Question

You will create a Name class to manage different name
changes of a person.
Variables:
Full Name (e.g. “Hillary Rodham Clinton”)
First Name (e.g. “Hillary”)
Middle Name (e.g. “Diane”)
Last Name (e.g. “Clinton”)
Maiden Name (e.g. “Rodham”)
Number of Names (Hint: static variable)

Constructors:
Name(): Initializes full and first names to “Anonymous” and middle, last
and maiden names to empty string.
Name(String fullName): Initializes full name to fullName and initializes
first, middle and last names appropriately. If only 2 names are in the
fullName, middle name is set to empty string. For all cases, maiden name
is set to empty string.

Method
getFullName(), getFirstName(), getMiddleName(), getLastName(),
getMaidenName(): Return appropriate name. They are all public.
getMiddleInitial(): Returns middle initial.
changeFirstName(String newFirst), changeMiddleName(String
newMiddle): Changes appropriate name and full name. They are all
public.
changeLastName(String newLast): Changes last name. Ask the user if
maiden name should be changed and accept “Yes”, “yes”, “No” and “no”
as answers. If “Yes” or “yes”, then call private changeMaidenName()
method and current last name becomes maiden name and newLast
become new last name.
changeMaidenName(): This method is private. Changes maiden name.
displayNames(): Displays names in the appropriate format.

Explanation / Answer

Dear

// Name.java

public class Name {

    // names
    private String fullName;
    private String firstName;
    private String middleName;
    private String lastName;
    private String maidenName;
    // number of names
    private static int numberOfNames = 0;

    // no argument constructor
    public Name() {
        fullName = firstName = "Anonymous";
        middleName = lastName = maidenName = "";
    }

    // 1-argument constructor
    public Name(String fullName) {

        this.fullName = fullName;
        String[] names = fullName.split(" ");
        if (names.length > 2) {
            firstName = names[0];
            middleName = names[1];
            lastName = names[2];
        } else if (names.length == 2) {
            firstName = names[0];
            middleName = names[1];
        } else if (names.length == 1)
            firstName = names[0];
        maidenName = "";
    }

    // returns full name
    public String getFullName() {
        return fullName;
    }
    // returns first name
    public String getFirstName() {
        return firstName;
    }
    // returns middle name
    public String getMiddleName() {
        return middleName;
    }
    // returns last name
    public String getLastName() {
        return lastName;
    }
    // returns maiden name
    public String getMaidenName() {
        return maidenName;
    }
    // returns initial of middle name
    public char getMiddleInitial() {
        if (middleName != "")
            return Character.toUpperCase(middleName.charAt(0));
        else
            return ' ';
    }

    // changes first name and updates it in full name
    public void changeFirstName(String newFirst) {
        firstName = newFirst;
        fullName = firstName + middleName + maidenName + lastName;
    }

    //changes middle name and updates it in full name
    public void changeMiddleName(String newMiddle) {
        middleName = newMiddle;
        fullName = firstName + middleName + maidenName + lastName;
    }

    //changes last name and updates it in full name
    //asks for user whether the maiden name can modify or not
    public void changeLastName(String newLast) {

        String choise;
        java.util.Scanner input = new java.util.Scanner(System.in);
        System.out.print("Do you want to change the maiden name (yes or no)? ");
        choise = input.nextLine();

        if (choise.equalsIgnoreCase("yes"))
            changeMaidenName(this.lastName);

        this.lastName = newLast;
        fullName = firstName + middleName + maidenName + lastName;
    }

    // private method to change maiden name
    private void changeMaidenName(String newMaiden) {
        maidenName = newMaiden;
    }

    // display the names
    public void displayNames() {
        System.out.println("Full Name: " + fullName);
        System.out.println("First Name: " + firstName);
        System.out.println("Middle Name: " + middleName);
        System.out.println("Last Name: " + lastName);
        System.out.println("Maiden Name: " + maidenName);
        System.out.println("Full Name: " + fullName);
    }
}
