Buffered Reader to display file content after calcuation

**jazz2k8** · May 9th, 2008, 07:42 AM

i am having data like this:Input say it as a.txt

S.No Description Qty. Units Rate (Rs.) Value (Rs.)
1 Aviation Lamp 1 Nos 3700 3,700
2 Lighting Arrester 1 Nos 1600 1,600
3 Aviataion Lamp Cable 31 Rmt 270 8,370

Gross Total 13,670
The above Total include Services Tax Amount of Rs 536
Total Invoice Value 13,670

i would like to get this data in the form of:Output should be

S.No 1
Description Aviation Lamp
Qty. 1
Units Nos
Rate (Rs.) 3700
Value (Rs.) 3700

S.No 2
Description Lighting Arrester
Qty.1
Units Nos
Rate (Rs.) 1600
Value (Rs.) 1600

S.No 3
Description Aviataion Lamp Cable
Qty.31
Units Nos Rmt
Rate (Rs.) 270
Value (Rs.) 8,370

Gross Total 13,670
Tax Amount of Rs 536
Total Invoice Value 13,670

--------------------------------

I tried with Buffered Reader, String Buffer used some regex code.but i am unable to get this..can any body help me in this..one more thing i want s to generate this should work dynamically...If we give any input .txt file the corresponding text should be convert into that format

**JavaPF** · May 9th, 2008, 08:02 AM

This will actually be quite complicated although I have a few ideas on how I would do it.

Will this file always be in this format/order?

Let me know and I will write some code for you..

**jazz2k8** · May 11th, 2008, 11:34 PM

Thanks for your reply...

S.No Description Qty. Units Rate (Rs.) Value (Rs.) these fields must be same for every invoice..but the particulars may vary...i have written code like this:

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Sampleexpense {

private int i;

public static void main(String args[]) throws FileNotFoundException, IOException {
int i;
String[] substr;
String sub = null;
String res = null;
BufferedReader in = new BufferedReader(new FileReader("C:\\Documents and Settings\\abb\\Desktop\\test\\Invo.txt"));
StringBuffer sb = new StringBuffer();
String line;
line = in.readLine();

while (line != null) {
sb = sb.append(line);
line = in.readLine();
}

String line1 = sb.toString();
//System.out.println(line1);
sub = line1.substring(line1.indexOf("Value (Rs.)"), line1.indexOf("Gross Total"));

sub = sub.replace("Value (Rs.)", "");
// System.out.println("Sub String " + sub);
res = sub;
Matcher tabledata = Pattern.compile(("\\d*,\\d{3}"), Pattern.CASE_INSENSITIVE).matcher(sub);
i = 0;
while (tabledata.find()) {

i++;
}

String[] table = new String[i];
Matcher tdata = Pattern.compile(("\\d*,\\d{3}"), Pattern.CASE_INSENSITIVE).matcher(sub);
for (int ij = 0; ij < i; ij++) {
while (tdata.find()) {
table[ij] = tdata.group();

break;
}

}
String[] res1 = new String[i];
for (int ik = 0; ik < i; ik++) {
//System.out.println(" output " + table[ik]);
res1[ik] = String.valueOf(ik + 1);
}

for (int a = 0; a < i; a++) {

//System.out.println("Number "+(a+1)+" "+table[a]);

sub = sub.substring(sub.indexOf(res1[a]), sub.indexOf(table[a]));

System.out.println(" " + sub + table[a]);

res = res.replace(sub + table[a], "");
sub = res;

}
}
}

Output:
1 Aviation Lamp 1 Nos 3700 3,700
2 Lighting Arrester 1 Nos 1600 1,600
3 Aviataion Lamp Cable 31 Rmt 270 8,370

Can you simplify it!!!????

**jazz2k8** · May 12th, 2008, 07:55 AM

Here i tried with some other code also:

But giving some errors:

Please have a look:

public class TabData2 {

static String Sno,Qty,Description,Unit,Rate,Value;
public static void main(String args[]) throws FileNotFoundException{
File file = new File("D:\\bharath\\CSV\\tab2.txt");
StringBuilder sb = new StringBuilder();
Scanner scanner = new Scanner(file);
while (scanner.hasNextLine()) {
// String line = scanner.nextLine();
// while(scanner.hasNext()){
Sno = scanner.next();
Description = scanner.next();
Qty = scanner.next();
Unit = scanner.next();
Rate = scanner.next();
Value = scanner.next();
Formatter fmt=new Formatter();
fmt.format("%s\n",Sno);
fmt.format("%s\n",Description);
fmt.format("%s\n",Qty);
fmt.format("%s\n",Rate);
fmt.format("%s\n",Value);
// fmt.format("%5$2S,%4$2s,%3$2s,%2$2s,%1$2s" );

System.out.println(Sno);
System.out.println(Description);
System.out.println(Qty);
System.out.println(Rate);
System.out.println(Value);

}

}
}

Output:

..I can understand the Exception The given file has 47 elements. Each time i am reading bundle of 6 elements. So what happened is, in last read i have only 5 elements. No 6th element.

so..got an exception...

can u look these two let me know the status ...thanks

**JavaPF** · May 12th, 2008, 08:04 AM

I'm not too sure if that code is the best way to do it..

I'm currently working on solving this problem for you so ill post back as soon as its done!

Brilliant news!! Glad I could help

I am looking to add a 'Mark Thread as Solved feature', but for now, could you please edit the thread title and add [SOLVED] infront of 'How to achieve this?'

Thank you.

**jazz2k8** · May 13th, 2008, 06:40 AM

How to edit the title?

**JavaPF** · May 13th, 2008, 06:45 AM

There is no option to mark thread as solved in the Thread tools currently on these forums. I am looking to add the plugin to do it ASAP.

For now, can you please manually do it. Just click the 'Edit' button to edit the thread and add [SOLVED] to the front of the title.

I will have a go at this for you but the last bit of code I did for you took me days to work out. This really is very complicated!!

Are you also able to generate this output as a .csv file?

If the output is comma seperated, it would be easier to work with.

**jazz2k8** · May 13th, 2008, 07:07 AM

i never checked with csv...here i attached that one also..can u have a look at this..this looks very strange...if you are comfort with csv its not a big issue for me...

I know it is very complicated issue but...

your help is awesome...

thanks for your time and support...

Well to get the pervious extracted information along side this new input would mean that I would have to completely re-write the previous code. This is a very, very complicated task!! It may even be above my skill level.

I simply do not have the time to do all of this for you. I suggest you try to write this yourself and I will try to help you as you get stuck.

The good thing about using a csv file is that you can use the "," as a delimiter which should help you to manipulate the data.

Have you thought about contracting someone to do this work for you?
