Task #3 Experimenting with an array of random integers (Week 2)
Make sure that the following 3 experiments are done repeatedly by generating a new set of integers to fill the array. For this iterate 10 times and observe results for consistency.
• Make the array size reasonably large (say a thousand) and an even number.
• Choose the version of nextInt() that allows you to set a cap on the random integers generated (set it to a few thousands, but way less than the maximum integer).
• Do the following experiments:
o Count how many integers in the array are odd and even. Are the odd and even counts almost equal?
o Find the minimum, maximum, and average of the integers in the array. Keep track of the minimum and maximum of the three quantities across runs.
o Sort the array by writing an inner and an outer loop. Count the number of times you needed to swap integers.

Using Java

Write only “stubs” for methods in the Figure, Rectangle, and Triangle classes:

Consider a graphics system that has classes for various figures — say, rectangles, boxes, triangles, circles, and so on. For example, a rectangle might have data members’ height, width, and either a center point or upper-left corner point, while a box and circle might have only a center point (or upper-right corner point) and an edge length or radius, respectively. In a well-designed system, these would be derived from a common class, Figure. In this homework assignment, you will implement such a system.

The class Figure is an abstract base class. In this class, create abstract methods for draw, erase, center, equals, and toString.

Add Rectangle and Triangle classes derived from Figure. Each class has stubs for methods erase, draw, and center. In these "stubs", the method simply prints a message telling the name of the class and which method has been called in that class. Because these are just stubs, they do nothing more than output this message. The method center calls the erase and draw methods to erase the object at its current location and redraw the figure at the center of the picture being displayed. Because you have only stubs for erase and draw, center will not do any real “centering” but simply will call the methods erase and draw, which will allow you to see which versions of draw and center it calls. Add an output message in the method center that announces that center is being called. The methods should take no arguments.

Define a demonstration program for your classes which contains main. Test your programs:

creating at least two Rectangle objects and two Triangle objects.
- All instantiated classes have an equals and toString methods because these are abstract in the Figure class.
- In this part of the homework, equals can simply return true, and toString can returns a String announcing that toString has been invoked.
"draw" all of the objects you just created
"center" at least one Rectangle and one Triangle object

In main, make sure that you tell the user what's going on at each step.

Your output should consist primarily of messages from your stub methods. An example of the output from your program might be the following (note: output from main method is shown below in italics):

  ** Create 2 triangles **
  Entering Figure Constructor for triangle 0
  Running Triangle constructor for triangle 0
  Entering Figure Constructor for triangle 1
  Running Triangle constructor for triangle 1

  ** Create 2 rectangles **
  Entering Figure Constructor for rectangle 0
  Running Rectangle constructor for rectangle 0
  Entering Figure Constructor for rectangle 1
  Running Rectangle constructor for rectangle 1

  ** Draw both triangles **
  Entering draw() method for Triangle 0
  Entering draw() method for Triangle 1

  ** Draw both rectangles **
  Entering draw() method for Rectangle 0
  Entering draw() method for Rectangle 1

  ** Center one triangle **
  Entering center() method for Triangle 0
  center() calling erase()
  Entering erase() method for Triangle 0>
  center() calling setCenter() to reset center.  
  Entering Figure's setCenter() for figure 0
  center() calling draw()
  Entering draw() method for Triangle 0

  ** Center one rectangle **
  Entering center() method for Rectangle 1
  center() calling erase()
  Entering erase() method for Rectangle 1
  center() calling setCenter()
  Entering Figure's setCenter() for figure 1
  center() calling draw()
  Entering draw() method for Rectangle 1

you are required to use only the functional features of Scheme; functions with an exclamation point in their names (e.g., set!) and input/output mechanisms other than load and the regular read-eval-print loop are not allowed. (You may find imperative features useful for debugging. That’s ok, but get them out of your code before you hand anything in.)

Problem: Implement a class named StringParser, along with specified methods, that can read words from a text file, parse those words (such as finding palindromes), and write those words to a new file More specifically: 1. Write the StringParser class so that it has the following methods: a) public static void main(String[] args) -- The main driver of the program. Prompts the user for an input file, an output file, and a choice for what kinds of words to output. b) public static void rawOutput(File in, File out)-- Parses an input file, writing each word from the input on a separate line in the output file. c) public static void palindromeOutput(File in,File out) -- Parses an input file, writing only the palindromes to the output file, in alphabetical order, one line at a time, without repetition. Palindromes are words that read the same forward and backward, ignoring digits and punctuation. d) public static void hundredDollarWordOutput(File in, File out) -- Parses an input file, writing only the $100 words to the output file, in alphabetical order, one line at a time, in uppercase, without repetition. $100 words are found by assigning $1 to A, $2 to B, and so on. For example ELEPHANTS is a $100 word because: E + L + E + P + H + A + N + T + S is 5 + 12 + 5 + 16 + 8 + 1 + 14 + 20 + 19 = 100 e) public static boolean isPalindrome(String word) -- Determines if a word is a palindrome (reads the same forward and backward). The method is case-sensitive, so it will say that dad and DAD and d-a-d are palindromes, but Dad and d-ad are not palindromes. f) public static String cleanup(String word)-- Takes a string and removes all non-letters, returning an all uppercase version. For example, this input: "A man, a plan, a canal. Panama." will produce this output: "AMANAPLANACANALPANAMA" g) public static int wordValue(String word)-- Returns the monetary value of a word, found by assigning the value $1 to A, $2 B, and so on, up to $26 for Z. The method will ignore differences in case, so both A and a are each worth $1. It will also ignore any non-letters in the input. 2. Create your own input test file, and use it with your code to generate three output files. 3. Upload all five files (Java source code, input file, three output files).

