Question

This question concerns writing a Student class to model a student's name, composed
of a first name, middle name and last name. The Student class should meet the
following specification:

Class Student A Student object represents a student. A student has a first name, middle name and last name. Methods public void setNames(String first, String middle, String last) // Set the first, middle and last names of this Student object. public String getFullName() // Obtain the full name of this Student with the middle name converted to an initial only.

Thinking of the problem in terms of testing, there are three requirements that must be
met:
1. The setNames() method sets the names stored in the object i.e. the values of
firstName, middleName, lastName.
2. The getFullName() method obtains the name of the student with the middle name
converted to an initial only.
3. The getFullName() method does not change anything – i.e. it does not modify the
values of firstName, middleName, lastName
HINT: To start your Student class, we suggest using the following instance variables:
Instance variables
private String firstName;
private String middleName;
private String lastName;
In order to test the requirement above create a java class called StudentTest that allows
the user to enter the first name, middle name and last name. These values must be set
using the created set meothod and afterwards displays the information back to the
console, however the Middle name is an initial ONLY

Answer 1

// The code for the above problem is given below with the screenshots for indentation

// and output and if you feel any problem then feel free to ask

// importing Scanner for taking the input from the user

import java.util.Scanner;

// defining the class Student according to the requirements

class Student

{

// declaring the private data members for first, middle and last names

private String firstName;

private String middleName;

private String lastName;

// Default constructor to initialize all the data members with empty strings

public Student()

{

firstName = "";

middleName = "";

lastName = "";

}

// setNames function to set the value of data members according to the entered data

public void setNames(String first, String middle, String last)

{

firstName = first;

middleName = middle;

lastName = last;

}

// getFullName function to return the full name of the student with middle converted to initial only

// without changing any of the value of actual data members

public String getFullName()

{

String fullName;

fullName = firstName +" "+Character.toUpperCase(middleName.charAt(0))+". "+lastName;

return fullName;

}

}

// Defining a class StudentTest to test the working of Student class

class StudentTest

{

public static void main(String[] args)

{

// creating an object of Scanner for input from the user

Scanner Sc = new Scanner(System.in);

// creating an object of Student for entering its details

Student S1 = new Student();

// declaring strings to be entered by the user

String firstName,middleName,lastName;

// taking input for the first, middle and last name from the user

System.out.print("Enter the first name: ");

firstName = Sc.nextLine();

System.out.print("Enter the middle name: ");

middleName = Sc.nextLine();

System.out.print("Enter the last name: ");

lastName = Sc.nextLine();

// calling the setNames function to set the name for object S1

S1.setNames(firstName, middleName, lastName);

// Printing the full name of Object S1 with middle name converted to initial only

System.out.println("The full name of the student with middle converted to initial only: "+S1.getFullName());

// closing the object of scanner to prevent memory leaks

Sc.close();

}

}
