Problem in deleting and renaming?

Question

i have a text file in which i have to change some values in it.
so i tried using this code..
asciiFile = new File(FileName);
            TempFile = new File(asciiFile.getParent(), "Temp1.xml");
            BufferedReader buff = new BufferedReader(new FileReader(asciiFile));
            BufferedWriter bw = new BufferedWriter(new FileWriter(TempFile));
            for(String line = ""; (line = buff.readLine()) != null;)
                if(line.contains("<equation format=\"inline\">"))
                    for(int vv = 0; vv < ActualEquationToBePasted.size(); vv++)
                        String ff = line.replace(EquationToBeExceuted.elementAt(vv).toString(), ActualEquationToBePasted.elementAt(vv).toString());
                        line = ff;
                    bw.write(line);
                    bw.write("\n");
                  //  System.out.println(line);
                } else
                    bw.write(line);
                    bw.write("\n");
                  //  System.out.println(line);
            buff.close();
            bw.close();
           File org = new File(FileName);
         System.out.println(asciiFile.delete());

Answer 1

works here...
import java.io.*;
public class FileDelRen {
       public static void main(String[] xyz){
              String fName = "file1.txt";
              String tName = "temp.tmp";
              File file = new File(fName);
              File temp = new File(file.getParent(),tName);
              try{
                  BufferedReader br = new BufferedReader(new FileReader(file));
                  BufferedWriter bw = new BufferedWriter(new FileWriter(temp));
                  String data = null;
                  while( (data = br.readLine()) != null ){
                     bw.write(data,0,data.length());
                  br.close();
                  bw.close();
                  br = null;
                  bw = null;
                  file.delete();
                  System.out.println( " File renamed : " + temp.renameTo(file));
              }catch(FileNotFoundException fnfe){
                                 fnfe.printStackTrace();
              }catch(IOException ioe){
                                 ioe.printStackTrace();
}btw, i added the br = null; and bw = null; to ensure there are not references to the File objects in question...
