Questions tagged [tostring]

"toString" or "ToString" is a major formatting method or function used in high level programming languages. It converts an Object to its string representation so that it is suitable for display.

toString() is a function which can be overridden.

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. Eclipse, as the best java IDE in the world, should include functionality of automatic toString() method generation to make its users lives even simpler. Implementing it is the aim of this project.

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