In Java, you can take character input from the user using various methods, but one common approach is to read character input from the console using classes from the `java.io` package. Here's an example of how to do it using the `Scanner` class:

1. Import the necessary classes:

```java
import java.util.Scanner;
```

2. Create a `Scanner` object to read from the console:

```java
Scanner scanner = new Scanner(System.in);
```

3. To read a single character from the user, you can use the `next` method of the `Scanner` class and then convert it to a character:

```java
System.out.print("Enter a character: ");
String input = scanner.next();
char character = input.charAt(0);
```

Here's a complete example:

```java
import java.util.Scanner;

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

        System.out.print("Enter a character: ");
        String input = scanner.next();

        if (input.length() == 1) {
            char character = input.charAt(0);
            System.out.println("You entered: " + character);
        } else {
            System.out.println("Please enter only one character.");
        }

        scanner.close(); // Don't forget to close the Scanner when done.
    }
}
```

In this example, the program prompts the user to enter a character, reads the input as a string, and then extracts the first character from the string to obtain the character input. It also includes a check to ensure that only one character is entered.

Remember to close the `Scanner` object using `scanner.close()` when you are done to release system resources associated with it.
