My FileWriter file is completely empty

Question

Just for your info: I had another question relating to this code, and I had already asked it, I edited the question to this question (completely) but I got no responses.

AIM: I am trying to read in a file(.txt containing HTML) and sort the content. It does create a text file and it completely empty. I read some similar situations but I have seen their mistake was not adding a out.flush() or out.close() file.

Here is the code till now:

import java.io.*;


public class File { 

    public static void main(String[] args) throws IOException {
        try {
            String input = "SCCM.txt";
            BufferedReader in = new BufferedReader(new FileReader(input));
            String output = "output.txt";
            BufferedWriter out = new BufferedWriter( new FileWriter( output ) );

            String inputLine = "", s="windows";
            String regex = "&nbsp";
            while ((inputLine = in.readLine()) != null) {
                if ( inputLine.contains(s) ) {
                    inputLine.split(regex);
                    out.append( inputLine );
                    out.newLine( );
                }
                in.close();
                out.flush();
                out.close();
            }
        }
        catch(IOException e) {
            System.out.println("Hi");
        }
    }
}

Content I want to sort :

<TR class="RowDark">
    <TD width=0><A href="Report.asp?ReportID=100&amp;sp=Service+Pack+1&amp;os=Microsoft%28R%29+Windows%28R%29+Server+2003%2C+Enterprise+Edition"><IMG border=0 src="images/icolink3.gif" alt="Open the target" width=11 height=11></A></TD>
    <TD class=SimpleTextSmall>&nbsp;Microsoft(R)&nbspWindows(R)&nbspServer&nbsp2003,&nbspEnterprise&nbspEdition&nbsp;</TD>
    <TD class=SimpleTextSmall>&nbsp;Service&nbspPack&nbsp1&nbsp;</TD>
    <TD class=SimpleTextSmall>&nbsp;60&nbsp;</TD>
</TR>

Output I want: Microsoft (R) Windows (R) Server 2003 , Enterprise Edition , Service Pack 1 , 60

Stuff I read (for your information): Java txt File from FileWriter is empty

UPDATE:

import java.io.*;

public class File {

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

    String input = "SCCM.txt";
    BufferedReader in = new BufferedReader(new FileReader(input));
    String output = "output.txt";
    BufferedWriter out = new BufferedWriter( new FileWriter( output ) );


    try {

        String inputLine = "", s="Windows";
        String regex = "&nbsp";
        while ((inputLine = in.readLine()) != null) {
            if ( inputLine.contains(s) ) {
                inputLine.split(regex);
                out.write(inputLine);
                out.newLine( );
            }

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

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

}

UPDATE:

The file DOES output (tons of love to those who helped)

Here is how it is

 <TD width=0><A href="Report.asp?ReportID=100&amp;sp=Service+Pack+1&amp;os=Microsoft%28R%29+Windows%28R%29+Server+2003%2C+Enterprise+Edition"><IMG border=0 src="images/icolink3.gif" alt="Open the target" width=11 height=11></A></TD>
            <TD class=SimpleTextSmall>&nbsp;Microsoft(R)&nbspWindows(R)&nbspServer&nbsp2003,&nbspEnterprise&nbspEdition&nbsp;</TD>

Any hints/tips/tricks to perhaps make it readable?

Answer 1

You are closing the output stream inside the while loop so an IOException is thrown almost immediately but the details of the exception are not displayed. These statements

in.close();
out.flush();
out.close();

should be in a finally block

try {
   ...
catch (IOException e) {
    e.printStackTrace(); // add me
} finally {
    in.close();
    out.flush();
    out.close();
}

Only then can you check for the String Windows (as mentioned in the comments)

String s = "Windows";

Answer 2

inputLine never contains windows however it does contain Windows, which causes the the conditional to always evaluate to false, preventing the append method from being called.

Change the following line:

String inputLine = "", s="windows";

to

String inputLine = "", s="Windows";

or lowercase s before the comparison:
