The toString method is a fundamental concept in object-oriented programming, particularly prevalent in languages like Java and C#. It refers to a special method that is automatically invoked when an object needs to be represented as a string. The primary purpose of the toString method is to provide a human-readable and informative string representation of an object's state.

When you attempt to print an object directly to the console or convert it to a string using built-in functions, the system often calls the object's toString method behind the scenes. By default, most programming languages provide a generic implementation of toString that might simply return the object's class name followed by its memory address. This default representation is often not very useful for debugging or displaying meaningful information.

Therefore, it is common practice for developers to override the default toString method in their custom classes. By overriding it, they can define what information should be included in the string representation. This typically involves concatenating the values of the object's important fields or properties into a coherent string. For instance, a `Person` object might override toString to return a string like "Person{name='John Doe', age=30}". This makes it much easier to inspect the object's data.

The toString method is not just for debugging; it can also be used in various other contexts, such as logging, displaying data in user interfaces, or when objects are used in data structures that require string keys. Effectively implementing a useful toString method can significantly improve the developer experience and the overall understandability of code.
