\u2705 Correct Java Code:<\/h3>\n\n\n\n
public class Initials {\n    public static void main(String[] args) {\n        \/\/ Declare variables to store three initials\n        char firstInitial = 'J';\n        char middleInitial = 'M';\n        char lastInitial = 'F';\n\n        \/\/ Display the initials in the format: J.M.F\n        System.out.println(firstInitial + \".\" + middleInitial + \".\" + lastInitial);\n    }\n}\n<\/code><\/pre>\n\n\n\n

\ud83d\udcd8 Explanation:<\/h3>\n\n\n\n
In Java, characters are represented using the char<\/code> data type, which stores a single 16-bit Unicode character. Each char<\/code> value must be enclosed in single quotes (e.g., 'A'<\/code>, 'z'<\/code>, '3'<\/code>). In this program, we want to store three initials\u2014each being a single character\u2014so we declare three char<\/code> variables: firstInitial<\/code>, middleInitial<\/code>, and lastInitial<\/code>.<\/p>\n\n\n\n
char firstInitial = 'J';\nchar middleInitial = 'M';\nchar lastInitial = 'F';\n<\/code><\/pre>\n\n\n\n
These variables store the initials “J”, “M”, and “F” respectively.<\/p>\n\n\n\n
To display the initials in the desired format (J.M.F<\/code>), we use System.out.println()<\/code> to print the characters along with periods .<\/code> as separators.<\/p>\n\n\n\n
System.out.println(firstInitial + \".\" + middleInitial + \".\" + lastInitial);\n<\/code><\/pre>\n\n\n\n
In Java, the +<\/code> operator can be used for string concatenation<\/strong> when one or more operands are strings. Even though char<\/code> is not a string type, when used in a +<\/code> operation with a string (like \".\"<\/code>), the characters are automatically converted into strings and concatenated.<\/p>\n\n\n\n
So, firstInitial + \".\"<\/code> becomes \"J.\"<\/code>, then \"J.\" + \"M\"<\/code> becomes \"J.M\"<\/code>, and so on. The final result printed is J.M.F<\/code>.<\/p>\n\n\n\n
This is a common approach in Java for formatting output involving characters and strings. It demonstrates basic principles of variable declaration<\/strong>, data types<\/strong>, and output formatting<\/strong>, which are essential for beginner-level programming in Java.<\/p>\n\n\n\n
