Reading file

[Mariem]

I have files with multiple extensions (docx,txt, html...) which I want to extact their entire content to put it in a jtextarea.
Help me please.

Have you googled this yet? Because how to read a text file is explained very nicely on a lot of sites...
Reading .doc files requires some external library probably, which can be used probably almost the same as the methods you use to read a normal .txt file.

I know how to read .txt files but what I want "what external librarys to use and how if I want to read html or doc file"
