As we can see from the above example, we need to import the java.util.Scanner package before we Create a Scanner Object in Java. Once we import java.util.Scanner; class Main { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Product name: "); String product_name = input.next(); System.out.print("Value entered: " + product_name); System.out.print("Quantity: "); int quantity = input.nextInt(); System.out.print("Value entered: " + quantity); System.out.print("On display: "); boolean on_display = input.nextBoolean(); System.out.print("Value entered: " + on_display); } } The Scanner class provides a versatile way of reading data of various types including Files, The input data must be delimited by some character. By default the delimiters are white space (space, tabs, and new lines).
With so many decision points--sensor technology, resolution, bit depth, speed, hardware interface, software--picking the right scanner can be a challenge. Sometimes I think the history of computer technology is the history of listening
Java Scanner Class Java Scanner class breaks the input into tokens using a delimiter which is whitespace by default. It is the easiest way to read input in Java program, With the help of Scanner in Java, we can get input from the user in primitive types such as int, long, double, byte, float, short, etc. Scanner sc = new Scanner(System.in); and in the past, Eclipse would add the import java.util.Scanner or import java.util.* line above my class.
