Files writing to it again{resolved}

[jframe]

i have created a small three field form, and can save the data into a file using writeUTF, but once the program is closed, and then opened again and i write new data, the prev values of the file are washed?
i understand i need to append, but how?
thanks

try this:
FileOutputStream(File filename, boolean append)
if append is true, then it will write and the end of file, else overwrite.

Sincerely,
Neptune.

If you would like to keep the path platform independent then you can use the following as an example.

FileWriter fw = new FileWriter("C:" + File.separator + "Java" + File.separator + "MyFiles" + File.separator +"Text.txt",true);

Also the only constructors that allows you the ability to append data to a file is FileWriter(String file, boolean append) and FileOutputStream(String file, boolean append). I don't know why Sun didnt add this functionality to the other constructors that allow you to pass in File objects.

Look at the previous code.

[jframe]

FileOutputStream(somefile.dat, true)
rite?

[Dillinger4]

FileOutputStream fout = new FileOutputStream("C:" + File.separator "somefile.dat", true);

[jframe]

this is what i didnow


// File data = new File("somefile.dat"); //commented this out

and made this:..its working now

ostream = new DataOutputStream(
new BufferedOutputStream(
new FileOutputStream("somefile.dat",true)));
