This program, URLdemo, opens a connection to a web site specified by a URL (Uniform Resource Locator), for the purpose of reading text from a file at that site. It constructs an object of the Java API class, java.net.URL, which enables convenient handling of URLs. Then, it calls a method on the URL object, to open a connection.
To read and display the lines of text at the site, URLdemo uses classes from the Java I/O package java.io. It creates an InputStreamReader object, and then uses that object to construct a BufferedReader object. Finally, it calls a method on the BufferedReader object to read the specified number of lines from the site.
