Java Programming

Hello guys,

I have a problem with this while loop to get it read every line in the text file. Now it read one and skips one,
basically reads odd lines, skips even ones. I want to read every line in the file.
I use it to insert data in a table in a database.

       FileInputStream fstream = new FileInputStream("nations.txt");
    // Get the object of DataInputStream
	DataInputStream in = new DataInputStream(fstream);
        BufferedReader br = new BufferedReader(new InputStreamReader(in));
        String strLine;

while ((strLine = br.readLine()) != null)   {
		String delimiter = ",";
      StringTokenizer st = new StringTokenizer(strLine,delimiter);			
		String code = st.nextToken();
		String name = st.nextToken();
				
		stmt.executeUpdate("INSERT INTO nat VALUES('"+ code +"'"+delimiter+"'"+ name +"')");		
       // read the next line
       strLine = br.readLine();					
    }
    //Close the input stream
    in.close();

Any help will be greatly appreciated.
Thank you in advance.
