## Overview
There are different default packages available in Java to facilitate the programmer. The **`java.util`** is one such package that contains a collection of different classes and frameworks.


**`Scanner`** is a class available in the `java.util` package. It is used to take input from a user for any primitive datatype (int, float, string, and so on).

## Syntax
Before using the `Scanner` class, we need to import it.
```java
import java.util.Scanner;
```
We can then create an object of the `Scanner` class by using the following syntax:
```java
Scanner sc= new Scanner(System.in);
```
We are using `sc` as an example here, but we can also use any other variable name instead.

## Parameters
-  **`System.in`**: This represents the object of the input stream. If we want to read the input from a file, then `System.in` is replaced by an object of the `file` class.

## Example code
The example below shows how we can take input from a user using the `Scanner` class object. 

import java.util.Scanner;
class ScannerExample {
    public static void main(String args[]){
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter your Roll number");
        int id = sc.nextInt();
        System.out.println("Enter your grade");
        char grade = sc.next().charAt(0);
        System.out.println("Roll Number :" + id);
        System.out.println("Grade :" + grade);
    }
}

## Code explanation
- Line 1: We import the `Scanner` class.
- Line 4: We create the object `sc` of the `Scanner` class.
- Lines 5–6: We take an integer input from the user.
- Lines 7–8: We take a character input from the user.
- Lines 9–10: We display the inputs entered by the user.  

What is java.util.Scanner in Java?

The java.util.Scanner class facilitates user input for various datatypes in Java after being imported and instantiated.
