In Java the Scanner class allows the user to take input from the console. It belongs to the java.util package.It is used to read the input of primitive types like int, double, long, short, float, and byte.

You can use this example below to understand the way the Scanner class helps to take input from the user

import java.util.*;
class UserInputDemo1
{
public static void main(String[] args)
{
Scanner sc= new Scanner(System.in); //System.in is a standard input stream
System.out.print(“Enter your name: “);
String str= sc.nextLine(); //reads string
System.out.print(“Your name is : “+str);
}
}
Output :
Your name is : Sourav //In this case I have taken Input as Sourav so it is printing in the console as Your name is : Sourav
