J.M.F<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

\u2705 Correct Java Code:<\/h3>\n\n\n\n
public class InitialsDisplay {\n    public static void main(String[] args) {\n        \/\/ Declare variables to store initials\n        char firstInitial = 'J';\n        char middleInitial = 'M';\n        char lastInitial = 'F';\n\n        \/\/ Display initials in the format: J.M.F\n        System.out.println(firstInitial + \".\" + middleInitial + \".\" + lastInitial);\n    }\n}<\/code><\/pre>\n\n\n\n
\n\n\n\n
\ud83e\udde0 Explanation (300+ words):<\/h3>\n\n\n\n
In Java, when we want to store individual characters, we use the char<\/code><\/strong> data type. The char<\/code> data type in Java is used to store a single 16-bit Unicode character. Each character must be enclosed in single quotes, like 'A'<\/code>, 'M'<\/code>, or 'F'<\/code>.<\/p>\n\n\n\n
In the code above, we declare three char<\/code> variables:<\/p>\n\n\n\n
char firstInitial = 'J';\nchar middleInitial = 'M';\nchar lastInitial = 'F';<\/code><\/pre>\n\n\n\n
Each of these stores one initial. Then, we use System.out.println()<\/code> to display them in the specified format.<\/p>\n\n\n\n
To format the initials like J.M.F<\/strong>, we concatenate the characters and string literals (the periods) using the +<\/code> operator. In Java, the +<\/code> operator is used both for numeric addition and for string concatenation. When used with strings or characters, it joins them together into one string.<\/p>\n\n\n\n
System.out.println(firstInitial + \".\" + middleInitial + \".\" + lastInitial);<\/code><\/pre>\n\n\n\n
Let\u2019s break this line down:<\/p>\n\n\n\n
    \n
  1. firstInitial + \".\"<\/code> results in something like 'J' + \".\"<\/code>, which becomes \"J.\"<\/code><\/li>\n\n\n\n
  2. Then, \"J.\" + middleInitial<\/code> becomes \"J.M\"<\/code><\/li>\n\n\n\n
  3. Next, \"J.M\" + \".\"<\/code> becomes \"J.M.\"<\/code><\/li>\n\n\n\n
  4. Finally, \"J.M.\" + lastInitial<\/code> becomes \"J.M.F\"<\/code><\/li>\n<\/ol>\n\n\n\n
    The System.out.println()<\/code> method then prints this final string to the console.<\/p>\n\n\n\n
    This program is simple but demonstrates key Java principles:<\/p>\n\n\n\n
      \n
    • Variable declaration<\/li>\n\n\n\n
    • Use of the char<\/code> data type<\/li>\n\n\n\n
    • String concatenation<\/li>\n\n\n\n
    • Output with System.out.println()<\/code><\/li>\n<\/ul>\n\n\n\n
      This is a common beginner-level exercise to reinforce character handling and string manipulation in Java, especially useful in learning how to structure formatted outputs.<\/p>\n","protected":false},"excerpt":{"rendered":"
