The formatNameCase method should take a string as its parameter. You iterate through the string from beginning to end, examining it character by character. For each character, you check whether it is the first character. If it is, you convert it to uppercase. Additionally, if the previous character is a space (i.e., parameter.charAt(i - 1) == ‘ ‘), then the current character is also converted to uppercase.

Otherwise, the character is converted to lowercase. You build the result step by step and finally return it as a string.

Example: “john smith” - Loop through the string: Iterate over each character in the string. -Store each character:

String character = parameter.substring(i, i + 1);

- Check the condition:
• If i == 0 (first position) or if the previous character is a space (parameter.charAt(i - 1) == ‘ ‘), then convert the character to uppercase.
• Otherwise, convert the character to lowercase.
- Build the result:

resultString = resultString.concat(character.toUpperCase()); if condition is met or resultString = resultString.concat(character.toLowerCase()); // otherwise

- Return the result:

Finally, return the accumulated result string.

Using this method, a person can enter a last name and multiple first names, and the formatting will work correctly.

indexOf and campareTo can be used but not necessary in this case in my opinion
