM
-------HTATM and ends with
****END

Well, I know that zzynx can't believe it. Neither can I.

Maybe you could try:

stop = s.startsWith ( "END" ) ;
System.out.println ( s + " CONTAINS END: " + stop ) ;

-> just see the value that it prints.

I suggest the use of:

while ( ( s = br.readLine () ) != null )
{
if ( s.indexOf ( "END" ) == 0 )
{
....

Important:

And you do have

boolean busy = false;

before the while loop?

Can you check in your code if you have a System.out.println ( s ) ; statement somewhere inside the while loop but outside the if/ else cases, by mistake?

Then, how does it come that when performing

busy = busy || (s.indexOf("TER")!=-1);

busy turns to true for e.g. the first line...

>> Can you check in your code
We can keep busy like this...
I posted the whole class tt, let him post it too.

ASKER

it prints the entire file and also prints
contains end:true at the end.

Or try this:

int start = -1 ;

while ( ( s = br.readLine () ) != null )
{
if ( s.startsWith ( "END" ) )
{
pw.println ( s ) ;
break ;

} // end if

start = ( start >= 0 ) ? start : s.startsWith ( "TER" ) ;

if ( start >= 0 )
pw.println ( s ) ; // end if

} // end while

Can you post the output of this code (added some extra tracing):

public class tt {
public static void main(String[] args) throws IOException
{
File inputFile = new File("c:\\In.rtf");
FileReader in = new FileReader(inputFile);
File outputFile=new File("c:\\Out.rtf");
FileWriter out=new FileWriter(outputFile);
int end;
String s;
boolean stop=false;
BufferedReader br=new BufferedReader(in);
PrintWriter pw=new PrintWriter(out);
boolean busy = false; // have we found the line with "TER" yet?
while((s=br.readLine())!=null) // read line by line
{
stop = s.startsWith("END"); // search for the line starting with "END" == the last line
System.out.println("ReadLine: <"+ s + "> stop= "+ stop); // <<<<<<<< EXTRA Tracing >>>>>>>>>>
if (stop) { // the last line found
pw.println(s); // write to file that last line
System.out.println(s); // print out that last line
break; // we're done processing the input file
}
else // we're not at the last line yet
{
System.out.println("[1] busy = " + busy); // <<<<<<<< EXTRA Tracing >>>>>>>>>>
busy = busy || (s.indexOf("TER")!=-1); // Is this line the one that contains "TER"?
System.out.println("[2] busy = " + busy); // <<<<<<<< EXTRA Tracing >>>>>>>>>>
if (busy) { // Is the line with "TER" already found?
System.out.println(s); // then print out this line (=one that comes after the line with "TER")
pw.println(s); // write this line to the output file
}
}
}

in.close();
out.close();
}
}

Another point I was thinking of...
Are you sure you run the code you think you are running?
In other words make sure that the class file you are running corresponds with the code we see here.
(Delete your class file and recompile/rebuild.
Or rename your class from "tt" to "ZzynxDemo" ;)
Just a thought...

Hmmm.... you can try that. You can also try the code which I posted in my last comment and let me know if it worked.

Now that you're online...
What about this question?

If mayankeagle agrees, I think I got the right answer.
So my recomm: no split.
What do you think mayankeagle?

Hmmm. You've put me into thought. I wouldn't mind it, zzynxie, but my comment at https://www.experts-exchange.com/questions/20946380/print-page-from-desired-position.html#10782194 could also be a correct solution. If you had posted your comment at {http:#10782400} before that one, I would've agreed.

My third comment was a working (and tested) one.

I know, zzynx. I have no doubts that it will not work. But the comment I posted at {http:#10782194} would also work. Just that I did not provide full-code but only the main loop.

>> I have no doubts that it will not work

I have no doubts that it will work ;-)

You just said:
>> If you had posted your comment at {http:#10782400} before that one, I would've agreed.
Well, my *third* comment is posted long before that one

Date: 04/07/2004 03:24PM CEST
and
Date: 04/08/2004 01:13PM CEST

Ah, I didn't notice that was your third comment. I thought you were referring to the one which Venabili mentioned, at: {http:#10782400}

Ok, I agree.

Thanks.
How do I get the reference (like {http:#10782400} ) to my third comment?

You can't. Page editors and moderators have a different view where they can see the comment-IDs, but we can't see it in our view. THe only time we can capture the comment ID of a comment is perhaps when we get a mail-alert for that one (because the link there comes along with the comment-ID), like: http://www...../..../Java/Q_20946380.html#11047744

I see. Never mind.

So,

dear moderator,
the recommandation we both agreed upon is

Accept: zzynx (third comment on this Q)

What would EE-life be easy if all authors closed their Q's...
