I get an error in my code, here is the prompt and code along with the error.

Write a spell checking program (java) which uses a dictionary of words (input by the user as a string) to find misspelled words in a second string, the test string. Your program should prompt the user for the input string and the dictionary string. A valid dictionary string contains an alphabetized list of words.

Functional requirements:

1. For each word in the input string, your program should search the dictionary string for the given word. If the word is not in the dictionary, you program should print the message "Unknown word found" to standard output.
2. After traversing the entire input string, your program should print a message describing the total number of misspelled words in the string.
3. A dictionary string may contain words in uppercase, lowercase, or a mixture of both. The test string may also combine upper and lower case letters. You program should recognize words regardless of case. So if "dog" is in the dictionary string, the word "dOG" should be recognized as a valid word. Similarly, if "CaT" is in the dictionary string, the word "cat" she be recognized as a valid word.
4. Within a string, a word is a white-space delimited string of characters. So the last word in "Hello world!" is "world!".

CODE:

dictionary.java

import java.io.*;
import java.util.*;

public class dictionary
{
public static void main(String args[]) throws Exception
{
     
  
   String dString;
   String uString;

   System.out.println("Enter distionary string :");
  
   dString = input.nextLine();
  
   System.out.println("Enter input string :");
  
   uString = input.nextLine();
  
   String[] dict = dString.split(" ");//split dictionay string and save to array fo string
  
   boolean found = false;
  
   //ieterate over dictionary string array
   for (String a : dict)
   {
       //compare and print message accordingly       
       if((uString.toLowerCase().compareTo(a.toLowerCase())) == 0)
       {
   System.out.println("word found!");
           found = true;
           break;
       }
   }
  
   if(found == false)
   {
       System.out.println("Unknown word found!");
   }

Swathmore Clothing Corporation grants its customers 30 days’ credit. The company uses the allowance method for its uncollectible accounts receivable. During the year, a monthly bad debt accrual is made by multiplying 2% times the amount of credit sales for the month. At the fiscal year-end of December 31, an aging of accounts receivable schedule is prepared and the allowance for uncollectible accounts is adjusted accordingly. At the end of 2017, accounts receivable were $584,000 and the allowance account had a credit balance of $48,000. Accounts receivable activity for 2018 was as follows: Beginning balance $ 584,000 Credit sales 2,670,000 Collections (2,533,000 ) Write-offs (44,000 ) Ending balance $ 677,000 The company’s controller prepared the following aging summary of year-end accounts receivable: Summary Age Group Amount Percent Uncollectible 0–60 days $ 395,000 5 % 61–90 days 94,000 14 91–120 days 54,000 24 Over 120 days 134,000 35 Total $ 677,000 Required: 1. Prepare a summary journal entry to record the monthly bad debt accrual and the write-offs during the year. 2. Prepare the necessary year-end adjusting entry for bad debt expense. 3-a.

Using only <iostream>, implement a dynamic array. You are to build a class called MyDynamicArray. Your dynamic array class should manage the storage of an array that can grow and shrink. The public methods of your class should be the following:

MyDynamicArray(); Default Constructor. The array should be of size 2.

MyDynamicArray(int s); For this constructor the array should be of size s.

~MyDynamicArray();Destructor for the class.

int& operator[](int i); Traditional [] operator. Should print a message if i is out of bounds and return a reference to a zero value.

void add(int v); increases the size of the array by 1 and stores v there.

void del(); reduces the size of the array by 1.

int length(); returns the length of the array.

int clear(); Frees any space currently used and starts over with an array of size 2.

Here is a sample main.cpp file:
#include <iostream>
using namespace std;
#include "MyDynamicArray.cpp"
int main() {
MyDynamicArray x;
for (int i=0; i<100; i++){
x.add(i);
}
int sum = 0;
for (int i=0; i<x.length(); i++){
sum+=x[i];
}
cout << "The sum is : " << sum << endl;
for (int i=0; i<95; i++)
x.del();
x[60] = 27;

MyDynamicArray y(10);
for (int i=0; i<y.length(); i++) y[i] = i*i;
for (int i=0; i<200; i++){
y.add(i);
}
sum = 0;
for (int i=0; i<y.length(); i++){
sum+=y[i];
}
cout << "The sum is : " << sum << endl;
for (int i=0; i<195; i++)
y.del();
y[60] = 27;
for (int i=0; i<200; i++){
y.add(i);
}
sum = 0;
for (int i=0; i<y.length(); i++){
sum+=y[i];
}
cout << "The sum is : " << sum << endl;

}

Using Appendix 4 for ∆Hf ° and ΔS˚, which of the following reactions is spontaneous:

(5.a) 2 H₂S(g) + 3 O₂(g) → 2 H₂O(g) + 2 SO₂(g)

(5.b) SO₂(g) + H₂O₂(ℓ) → H₂SO₄(ℓ)

(5.c) S(g) + O₂(g) → SO₂(g)

You must determine whether a given reaction (i) is exothermic or endothermic, (ii) has a positive or negative entropy, and (iii) if a given reaction is spontaneous only at low temperature or only at high temperature, or at all temperatures.

This year Burchard Company sold 29,000 units of its only product for $19.20 per unit. Manufacturing and selling the product required $114,000 of fixed manufacturing costs and $174,000 of fixed selling and administrative costs. Its per unit variable costs follow. Material $ 3.40 Direct labor (paid on the basis of completed units) 2.40 Variable overhead costs 0.34 Variable selling and administrative costs 0.14 Next year the company will use new material, which will reduce material costs by 70% and direct labor costs by 30% and will not affect product quality or marketability. Management is considering an increase in the unit selling price to reduce the number of units sold because the factory’s output is nearing its annual output capacity of 34,000 units. Two plans are being considered. Under plan 1, the company will keep the selling price at the current level and sell the same volume as last year. This plan will increase income because of the reduced costs from using the new material. Under plan 2, the company will increase the selling price by 30%. This plan will decrease unit sales volume by 15%. Under both plans 1 and 2, the total fixed costs and the variable costs per unit for overhead and for selling and administrative costs will remain the same. Required: 1. Compute the break-even point in dollar sales for both (a) plan 1 and (b) plan 2. (Round "per unit answers" and "CM ratio" percentage answer to 2 decimal places.)

Single Plantwide and Multiple Production Department Factory Overhead Rate Methods and Product Cost Distortion

The management of Firebolt Industries Inc. manufactures gasoline and diesel engines through two production departments, Fabrication and Assembly. Management needs accurate product cost information in order to guide product strategy. Presently, the company uses a single plantwide factory overhead rate for allocating factory overhead to the two products. However, management is considering the multiple production department factory overhead rate method. The following factory overhead was budgeted for Firebolt:

Direct labor hours were estimated as follows:

In addition, the direct labor hours (dlh) used to produce a unit of each product in each department were determined from engineering records, as follows:

a. Determine the per-unit factory overhead allocated to the gasoline and diesel engines under the single plantwide factory overhead rate method, using direct labor hours as the activity base.

b. Determine the per-unit factory overhead allocated to the gasoline and diesel engines under the multiple production department factory overhead rate method, using direct labor hours as the activity base for each department.

c. Recommend to management a product costing approach, based on your analyses in (a) and (b).

Management should select the ___________ factory overhead rate method of allocating overhead costs. The __________ factory overhead rate method indicates that both products have the same factory overhead per unit. Each product uses the direct labor hours __________. Thus, the __________ rate method avoids the cost distortions by accounting for the overhead __________.
