Question

i have a text file with database table data in it and im trying to delete a part of the table. this is what is in the file:

name= john
name= bill
name= tom
name= bob
name= mike

here is my java code that compiles and runs, but the output is not what i expected and stuck.

import java.io.*;
public class FileUtil {

    public static void main(String args[]) {

        try {

            FileInputStream fStream = new FileInputStream("\\test.txt");
            BufferedReader in = new BufferedReader(new InputStreamReader(fStream));


            while (in.ready()) {
                //System.out.println(in.readLine());
                String line = in.readLine();
                String keyword = "name="; //keyword to delete in txt file
                String newLine=line.replaceAll(keyword,""); //delete lines that say name=
                BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream("testEdited.txt"));
                out.write(newLine.getBytes());
                out.close();

            }
            in.close();

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

    }
}

the output in the testEdited file is this:

mike

obviously i want to be left with just the 5 names. Can anyone help me out?
thanks

try this:

BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream("testEdited.txt",true));

true will append data to your file.
