This Code Is Supposed To Be Performed In JAVA

1.) Create an abstract class DiscountPolicy. It should have a single abstract method computeDiscount that will return the discount for the purchase of a given number of a single item. The method has two parameters, count and itemCost. Create a driver class that tests this class and provide the UML.

2.) In a separate program, define DiscountPolicy as an interface instead of the abstract class. Create a driver class that tests this class and provide the UML.

Perform The Following

1.) Create an abstract class DiscountPolicy with a single abstract method computeDiscount that will return the discount for the purchase of a given number of a single item.

2.) Create a driver class

3.) Create an interface class DiscountPolicy with a single abstract method computeDiscount that will return the discount for the purchase of a given number of a single item.

4.) Create a driver class or use the same driver class that you created earlier

1. Enhance Binary System Conversion program with Lab05.2 Addition Function Write a program that accepts two positive binary number in string and perform the addition with Lab05.2 function enhance in a way can accept binary string in addition to decimal string (use input parameter to control the base2 or base10 addition) and output the as binary string. (Optional: Demonstrate 8 bits and 16 bits in length as inputs.) // the example function prototype for addition function below where accepting two numbers, m, and base as input; output the addition result as string type as return value; base should be 2 or 10 as required. string addFunction(string numberA, string numberB, int m, int base); Requirement: C++ programing; program an addition algorithm function that can both accept binary and decimal addition; convert each other if necessary. ................................................................................................................................................................................................................

Requirement:

Use the substitution method to prove the solutions for the following recurrences:

1. Research starting an online business selling goods. What are at least 5 things you need to make sure you understand before selling your first item online to be compliant with regulations? Explain each one of these and why they are important; including examples/scenarios.

1. Suppose you request a webpage that contains 10 images. Suppose the transmission time for a webpage is 10ms, and the transmission time for an image is 5ms. Suppose that 10 images are located on 3 different servers: 5 of them are saved on marist.edu with the webpage, 2 are saved on nyu.edu, and 3 are saved on albany.edu.

Suppose the RTT between your host and marist.edu is 10 ms, between your host and nyu.edu is 20 ms, and between your host and albany.edu is 30 ms.

Assume parallel transmissions are not considered in this problem, that is, objects are obtained one after another.

a) How long does it take to load the entire webpage with HTTP 1.0?

b) How long does it take to load the entire webpage with HTTP 1.1?

In java. Determine the value of each of the following expressions. (Format your answer with two decimal places.) a. Math.abs(-4) b. Math.abs(10.8) c. Math.abs(-2.5) d. Math.pow(3.2, 2) e. Math.pow(2.5, 3) f. Math.sqrt(25.0) g. Math.sqrt(6.25) h. Math.pow(3.0, 4.0) / Math.abs(-9) i. Math.floor(28.95) j. Math.ceil(35.2)

1. [15] Create a program called StreamingWords.java that modifies the StreamingIntegers.java from Task 1. The program should be able to do the following: JAVA

   1. accepts user input. User inputs can be under the following forms:

      1. one or more words, separated by white space.

      2. User can provide multiple inputs (each input is completed after user hits Enter)

      3. To stop inputting data, user will enter END then hit Enter.

   2. reads inputs from users into a queue data structure. Each data element in the queue contains one sentence (from whence user starts typing until they hit Enter)

   3. Once users finish entering input (END has been read), the program should begin remove the queue from the front, printing out the data elements in the queue.  

   4. The data elements should be printed out already sorted based on the number of words each element contains, regardless of the order of arrival or the total length of the characters. Each data element is to be printed on one line, and words within a data element are separated by a single white space.

A program called i2b.c was implemented with the intention to provide a binary representation of an integer. Unfortunately, the implementation has the following limitation:

• It was hard-coded to only convert a single number.
• The conversion algorithm only works for positive number.

Modify the existing source code of i2b.c such that:

• i2b.c can now accept a single command line argument. This command line argument is assumed to be a valid signed integer.
• i2b.c will convert the command line argument into its corresponding binary representation with the following condition:
  • The representation is an array of integers.
  • This array has a length of 32.
  • This array contains the binary representations of the integer argument.
  • Index 0 contains the most significant bit, and index 31 contains the least significant bit.
• i2b.c will print out the final binary representation on a single line without any space between the bits.

PROGRAM BELOW

#include <stdio.h>

#define N 32

int main(int argc, char *argv[]) {

  int n = 12345;

  int binRep[N];

  int i;

  for (i = 0; i < N; i++) {

    binRep[i] = 0;

  }

  i = 0;

  while (n > 0) {

    binRep[i] = n % 2;

    n = n / 2;

    i++;

  }

  for (i = N - 1; i >= 0; i--) {

    printf("%d", binRep[i]);

  }

  printf("\n");

  return 0;

}

Create a console application named TakeHomePay.cs under your homework directory (please refer to the earlier recorded Zoom sessions if you are not sure how to do it) that calculates the take-home pay for an employee. The two types of employees are salaried and hourly. Allow the user to input the employee’s first and last name, id, and type. If an employee is salaried, allow the user to input the salary amount. If an employee is hourly, allow the user to input the hourly rate and the number of hours clocked for the week. For hourly employees, overtime is paid for hours over 40 at a rate of 1.5 of the base rate. For all employees’ take-home pay, federal tax of 18% is deducted. A retirement contribution of 10% and a Social Security tax rate of 6% should also be deducted. Use appropriate constants and decision making structures.

Working in a technical field can be confusing because of all the acronyms. For example, CPU means Central Processing Unit, HDMI means High-Definition Multimedia Interface, and SMART means Self-Monitoring Analysis and Reporting Technology. Wouldn’t it be nice if there was a way to translate all these acronyms automatically?

Create a new file named Translate.java that contains the following method:

public static String expandAll(String[] acronyms, String[] definitions, String text)

This method should replace every instance of an acronym in the text with its corresponding definition. For example, expandAll({"JMU", "CS"}, {"James Madison University", "Computer Science"}, "JMU CS rocks!") would return the string “James Madison University Computer Science rocks!”.

You may assume that the two arrays will be the same length. You may also assume that the text will be reasonable English with correct grammar. In particular, there will be only one space between each word. Each sentence will either end with a space or a newline character. Punctuation not at the end of the sentence will always be followed by whitespace (i.e., you should be able to handle “Hi, Mom” but you won’t have to handle “Hi,Mom”).

Be careful not to replace acronyms in the middle of a word. For example, the string “CS uses MACS!” should expand to “Computer Science uses MACS!”, not “Computer Science uses MAComputer Science!”. You might find it helpful to use a Scanner to process the string one word at a time.
