Define what you mean by "start doing comparison."

File f2 = new File("file.doc");

File f1 = new File("file.txt");

f1.createNewFile();

f2.createNewFile);

There, I've created a file with a .doc extension and one with a .txt extension.

Note that the notion of file "type" being related to the filename extension is simply a matter of convention--the various apps that open files assume that if a file has a .doc extension then it's a Word doc, but there's no magic in the file system to make that happen. I can write plain text out to a .doc file, write Word format out to a .txt file, and write a Java class file out to a .html fle.

If you want to create a Word document--that is a file whose contents are in Word format--the extension has nothing to do with that. You'll need to google for a library that will do that for you. However, since you asked this question in the first place, I suspect using such a library might be beyond you current skill level.

I really don't understand these requirements. Making sure that you do and getting them spelled out clearly and precisely is the first step.
