![]() Scanner(File source): constructs a Scanner to scan the specified file using the system’s default charset.* How to construct a Scanner?We can create an instance of the Scanner class to parse a byte input stream, a character input stream or a String, using one of the following constructors (to name a few): ![]() Int number = scanner.nextInt() Let’s understand how to create an instance of a Scanner and its primary methods. Here’s the simplest example of using a Scanner to read an integer number from the user: Scanner scanner = new Scanner(System.in) ![]() The parsed tokens can be converted into primitive types and Strings using various next methods. * How does a Scanner work?Basically, a Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace (blanks, tabs, and line terminators). In this Java File IO tutorial, you will understand how the Scanner class works with various examples which you can use for your daily Java coding.
