Build a class and a driver for use in searching your computer’s secondary storage (hard disk or flash memory) for a specific file from a set of files indicated by a starting path. Lets start by looking at a directory listing. Note that every element is either a file or a directory.
Introduction and Driver
In this assignment, your job is to write a class that searches through a file hierarchy (a tree) for a specified file. Your FindFile class will search a directory (and all subdirectories) for a target file name.
For example, in the file hierarchy pictured above, the file "lesson.css" will be found once in a directory near the root or top-level drive name (e.g. "C:\") . Your FindFile class will start at the path indicated and will search each directory and subdirectory looking for a file match. Consider the following code that could help you build your Driver.java:
String targetFile = "lesson.css";
String pathToSearch ="
C:\\WCWC"; FindFile finder = new FindFile(MAX_NUMBER_OF_FILES_TO_FIND);
Finder.directorySearch(targetFile, pathToSearch);
File Searching
In general, searching can take multiple forms depending on the structure and order of the set to search. If we can make promises about the data (this data is sorted, or deltas vary by no more than 10, etc.), then we can leverage those constraints to perform a more efficient search. Files in a file system are exposed to clients of the operating system and can be organized by filename, file creation date, size, and a number of other properties. We’ll just be interested in the file names here, and we’ll want perform a brute force (i.e., sequential) search of these files looking for a specific file. The way in which we’ll get file information from the operating system will involve no ordering; as a result, a linear search is the best we can do. We’d like to search for a target file given a specified path and return the location of the file, if found. You should sketch out this logic linearly before attempting to tackle it recursively.
FindFile Class Interface
FindFile(int maxFiles): This constructor accepts the maximum number of files to find.
void directorySearch(String target, String dirName): The parameters are the target file name to look for and the directory to start in.
int getCount(): This accessor returns the number of matching files found
String[] getFiles(): This getter returns the array of file locations, up to maxFiles in size.
Requirements
Your program should be recursive.
You should build and submit at least two files: FindFile.java and Driver.java.
Throw an exception (IllegalArgumentException) if the path passed in as the starting directory is not a valid directory.
Throw an exception if you've found the MAX_NUMBER_OF_FILES_TO_FIND and catch and handle this in your main driver. Your program shouldn't crash but rather exit gracefully in the unusual situation that we've discovered the maximum number of files we were interested in, reporting each of the paths where the target files were found.
The only structures you can use in this assignment are basic arrays and your Stack, Queue, or ArrayList from the previous homeworks. Do not use built-in data structures like Java's ArrayList. To accomplish this, put in the following constructor and method to your ArrayList, Stack, or Queue:
public ArrayList(Object[] input) { data = input;
numElements = input.length;
}
public Object get(int index) {
return data[index];
}

A Quicksort (or Partition Exchange Sort) divides the data into 2 partitions separated by a pivot. The first partition contains all the items which are smaller than the pivot. The remaining items are in the other partition. You will write four versions of Quicksort:
• Select the first item of the partition as the pivot. Treat partitions of size one and two as stopping cases.
• Same pivot selection. For a partition of size 100 or less, use an insertion sort to finish.
• Same pivot selection. For a partition of size 50 or less, use an insertion sort to finish.
• Select the median-of-three as the pivot. Treat partitions of size one and two as stopping cases.
As time permits consider examining additional, alternate methods of selecting the pivot for Quicksort.
Merge Sort is a useful sort to know if you are doing External Sorting. The need for this will increase as data sizes increase. The traditional Merge Sort requires double space. To eliminate this issue, you are to implement Natural Merge using a linked implementation. In your analysis be sure to compare to the effect of using a straight Merge Sort instead.
Create input files of four sizes: 50, 1000, 2000, 5000 and 10000 integers. For each size file make 3 versions. On the first use a randomly ordered data set. On the second use the integers in reverse order. On the third use the
integers in normal ascending order. (You may use a random number generator to create the randomly ordered file, but it is important to limit the duplicates to <1%. Alternatively, you may write a shuffle function to randomize one of your ordered files.) This means you have an input set of 15 files plus whatever you deem necessary and reasonable. Files are available in the Blackboard shell, if you want to copy them. Your data should be formatted so that each number is on a separate line with no leading blanks. There should be no blank lines in the file. Even though you are limiting the occurrence of duplicates, your sorts must be able to handle duplicate data.
Each sort must be run against all the input files. With five sorts and 15 input sets, you will have 75 required runs.
The size 50 files are for the purpose of showing the sorting is correct. Your code needs to print out the comparisons and exchanges (see below) and the sorted values. You must submit the input and output files for all orders of size 50, for all sorts. There should be 15 output files here.
The larger sizes of input are used to demonstrate the asymptotic cost. To demonstrate the asymptotic cost you will need to count comparisons and exchanges for each sort. For these files at the end of each run you need to print the number of comparisons and the number of exchanges but not the sorted data. It is to your advantage to add larger files or additional random files to the input - perhaps with 15-20% duplicates. You may find it interesting to time the runs, but this should be in addition to counting comparisons and exchanges.
Turn in an analysis comparing the two sorts and their performance. Be sure to comment on the relative numbers of exchanges and comparison in the various runs, the effect of the order of the data, the effect of different size files, the effect of different partition sizes and pivot selection methods for Quicksort, and the effect of using a Natural Merge Sort. Which factor has the most effect on the efficiency? Be sure to consider both time and space efficiency. Be sure to justify your data structures. Your analysis must include a table of the comparisons and exchanges observed and a graph of the asymptotic costs that you observed compared to the theoretical cost. Be sure to justify your choice of iteration versus recursion. Consider how your code would have differed if you had made the other choice.

