what is scanner in java

The Scanner class in Java is a part of the java.util package and is used for obtaining user input and parsing it into primitive data types such as int, double, etc., and strings. It creates a bi-directional communication between the software and its user, allowing the user to enter information that the software can use to inform its behavior. This is essential for software that requires user interaction, such as games or applications that require user input. The Scanner class provides various methods for reading different types of input, such as nextLine() for reading strings, nextInt() for reading integers, and so on
