In Java programming, declare a variable that can store three initials

In Java programming, declare a variable that can store three initials (each represented by a single character). Then, display the initials in the format: J.M.F (each initial followed by a period).

J.M.F

T he Correct Answer and Explanation is :

✅ Correct Java Code:

public class Initials {
    public static void main(String[] args) {
        // Declare variables to store three initials
        char firstInitial = 'J';
        char middleInitial = 'M';
        char lastInitial = 'F';

        // Display the initials in the format: J.M.F
        System.out.println(firstInitial + "." + middleInitial + "." + lastInitial);
    }
}

📘 Explanation:

In Java, characters are represented using the char data type, which stores a single 16-bit Unicode character. Each char value must be enclosed in single quotes (e.g., 'A', 'z', '3'). In this program, we want to store three initials—each being a single character—so we declare three char variables: firstInitial, middleInitial, and lastInitial.

char firstInitial = 'J';
char middleInitial = 'M';
char lastInitial = 'F';

These variables store the initials “J”, “M”, and “F” respectively.

To display the initials in the desired format (J.M.F), we use System.out.println() to print the characters along with periods . as separators.

System.out.println(firstInitial + "." + middleInitial + "." + lastInitial);

In Java, the + operator can be used for string concatenation when one or more operands are strings. Even though char is not a string type, when used in a + operation with a string (like "."), the characters are automatically converted into strings and concatenated.

So, firstInitial + "." becomes "J.", then "J." + "M" becomes "J.M", and so on. The final result printed is J.M.F.

This is a common approach in Java for formatting output involving characters and strings. It demonstrates basic principles of variable declaration, data types, and output formatting, which are essential for beginner-level programming in Java.
