Math 130 Java Programming
Does my code pass the requirements? May I have more explanation? Does my code compile correctly? Is my code readable? Is my code well commented? How may I better organize my code? Are there whitespaces to appropriate help separate distinct parts?
My code:
import java.util.Scanner;
public class TicketSale
{
public static void main(String[] args)
{
Scanner keyboard = new Scanner(System.in);
//Prompt user to input the number of Adult tickets to purchase
System.out.print("Please enter number of adults:"); //Prompt user to input the number of Adult tickets to purchase
int adults = keyboard.nextInt();
//Prompt user to input the number of Children tickets to purchase
System.out.print("Please enter number of children:"); //Prompt user to input the number of Children tickets to purchase
int children = keyboard.nextInt();
//Calculate and display the total cost for adults and children
System.out.print("Your total cost for " + adults + getadulttxt(adults) + " and " + children + getChildtxt(children) + " is: $");
double cost = ticketCost(adults, children); //invoke method
System.out.printf("%.2f", cost);
keyboard.close();
}
//Returns the appropriate text for adult(s) based on the count
public static String getadulttxt(int adults)
{
if(adults > 1)
{
return " adults";
}
else
return " adult";
}
//Returns the appropriate text for child/children based on the count
public static String getChildtxt(int children)
{
if(children > 1)
return " children";
else
return " child";
}
//Calculate the total cost of tickets based on the number of adults and children
public static double ticketCost(int adults, int children)
{
//Calculate ticket prices
double priceperadults = 16.00;
double priceperchild = 8.50;
double pricePeraccompaniedChild = 5.50;
//Calculate the number of accompanied children
int accompaniedChildren = adults * 2;
//Adjust the count of children and accompanied children based on availability
if(children>=accompaniedChildren)
{
children-=accompaniedChildren ;
}
else
{
accompaniedChildren = children;
children = 0;
}
//Calculate the total cost
double total = (priceperchild*children) + (priceperadults *adults) + (pricePeraccompaniedChild * accompaniedChildren);
//Apply discounts based on the number of adults
if(adults >= 20)
{
total *= .90; // Ten percent discount
}
else if(adults>= 10)
{
total*=.94; // Six percent discount
}
return total;
}
}

- Java Assignment: Experiment with naming rules in Java Does the language use static or dynamic scoping? Can scopes nest? Are they open or closed? Does the scope of a name encompass the entire block in which it is declared, or only the portion after the declaration? How does one declare mutually recursive types or subroutines? Can subroutines be passed as parameters, returned from functions, or stored in variables? If so, when are referencing environments bound? Justify your answers with suitable code snippet and its output.arrow_forwardimport java.util.Arrays; import java.util.Random; public class Board { /** * Construct a puzzle board by beginning with a solved board and then * making a number of random moves.