For this assignment, you will take on the role of software developer as part of a team of developers for a retail company. The payroll manager of the company has tasked you with developing a Java program (if you can put it in NetBeans that would be awesome) to quickly calculate an employee’s weekly gross and net pay. The program must prompt the user to enter the employee’s name, rate of pay, and hours worked. The output will display the information entered into the program along with the calculations for gross pay, total amount of deductions, and net pay.

In this coding assignment, you will utilize the Java syntax and techniques you learned while reviewing the required resources for Week 1. You may select appropriate variable names as long as proper Java syntax is used. You will also submit your source code.

Input:
In the input section, utilize Java syntax and techniques to input the employee’s name, rate of pay, and hours worked. The input should be completed either via keyboard or via file.

Processing:
In the processing section, the following calculations will need to be performed in the processing section:

Gross Pay:
Gross pay if hours worked are 40 hours or less = hours worked * rate of pay
Gross pay if hours worked are greater than 40 hours = ((hours worked – 40) * (rate of pay * 1.5)) + (40 * rate of pay)
- Example – Employee worked 55 hours. The employee’s rate of pay is $10.00.
  ((55 – 40) * (10 * 1.5)) + (40 * 10) = 625
  The gross pay is $625.
Deductions:
Deductions are calculated based upon the following rates:
- Federal Tax = 15%
- State Tax = 3.07%
- Medicare = 1.45%
- Social Security = 6.2%
- Unemployment Insurance = .07%

The following calculations are used to calculate each deduction:

Federal tax amount = federal tax rate* gross pay
State Tax amount = state tax rate * gross pay
Medicare amount = Medicare rate * gross pay
Social Security amount = social security rate * gross pay
Unemployment Insurance amount = unemployment insurance amount * gross pay

Total deductions = Federal Tax amount + State Tax amount + Medicare amount + Social Security amount + Unemployment Insurance amount

Net Pay:
The net pay amount is calculated as follows:
Net pay = gross pay amount – total deductions

Output:
The Java program should display the following information:

Employee Name
Rate of Pay
Hours Worked
Overtime Worked
Gross Pay
Total amount of deductions
Net Pay

In this assignment will demonstrate your understanding of the following:

1. C++ classes;

2. Implementing a class in C++;

3. Operator overloading with chaining;

4. Preprocessor directives #ifndef, #define, and #endif;

5. this – the pointer to the current object.

In this assignment you will implement the Date class and test its functionality.

Consider the following class declaration for the class date:

class Date

{

public:

Date(); //default constructor; sets m=01, d=01, y =0001

Date(unsigned m, unsigned d, unsigned y);

//explicit-value constructor to set date equal to today's

//date. Use 2-digits for month (m) and day (d), and 4-digits for year (y); this function should //print a message if a leap year.

void display();//output Date object to the screen

int getMonth();//accessor to output the month

int getDay();//accessor to output the day

int getYear();//accessor to output the year

void setMonth(unsigned m);//mutator to change the month

void setDay(unsigned d);//mutator to change the day

void setYear(unsigned y);//mutation to change the year

friend ostream & operator<<(ostream & out, const Date & dateObj);//overloaded operator<< as a friend function with chaining

//you make add other functions if necessary

private:

int myMonth, myDay, myYear; //month, day, and year of a Date obj respectively };

You will implement all the constructors and member functions in the class Date. Please see the comments that follow each function prototype in the Date class declaration above; these comments describe the functionality that the function should provide to the class.

Please store the class declaration in the file “date.h” and the class implementation in the file “date.cpp” , and the driver to test the functionality of your class in the file “date_driver.cpp”.

S A M P L E O U T P U T FORAssignment#2

Below I have provided a skeleton with stubs and a driver to help you get started. Remember to separate the skeleton into the appropriate files, and to include the appropriate libraries.

You should submit the files “date.h” , “date.cpp” , and “date_driver.cpp” together in a zip file named with the format “lastname_firstname_date.zip” to Canvas before the due date and time. Usually the tool you use to create a zip file will automatically append “zip” to the end of the filename.

Notes:

1. ALL PROGRAMS SHOULD BE COMPILED USING MS VISUAL STUDIO C++!

2. Information on Month: 1 = January, 2 = February, 3= March, …, 12 = December

3. Test the functionality of your class in “date_driver.cpp” in the following order and include messages for each test:

a. Test default constructor

b. Test display

c. Test getMonth

d. Test getDay

e. Test getYear

f. Test setMonth

g. Test setDay

h. Test setYear
