15.8 The Object Methods

The URLConnection
class overrides only one method from
java.lang.Object, toString( ):

public String toString( )

Even so, there is little reason to print a
URLConnection object or to convert one to a
String, except perhaps if you are debugging.
toString( ) is called the same way as every other
toString( ) method.
