Answer:

Here is the corrected code:

import java.util.*;

public class DebugNine36 {  //class name

  public static void main(String[] args)    {  //start of main method

     ArrayList<String>products = new ArrayList<String>();  //creates an ArrayList of type String names products

     products.add("shampoo");  //add shampoo to product array list

     products.add("moisturizer");  //add moisturizer product array list

     products.add("conditioner");  //add conditioner product array list

     Collections.sort(products);  //sort the elements in products array list

     display(products);  //calls display method by passing products array list

     final String QUIT = "quit";  //declares a variable to quit the program

     String entry;  //declares a variable to hold product/element or quit

     Scanner input = new Scanner(System.in);  //creates Scanner object

     System.out.print("\nEnter a product or " + QUIT + " to quit >> ");  //prompts user to enter a product or enter quit to exit

     entry = input.nextLine();  //reads the entry value from user

     while(!entry.equals("quit"))       {  //loops until user enters quit

        products.add(entry);  //adds entry (product) to products array list

        Collections.sort(products);  //sorts the elements in products array list

        display(products);  //calls display method by passing products arraylist

        System.out.print("\nEnter a product or " + QUIT + " to quit >> ");  //keeps prompting user to enter a product or enter quit to exit

        entry = input.nextLine();        }    }  //reads the entry value from user

  public static void display(ArrayList products)    {  // method to display the list of products

     System.out.println("\nThe size of the list is " + products.size());  //displays the size of the array list named products

     for(int x = 0; x < products.size(); ++x)  //iterates through the arraylist products

        System.out.println(products.get(x));    }  } //displays each item/element in products array list

Explanation:

In the code the following statement are corrected:

1.

ArrayListproducts = new ArrayList();

This gave an error: cannot find symbol

This is corrected to :

 ArrayList<String>products = new ArrayList<String>();

2.

         products.add(shampoo);

         products.add(moisturizer);

         products.add(conditioner);

Here shampoo moisturizer and conditioner are String type items that are to be added to the products so these strings have to be enclosed in quotation marks.

This is corrected to :

     products.add("shampoo");

     products.add("moisturizer");

     products.add("conditioner");

3.

display();

This method is called without giving any arguments to this method. The method display takes an ArrayList as argument so it should be passed the arraylist products to avoid error that actual and formal argument lists differ in length .

This is corrected to :

display(products);

You have a large text file of people. Each person is represented by one line in the text file. The line starts with their ID number and after that, has the person's name. The lines are sorted by ID number in ascending order. There are n lines in this file. You write a search function that returns the name of a person whose ID number is given The simplest way to do that would be to program a loop that goes through each line and compares the ID number in the line against the given ID number. If there is a match, then it returns the name in that line. This is very inefficient, because the worst-case scenario is that this program needs to go through almost everyone the person we are looking for could be last. using the fact that he tli s sored wil greany speed up the processbus to use a birarysearch alkrhm We go to the middle line of the file first and compare the ID found there (P) to the given ID (Q). (f the number of lines is even, we go above or below the arithmetic middle.) if P=Q then our algorithm terminates . we have found the person we are looking for. If P is less than Q, that means that the person we are looking for is in the second half of the file. We now repeat our algorithm on the second half of the file. If P is greater than Q, that means that the person we are looking for is in the first half of the file. We now repeat our algorithm on the first half of the file.

Required:
Of what order is the worst-case number of comparison operations that needed for this algorithm to terminate?

We are designing a program that must do the following:
Read 3 integers from a file called "data.txt"
Sum the integers
Compute the mean of the integers
Output the mean to a file called "mean.txt".
We are required to select functions from the library provided below to complete our program. Inside of the main () function, fill in the correct C statements to satisfy the four requirements listed above. You must fill in all the lines labeled with "statement x", where x is 2, 3, 4, 5, or 6. The first statement has been completed for you.
// These are the library functions that we must invoke!
// Precondition: The input file must already be open.
int read_integer (FILE *infile)
{
int number = 0;
fscanf (infile, "%d", &number);
return number;
}

int calculate_sum (int number1, int number2, int number3)

{
int sum = 0;
sum = number1 + number2 + number3;
return sum;
}

double calculate_mean (int sum, int number)
{
double mean = 0.0;
mean = ((double) sum) / number;
return mean;
}
// Precondition: The input file must already be open.
void print_double (FILE *outfile, double number)
{
fprintf (outfile, "%0.2lf\n", number);
}
// Fill in the appropriate statements for main ().
#include
int main (void)
{
int n1 = 0, n2 = 0, n3 = 0, sum = 0;
double average = 0.0;
FILE *infile = NULL, *outfile = NULL;
// We will not check to see if files were opened successfully; assume they are
infile = fopen ("data.txt", "r");
outfile = fopen ("mean.txt", "w");
______n1 = read_integer (infile)_________________________ // statement 1

Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of objects repeatedly and determine how many picks are needed for all the objects to be picked at least once. A variation of the problem is to pick cards from a shuffled deck of 52 cards repeatedly and find out how many picks are needed before you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks needed to get total of four cards from each different suit and display the four cards picked (it is possible that a card may be picked twice). Here is a sample run of the program:
4 of Diamonds
8 of Spades
Queen of Clubs
8 of Hearts
Number of picks: 9

Assignment
Create an HTML form that will accept four fields: pet name, pet ID, pet weight, and birthdate. Name this file petInfo.html. There should be a submit and reset button on your html form. Your input fields for your form should be inside of a table. The submit button should send the data to a php file named updateInfo.php. The updateInfo.php file should check the data submitted by the html file for proper formatting. While it is allowable that you may check input on the client side (either HTML or Javascript), you MUST check for valid input on the server using PHP.
***IMPORTANT***
Your POST variables in your HTML file must be labeled as follows. I have written an automated script to run tests on your code, and it depends on the POST variables being labeled correctly within the HTML Form.
1) "pet_name"
2) "pet_id"
3) "pet_weight"
4) "birth_date"
The following rules must be enforced by your PHP script about the input.
• No field is allowed to be blank.
• Maximum length of pet name is 20 characters.
• Pet ID must be 4 lowercase letters followed by 3 numbers. Example: abcd123
• Max length of pet weight is 7 characters. Max of two digits after decimal point. Must be a positive value. Range: 0.00 – 9999.99.
• The name should be only made up of alphabetical characters. (no numbers or symbols).
• Birthdate should be in the format 1/1/2002. Examples of valid input: 01/01/2002, 12/1/1999, 12/25/2015. Do not allow: 12/25/02 (The whole year should appear in the input).
If all the fields are valid, your PHP script should save the data into a file named petInfo.txt which should have the following format, and be sorted by "pet_name". Put each record on its own line. To simplify things, you can assume that Names are unique - i.e. you can use the name as a key for your associative array. (I won't use two of the same name when I test your code).
PetName, PetID, PetWeight, PetBirthDate\n
Once the new data has been received, you should also display ALL data that has been entered into the text file from your PHP script into an HTML table. The table should be sorted by last name just like the text file. After successfully displaying your table, create a link back to the petInfo.html page.
