hi,

im new in computing....that's why i think java programming is too difficult
to me....
recently, i've been trying to convert one data file to another formated file...

the contents of the file data1.dat is in the following:

01, 647394,06/03/01,0748,0,06/03/2001
01, 642924,06/03/01,0748,0,06/03/2001
01, 642924,06/03/01,0748,0,06/03/2001



-------------
i would like to convert the data of the above file to another formated file
data2.dat and the contents looks like:

"001:647394:010306:074800"
"001:642924:010306:074800"
"001:642924:010306:074800"



do u know how to solve the above problem, please help
thanks
leo

here is my source code...that's what i have done so far:

import java.awt.*;
import java.io.*;

public class StreamTokenizerTest extends Frame {
public static void main(String args[]) {
StreamTokenizerTest test=new StreamTokenizerTest();
TextArea ta=new TextArea();

try {
StreamTokenizer stoken=new StreamTokenizer(new FileReader ("trans.dat"));
stoken.eolIsSignificant(true);
stoken.parseNumbers();
stoken.quoteChar('\"');
stoken.slashSlashComments(true);
stoken.slashStarComments(true);
while (true) {
stoken.nextToken();
if (stoken.ttype==StreamTokenizer.TT_EOF)
break;
else if (stoken.ttype==StreamTokenizer.TT_EOL)
ta.append("sss" + stoken.lineno()+"line\n");
else if (stoken.ttype==StreamTokenizer.TT_NUMBER)
ta.append("Number:"+stoken.nval+":");
else if (stoken.ttype==StreamTokenizer.TT_WORD)
ta.append("String:"+stoken.sval+"\n");
else if (stoken.sval!=null)
ta.append("other:"+stoken.sval+"\n");
}
}
catch (FileNotFoundException e) {
System.out.println("File not Found.");
System.exit(0);
}

catch (IOException e) {
System.out.println("IOException");
}

test.add(ta,BorderLayout.CENTER);
test.setSize(300,300);
test.setVisible(true);
}
}