The necessary conditions and procedures needed to accomplish this assignment is given below. Quicksort is an algorithm used to sort data in a fast and efficient manner.
What is the Quicksort?Some rules to follow in the above work are:
A)Choose the initial element of the partition as the pivot.
b) Utilize the same method to select the pivot, but switch to insertion sort as the concluding step for partitions that contain 100 or fewer elements.
Lastly, Utilize the same method of pivot selection, but choose insertion sort for partitions that are of a size equal to or lesser than 50 in order to accomplish the task.

And office now has a total of 35 employees 11 were added last year the year prior there was a 500% increase in staff how many staff members were in the office before the increase
Answers
There were 5 staff members in the office before the increase.
To find the number of staff members in the office before the increase, we can work backward from the given information.
Let's start with the current total of 35 employees. It is stated that 11 employees were added last year.
Therefore, if we subtract 11 from the current total, we can determine the number of employees before the addition: 35 - 11 = 24.
Moving on to the information about the year prior, it states that there was a 500% increase in staff.
To calculate this, we need to find the original number of employees and then determine what 500% of that number is.
Let's assume the original number of employees before the increase was x.
If we had a 500% increase, it means the number of employees multiplied by 5. So, we can write the equation:
5 * x = 24
Dividing both sides of the equation by 5, we find:
x = 24 / 5 = 4.8
However, the number of employees cannot be a fraction or a decimal, so we round it to the nearest whole number.
Thus, before the increase, there were 5 employees in the office.

4.15 LAB: Mad Lib - loops
Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways.
Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows.
Ex: If the input is:
apples 5
shoes 2
quit 0
the output is:
Eating 5 apples a day keeps you happy and healthy.
Eating 2 shoes a day keeps you happy and healthy
Answers
Answer:
Explanation:
import java.util.Scanner;
public class MadLibs {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String word;
int number;
do {
System.out.print("Enter a word: ");
word = input.next();
if (word.equals("quit")) {
break;
}
System.out.print("Enter a number: ");
number = input.nextInt();
System.out.println("Eating " + number + " " + word + " a day keeps you happy and healthy.");
} while (true);
System.out.println("Goodbye!");
}
}
In this program, we use a do-while loop to repeatedly ask the user for a word and a number. The loop continues until the user enters the word "quit". Inside the loop, we read the input values using Scanner and then output the sentence using the input values.
Make sure to save the program with the filename "MadLibs.java" and compile and run it using a Java compiler or IDE.

As citizens online or in real life, how, or why, do the choices we make, almost always seems to have an effect (positive or negative) on others?
Answers
Answer:
The choices we make as citizens online or in real life have both positive and negative effects on others because we are social beings, who live in an interconnected world. Every choice has some consequences on the decision maker or on others. We make the choices, but the consequences follow natural laws, which we cannot control. When Adam and Eve chose to disobey God, human beings down the ages lost their innocence and freedom. When the Nazis chose to purify their race of European Jews, there was the Holocaust between 1941 and 1945. When the Minneapolis police officer chose to slaughter George Floyd in cold blood, violent protests erupted throughout the U.S.
Another current example to buttress this is the ravaging coronavirus pandemic, which originated in Wuhan - China. When the Chinese Communist government chose to suppress the information about the virus as it usually does, the aftermath is the thousands of dead humans all over the world, the economic downturn, loss of jobs, virus infections with other public health side effects, plus many other untold consequences.
Had the Chinese government made a different choice, the virus could not have spread worldwide as it had. Similarly, some citizens online choose to circulate unverifiable ("fake news") information. Many people have been misled by their antics, some have lost their lives, while many others live in perpetual bigotry and hatred. All these are because of individual choices.
Explanation:
Choice is a concept in decision making. It is the judging of the merits of multiple options so that one or some of the options are selected. When a voter votes for one candidate against others, she has made a choice (decision). Of course, choices have consequences, which we must live with. Choices also define our present and our future.
