The reset() method in Java’s Scanner class is used to reset the scanner’s state to its default. This includes clearing any custom delimiter or locale settings that might have been applied to the scanner. After calling this method, the scanner behaves as if it was newly created.
Key Points:
The method does not rewind the input stream or change its position.
It simply resets the scanner’s configuration, such as delimiters and locales.
Common Use Case:
The reset() method is useful when you need to reuse the same scanner instance with default settings after modifying its behavior.
For example:
If you changed the delimiter to a custom pattern, you can reset the scanner to use the default delimiter (whitespace).
If you set a specific locale, resetting will revert it to the default locale.
