creating and writing to a file on internal storage

I would like to create a file in android tablet and write some data to开发者_运维百科 it. (only a few kilobytes).

The link below has the code i tried, but i dont see the file that got created in /data directory. some one said i have to root my device for seeing those files.

Question: I want to create and write to a file using the internal storage without rooting the device . Is it possible ?

I'm posting this question as i couldn't find answers for

Cant find the file i created on android tablet

Use openFileOutput() to create a file:

FileOutputStream f = openFileOutput("filename", Context.MODE_PRIVATE);
//write to the file stream
f.close();

That would normally create a file within internal storage that would be only accessible by your app.
