How do you write to text files WITHOUT OVERWRITING?

[javajavalink]

I am relatively new to java and have already tried many ways to write
to text files with Java. Is there any way to write to a text file
without overwriting what is already there??

-You could append to the file, using something like:
BufferedWriter out = new BufferedWriter(new FileWriter("filename", true));

-You could look up RandomFileAccess
-You could read the file into a String, manipulate the string
and write it back out.

If you create a new instance of a FileReader with just the filename,
then that file will be erased if it is already there. You can use the
constructor of FileReader that accepts the filename and a boolean. If
the boolean is true, then the file will be appended.

None of the most used filesystems can insert data at a random place without
overwriting what is already there. So all operating systems and most
programming languages work in the same way. Databases use tree structures to
make it possible to insert data in the middle without overwriting anything.

Actually yes you can insert data at random places by utilizing the
RandomFile class. By supplying the length of each record, and the end
record number, you can reset the file size to the oldsize + newRec
length and boom you have an append. Also, you can write data into the
middle of a file without overwriting. All you have to do is create a
class that represents each row, read each record into the created
class, insert the new record at the appropriate point in the vector
during a For/While loop, and re-write the file using the data present
in the vector.

What "RandomFile" class? Do you mean java.io.RandomAccessFile? Then
you're wrong.

Nobody said anything about appending. That can be done.

middle of a file without overwriting.

No, you cannot.

All you have to do is create a
class that represents each row, read each record into the created
class, insert the new record at the appropriate point in the vector
during a For/While loop, and re-write the file using the data present
in the vector.

Please tell us that was a joke.
