# --> Java User Input (Scanner)

### Java User Input

The `Scanner` class is used to get user input, and it is found in the `java.util` package.

To use the `Scanner` class, create an object of the class and use any of the available methods found in the `Scanner` class documentation. In our example, we will use the `nextLine()` method, which is used to read Strings:

#### Example

```java
import java.util.Scanner;  // Import the Scanner class

class MyClass {
  public static void main(String[] args) {
    Scanner myObj = new Scanner(System.in);  // Create a Scanner object
    System.out.println("Enter username");

    String userName = myObj.nextLine();  // Read user input
    System.out.println("Username is: " + userName);  // Output user input 
  }
}
```

### Input Types

In the example above, we used the `nextLine()` method, which is used to read Strings. To read other types, look at the table below:

| Method          | Description                           |
| --------------- | ------------------------------------- |
| `nextBoolean()` | Reads a `boolean` value from the user |
| `nextByte()`    | Reads a `byte` value from the user    |
| `nextDouble()`  | Reads a `double` value from the user  |
| `nextFloat()`   | Reads a `float` value from the user   |
| `nextInt()`     | Reads a `int` value from the user     |
| `nextLine()`    | Reads a `String` value from the user  |
| `nextLong()`    | Reads a `long` value from the user    |
| `nextShort()`   | Reads a `short` value from the user   |

In the example below, we use different methods to read data of various types:

#### Example

```java
import java.util.Scanner;

class MyClass {
  public static void main(String[] args) {
    Scanner myObj = new Scanner(System.in);

    System.out.println("Enter name, age and salary");

    // String input
    String name = myObj.nextLine();

    // Numerical input
    int age = myObj.nextInt();
    double salary = myObj.nextDouble();

    // Output input by user
    System.out.println("Name: " + name); 
    System.out.println("Age: " + age); 
    System.out.println("Salary: " + salary); 
  }
}
```
