Examples of java.net.URL.openStream()

java.net.URL.openStream()
Opens a connection to this URL and returns an InputStream for reading from that connection. This method is a shorthand for:
```
 openConnection().getInputStream() 
```
@return an input stream for reading from the URL connection. @exception IOException if an I/O exception occurs. @see java.net.URL#openConnection() @see java.net.URLConnection#getInputStream()
