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; } } Thank you

OOP (Object-Oriented Programming) in Java Applying the composite pattern, you may create a replica of any environment you choose. Any number of media may be used, from photographs to simulators to movies to video games, and so on.

Correct Code for Java: Enter an integer>> 11 Enter another integer>> 23 The sum is 34 The difference is -12 The product is 253 import java.util.Scanner; public class DebugTwo2 { public static void main(String args[]) { int a, b; Scanner input = new Scanner(System.in); System.out.print("Enter an integer>> "); a = nextInt (); System.out.print("Enter b = nextInt (); System.out.println("The System.out.println("The System.out.println("The } } another integer>> "); sum is " + (a + b)); difference is " + (a - b)); product is + (a*b));

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.

import 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. That some of the possible moves * don't actually change what the board looks like. * * @param moves the number of moves to make when generating the board. */ public Board(int moves) { throw new RuntimeException("Not implemented"); } The board is 5 X 5. You can add classes and imports like rand.

Does Java support referential transparency? What about in static contexts like a? What about in object contexts like b? Explain using the following bits of code to explain your answer for each question. a) • static int a,b,c;//declaration • //some stuff happens • result1 = (fun(a) + b) / (fun(a) – c); • temp = fun(a); • result2 = (temp + b) / (temp - c); • /function signature • int static fun(int arg); %3D %3D b) • Employee a = new Employee(); • Employee b = new Employee(); • Employee c= new Employee(); • //some stuff happens • result1 = (a.fun() + b) / (a.fun() – c); • temp = a.fun(); • result2 = (temp + b) / (temp - c); • //function signature inside Employee: • int fun() %3D
