Explanation / Answer

/**The java program that prompts user to enter
* firstname, lastname, age ,profession ,petname
* and cost of vehicle and creates an paragraphs
* as mentioned in the question and prints the
* paragrapha and number of characters in the
* paragraph.*/
//Paragraph.java
import java.util.Scanner;
public class Paragraph
{
   public static void main(String[] args)
   {      
       //a.Create a Scanner class object
       Scanner scanner=new Scanner(System.in);
      
       //i-v)Declare variables to read input
       //from user
       String firstName;
       String lastName;
       String fullName;
       int age;
       String profession;
       String petname;
       double costOfVehicle;
      
       //sales tax 7.5 %
       final double SALES_TAX=0.075;
      
       //b. Read variables from user
       System.out.println("Enter first name :");
       firstName=scanner.nextLine();
      
       System.out.println("Enter last name :");
       lastName=scanner.nextLine();
      
       System.out.println("Enter age :");
       age=Integer.parseInt(scanner.nextLine());
      
       System.out.println("Enter profession name :");
       profession=scanner.nextLine();
      
       System.out.println("Enter favorite pet name :");
       petname=scanner.nextLine();
      
       System.out.println("Enter cost of first vehicle :");
       costOfVehicle=Double.parseDouble(scanner.nextLine());
      
      
       System.out.println("Paragraph");
      
       //Create the paragraph with required specifications
       String paragraph=firstName+lastName+" founded Sun Microsystems."+
       firstName+" was a child prodigy. The"+ lastName+
       " family is very proud of "+firstName+" and "+" his age is "+age+"."+
       "His profession was "+profession.toUpperCase()+" "+
       " and his favorite pet's name "+petname+"."+
       " The cost of first vehicle was $"+String.format("%.2f", costOfVehicle)+
       " Total cost with sales tax is $"+(costOfVehicle+costOfVehicle*SALES_TAX)+".";
      
       System.out.println(paragraph);
      
       //get the number of characters
       int totalCharacters=paragraph.length();
      
       //print number of characters
       System.out.println("(The above story contained "+totalCharacters+" characters)");
      
      
      
   }
}
