Since the Scanner class implements the AutoCloseable interface, we can use it with the try-with-resources structure to let the compiler adds the code to close it implicitly.Next, we show you various examples using the Scanner class. * Closing the Scanner:We should close the Scanner after use by invoking its close()method. This can be useful in as we don’t want to parse a certain input. It’s also possible to use a regular expression as a delimiter for more advanced parsing.The useLocale(Locale) method specifies a locale which is different than the system’s default locale.The skip(String pattern) method skips an input that matches the pattern. These methods throw InputMismatchException if the next token cannot be converted to the specified type throw NoSuchElementException if the input is exhausted and throw IllegalStateException if the scanner is closed.The useDelimiter(String pattern)method specifies a delimiter different than the default whitespace. These methods throw IllegalStateException if the scanner is closed.The next()method returns the next token as a String.The nextXXX()method return the next token as a value of the specified type. the hasNextInt()method returns true if the next token can be converted to an integer number. The hasNext() method returns true if the scanner has another token in its input.The hasNextXXX() method returns true if the next token can be converted to the specified type, e.g. We can also use different delimiter and locale. * Scanner’s Primary Methods:The Scanner class provides various methods for reading tokens from an input source. Note that these constructors throw FileNotFoundException if the specified file does not exist, or IllegalArgumentException if the specified charset is not found. Scanner(String source): constructs a Scanner from a String.Scanner(Readable source): constructs a Scanner from a character stream.Scanner(InputStream source, String charsetName): constructs a Scanner from a byte input stream using the specified charset.Scanner(InputStream source): constructs a Scanner from a byte input stream using the system’s default charset.Scanner(File source, String charsetName): constructs a Scanner to scan the specified file using the specified character set.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).
