Question

BufferedReader buf2=new BufferedReader(
    new InputStreamReader(new FileInputStream("D:/info.txt")));

Out of these two methods for reading the contents of a file which method is better and why?

BufferedReader buf=new BufferedReader(new FileReader("D:/info.txt"));

Answer 1

Both lines are equivalent; in both cases you’ll get a BufferedReader which will allow you to read text from the file.

A possible advantage of the first approach is that you can change it slightly to specify the character encoding that you want to use for reading the file, for example:

BufferedReader buf2 = new BufferedReader(new InputStreamReader(
    new FileInputStream("D:/info.txt"), "UTF-8"));

FileReader does not allow you to specify the character encoding and will always use the default character encoding of your platform, which is not always what you want.
