Question

Create a class named Module2. You should submit your source code file (Module2.java). The Module2 class should contain the following data fields and methods (note that all data and methods are for objects unless specified as being for the entire class)

1. Data fields:
   1. A String object named firstName
   2. A String object named middleName
   3. A String object name lastName
2. Methods:
   1. A Module2 constructor method that accepts no parameters and initializes the data fields from 1) to empty Strings (e.g., firstName = "";)
   2. A method named monogram that accepts two parameter Strings s and t and returns, as a String, the first character from s followed by the first character from t
   3. A method named monogram that accepts three parameter Strings s, t, u and returns, as a String, the first character from s followed by the first character from t followed by the first character from u
   4. A method named completeName that accepts two parameter Strings s and t and returns, as a String, s followed by a space, followed by t
   5. A method named completeName that accepts three parameter Strings s, t, u and returns, as a String, s followed by a space, followed by t, followed by a space, followed by u
   6. A method named getName that accepts a parameter String prompt and does the following: creates a Scanner object, prints prompt to the console, uses Scanner's nextLine method to read the user input, and returns the String obtained from Scanner's nextLine method
   7. A main method that, in order:
      • Creates a new Module2 object using the constructor from a)
      • Prints the text “starting application” to the console
      • Calls method f) three times with arguments "Please enter your first name", "Please enter your middle name", and "Please enter your last name", storing the results in the three String fields firstName, middleName, and lastName
      • Creates a Scanner object, prompts the user to generate monograms and complete name using either first & last or first & middle & last names, with Scanner's nextInt method
        1. If the user entered 2, calls methods b) and d) with arguments (firstName, lastName) and prints the returned Strings to the console with appropriate labels (e.g., "two name monogram" for b)
        2. If the user entered 3, calls methods c) and e) with arguments (firstName, middleName lastName) and prints the returned Strings to the console with appropriate labels (e.g., "three name monogram" for c)
      • Prints the text “ending application” to the console

The program should be implemented as a single file holding the public class Module2.

Answer 1

code

import java.util.Scanner;

public class Module2 {

String firstName,lastName,middleName;

public Module2()
{
firstName="";
lastName="";
middleName="";
}
public String monogram (String s,String t)
{
return s.charAt(0)+""+t.charAt(0);
}
public String monogram (String s,String t,String u)
{
return s.charAt(0)+""+t.charAt(0)+u.charAt(0);
}
public String completeName (String s,String t)
{
return s+" "+t;
}
public String completeName (String s,String t,String u)
{
return s+" "+t+" "+u;
}
public String getName(String prompt)
{
Scanner input=new Scanner(System.in);
System.out.print(prompt);
return input.nextLine();
}
public static void main(String[] args)
{
Module2 obj=new Module2();
obj.firstName=obj.getName("Please enter your first name: ");
obj.middleName=obj.getName("Please enter your middle name: ");
obj.lastName=obj.getName("Please enter your last name: ");
Scanner sc=new Scanner(System.in);
  
System.out.println("\nEnter 2. for generate monograms and complete name using either first & last");
System.out.println("Enter 3. for generate monograms and complete name using either first & last & middle names");
System.out.print("Your Choice: ");
int userChoice=sc.nextInt();

if(userChoice==2)
{
System.out.println("\nTwo name monogram: "+obj.monogram(obj.firstName, obj.lastName));
System.out.println("Compelete name is: "+obj.completeName(obj.firstName, obj.lastName));
}
if(userChoice==3)
{
System.out.println("\nThree name monogram: "+obj.monogram(obj.firstName, obj.lastName,obj.middleName));
System.out.println("Compelete name is: "+obj.completeName(obj.firstName, obj.lastName,obj.middleName));
}
}
  
}

output
