10. Can I write in MS Word File from FileOutputStream Constructor coderanch.com

hi, you can read and write to a .doc file like any other file. but the text that appears in ms-word is not just clear-text in the .doc file. it is embeded in formating (color/font/size..) stuff. so you first need to understand the structure of word files before you can just go and change something in there (and this is quite ...

16. Nesting stream constructors is not exception safe forums.oracle.com

This problem can be avoided by not nesting the stream constructors and explicitly making a variable for each, but it worries me that such a widely used paradigm is flawed.
