Defining the inputStream object

Question regarding extend issue

What is the reason behind defining the inputStream object in this way...

Code:
InputStream inputStream = new FileInputStream("c:\\input.txt");

I know that FileInputStream extends InputStream, is there anything else ?

I mean we could have define it like
Code:
FileInputStream inputStream = new FileInputStream("c:\\input.txt");


Thank you

Net::DNS::Question(3)					User Contributed Perl Documentation				     Net::DNS::Question(3)

NAME
Net::DNS::Question - DNS question class SYNOPSIS
"use Net::DNS::Question" DESCRIPTION
A "Net::DNS::Question" object represents a record in the question section of a DNS packet. METHODS
new $question = Net::DNS::Question->new("example.com", "MX", "IN"); Creates a question object from the domain, type, and class passed as arguments. RFC4291 and RFC4632 IP address/prefix notation is supported for queries in in-addr.arpa and ip6.arpa subdomains. parse ($question, $offset) = Net::DNS::Question->parse($data, $offset); Parses a question section record at the specified location within a DNS packet. The first argument is a reference to the packet data. The second argument is the offset within the packet where the question record begins. Returns a Net::DNS::Question object and the offset of the next location in the packet. Parsing is aborted if the question object cannot be created (e.g., corrupt or insufficient data). qname, zname print "qname = ", $question->qname, " "; print "zname = ", $question->zname, " "; Returns the domain name. In dynamic update packets, this field is known as "zname" and refers to the zone name. qtype, ztype print "qtype = ", $question->qtype, " "; print "ztype = ", $question->ztype, " "; Returns the record type. In dymamic update packets, this field is known as "ztype" and refers to the zone type (must be SOA). qclass, zclass print "qclass = ", $question->qclass, " "; print "zclass = ", $question->zclass, " "; Returns the record class. In dynamic update packets, this field is known as "zclass" and refers to the zone's class. print $question->print; Prints the question record on the standard output. string print $qr->string, " "; Returns a string representation of the question record. data $qdata = $question->data($packet, $offset); Returns the question record in binary format suitable for inclusion in a DNS packet. Arguments are a "Net::DNS::Packet" object and the offset within that packet's data where the "Net::DNS::Question" record is to be stored. This information is necessary for using compressed domain names. COPYRIGHT
