📝 Java Program to Take Character Input from the User

💡 Introduction:

In Java, taking input from the user is commonly done using the Scanner class from the java.util package. However, since Java doesn’t have a direct method to read a single character, we usually take a string input and extract its first character.

This program demonstrates how to take a character input from the user in Java.

💻 Java Program:

// Java program to take character input from the user
import java.util.Scanner;

public class CharacterInputExample {
    public static void main(String[] args) {
        // Create Scanner object for taking input
        Scanner sc = new Scanner(System.in);

        // Ask the user to enter a character
        System.out.print("Enter a character: ");

        // Take input as a string and extract first character
        char ch = sc.next().charAt(0);

        // Display the entered character
        System.out.println("You entered: " + ch);

        // Close the scanner
        sc.close();
    }
}

⚙️ Explanation:

1. Scanner sc = new Scanner(System.in);
   → Creates a Scanner object to take input from the user.

2. sc.next()
   → Reads the next token (word or letter) entered by the user.

3. charAt(0)
   → Extracts the first character of the entered string.

4. System.out.println()
   → Displays the character entered by the user.

🧠 Example Output:

Enter a character: A
You entered: A

🪄 Tip:

If you want to handle multiple characters or strings, you can directly use sc.nextLine() to read the entire line.
