toString

The toString() method is widely used to represent objects as human-readable text and practically every class should implement it. Usually it is very simple: generated string contains the object type and lists values of the most important fields. That's why process of writing such methods can easilly be automated.

Java represents this as the toString() method where C# represents it as ToString().
