Each of these methods (except nextLine) reads a set of consecutive characters until whitespace (such as a blank or a tab) encountered. The nextShort, nextFloat, and nextLong methods in Scanner work similarly. The various methods of the scanner class are as follows:

Scanner(Readable source): It constructs a new Scanner from a character stream.Scanner(InputStream source, String charsetName): It constructs a new Scanner from a byte input stream using the specified charset.Scanner(InputStream source): It constructs a new Scanner from a byte input stream using the system’s default charset.

Scanner(File source, String charsetName): It constructs a new Scanner that scans the specified file using the specified character set.Scanner(File source): It constructs a new Scanner that scans the specified file using the system’s default charset.A Scanner class to create and obtain input from command window is as follows:

įor example, specifies that Scanner is a class in the package util and util is a package in the package java. Before using a Scanner class, the program must import the package import java.util.* OR. Java Scanner class commonly used to parse a string of text and primitive types using a regular expression. The Java Scanner class that breaks down its input into tokens using any regular expression delimiter that is whitespace by default and it’s useful for parsing files also. Scanner class provides many methods to read and parse various primitive byte, short, int, float, double or even an object of String class. The Java Scanner class extends Object class is present in java.lang package and implements Iterator and Closeable interfaces. It can be used to read a File on the disk. The Scanner class is in java.util package which allows the user to read the data dynamically from the keyboard.
