Question

Write a class Name that stores a person’s first, middle, and last names and provides the following methods:

-public Name(String first, String middle, String last)—constructor. The name should be stored in the case given;

don’t convert to all upper or lower case.

-public String getFirst()—returns the first name

-public String getMiddle()—returns the middle name

-public String getLast()—returns the last name

-public String firstMiddleLast()—returns a string containing the person’s full name in order, e.g., “Mary Jane Smith”.

-public String lastFirstMiddle()—returns a string containing the person’s full name with the last name first followed by a comma, e.g., “Smith, Mary Jane”.

-public boolean equals(Name otherName)—returns true if this name is the same as otherName. Comparisons should not be case sensitive. (Hint: There is a String method equalsIgnoreCase that is just like the String method equals except it does not consider case in doing its comparison.)

-public String initials()—returns the person’s initials (a 3-character string). The initials should be all in upper case, regardless of what case the name was entered in. (Hint: Instead of using charAt, use the substring method of String to get a string containing only the first letter—then you can upcase this one-letter string. See Figure 3.1 in the text for a description of the substring method.)

-public int length()—returns the total number of characters in the full name, not including spaces.

2. Now write a program TestNames.java that prompts for and reads in two names from the user (you’ll need first, middle,

and last for each), creates a Name object for each, and uses the methods of the Name class to do the following:

a. For each name, print

-first-middle-last version

-last-first-middle version

-initials

-length

b. Tell whether or not the names are the same.

Explanation / Answer

Here goes the solution for the first problem

Code:

public class Name{
   String firstName;
   String lastName;
   String middleName;
public Name(String first, String middle, String last){
firstName=first;
lastName=last;
middleName=middle;
}
public String getFirst(){
return firstName;
}
public String getMiddle(){
return middleName;
}
public String getLast(){
return lastName;
}
public String firstMiddleLast(){
return firstName+" "+middleName+" "+lastName;
}
public boolean equals(Name otherName){
if(otherName.firstName.equalsIgnoreCase(firstName)&&otherName.middleName.equalsIgnoreCase(middleName)&&otherName.lastName.equalsIgnoreCase(lastName))
       return true;
else
return false;
}
public String initials(){
   return firstName.substring(0,1).toUpperCase()+middleName.substring(0,1).toUpperCase()+lastName.substring(0,1).toUpperCase();
}
public int length(){
    return firstName.length()+lastName.length()+middleName.length();
}
}
