Question

I Need Help with this using Java Programming :

Class name fname Iname Class variable total Number Constructor (no arguments) Constructor (takes two arguments, fname and Iname) One getter method to return the fname and Iname One setter method for fname and Iname Inside Main: Create three obj namesS Jill Doe John James Jack Smith When creating the first object (Should not be an anonymous object) Then use the setter method to assign the fname and Iname Then use the getter method to display the information for the first object When creating the second object (Should not be an anonymous object) to set the fname and Iname use the two arg then use the getter method to display the information for the second object When dealing with he third object (All of this should happen using one single statement) string and then display the string. Remember that all of this code should be in a single statement Every time you add an abject increment total number by 1. This increment should only happen in the argument-less constructor's tour Create an anonymous, third object using the two argument constructor. Use the getter method to retrieve fname and Iname as a single This means that if you call the two argument constructor, you have to revere to the argument-less constructor as well Before the end of the program, display the number of objects that were created by displaying the contents of totalNumber

Class name

fname

lname

Class variable

total Number

Constructor (no arguments)

Constructor (takes two arguments, fname and lname)

One getter method to return the fname and lname

One setter method for fname and lname

Inside Main:

Create three objects with the following names

Jill Doe

John James

Jack Smith

When creating the first object (Should not be an anonymous object)

use the argument-less constructor

Then use the setter method to assign the fname and lname

Then use the getter method to display the information for the first object

When creating the second object (Should not be an anonymous object)

use the two argument constructor to set the fname and lname

then use the getter method to display the information for the second object

When dealing with he third object (All of this should happen using one single statement)

Create an anonymous, third object using the two argument constructor. Use the getter method to retrieve fname and lname as a single string and then display the string. Remember that all of this code should be in a single statement.

Every time you add an abject increment total number by 1. This increment should only happen in the argument-less constructor’s tour. This means that if you call the two argument constructor, you have to revere to the argument-less constructor as well.

Before the end of the program, display the number of objects that were created by displaying the contents of totalNumber

Thank You :)

Answer 1

class Name {
        private String fname, lname;
        public static int totalNumber = 0;

        public Name() {
                fname = "DEFAULT";
                lname = "DEFAULT";
                totalNumber++;
        }

        public Name(String fname, String lname) {
                this();
                this.fname = fname;
                this.lname = lname;
        }

        public void setName(String fname, String lname) {
                this.fname = fname;
                this.lname = lname;
        }

        public String getName() {
                return this.fname + " " + this.lname;
        }
}

public class NameDemo {

        public static void main(String[] args) {
                Name n1 = new Name();
                n1.setName("Jill", "Doe");
                System.out.println(n1.getName());
                
                Name n2 = new Name("John", "James");
                System.out.println(n2.getName());
                
                System.out.println(new Name("Jack", "Smith").getName());
                
                System.out.println("total objects created: " + Name.totalNumber);
        }

}

Please upvote, as i have given the exact answer as asked in question. Still in case of any concerns in code, let me know in comments. Thanks!
