write a java code to implement a linked list, called CupList, to hold a list of Cups.

1.Define and write a Cup node class, called CupNode, to hold the following information about a cup:

•number (cup number)

•capacity (cup capacity in ml)

•Write a method size() that returns the number of elements in the linkedlist CupList.

•Write a method getNodeAt() that returns the reference to cup node object at a specific position given as a parameter of the method.

•Write a method, insertPos(),  to insert a new CupNode object at a specific position given as a parameter of the method.

•Write a method, deletePos(),  to remove the CupNode object at a specific position given as a parameter of the method.

•Write a method, swapNodes,  to swap two nodes at two positions pos1 and pos2 given as parameters of the method.

Implement the Cup list using double linked list.

•Update CupNode class by adding a link to the previous node in the list. Then update the constructor of the class

•Update the CupList by adding a last attribute, to hold the reference to the last node of the list.

•Implement the following methods in CupList isEmpty(), size(), insertAtFront(), insertAtRear(), insertAt(), removeFirst(), removeLast(), removeAt().

  CupNode should have a constructor and methods to manage the above information as well as the link to next node in the list.

2.Define and write the CupList class to hold objects of the class CupNode. This class should define:

a)a constructor,

Rock, Paper, Scissors

Introduction

In this assignment you will create a program that will simulate the popular children’s game “Rock, Paper, Scissors”; using only Boolean logic and practice using the for-loop and logical operators as well as continue getting used to data of various types.

Skills: string input/output, data types, logical operators, and control structures

Rock-Paper-Scissors

Rock-Paper-Scissors is a game where two players, on the count of 3, show the rock/paper/scissors symbol with their hand. Rock smashes scissors, scissors cuts paper, and paper covers rock:

Once both players have played valid gestures, there are two ways to determine the winner: one using string comparison and Boolean logic and the other using modular arithmetic; you’ll write a solution using both approaches. For this assignment, only “rock”, “paper”, and “scissors” are considered valid gestures.

Definitions:

1. Valid game: a game in which both players select a valid gesture

2. Invalid game: a game in which a player selects a gesture that is not “rock”, “paper”, or “scissors”. (HINT: DeMorgan’s law will help negation of valid game)

main.cpp

Your program should use a for-loop to play 7 consecutive games (must be a variable) of Rock-PaperScissors determining the winner using only the four decision statements. For each game, your program should:

1) Prompt Player 1 for their selection. The inputs for each game are given below. a. If Player 1 enters an invalid selection you should update the count of invalid games and then begin a new game.

2) Prompt Player 2 for their selection. The inputs for each game are given below.

a) If Player 2 enters an invalid selection you should update the count of invalid games and then begin a new game.

3) If both players have selected a valid gesture determine the winner using string comparison and if/else logic.

4) For each valid game completed, update the count of the number of wins by Player 1, the number of wins by Player 2, or the number of ties as needed.

Test input:

• Game 1: Player one plays “scissors” and Player 2 plays “paper”

• Game 2: Player 1 plays “paper” and Player 2 plays “papers”

• Game 3: Player 1 plays “rock” and Player 2 plays “rock”

• Game 4: Player 1 plays “rocks”

• Game 5: Player 1 play “paper” and Player 2 plays “scissors”

• Game 6: Player 1 plays” scissors” and Player 2 plays “rock”

• Game 7: “Player 1 plays “paper” and Player 2 plays “rock”

Test Run: Your code should look exactly like the one below

Player 1 Enter Selection: scissors

Player 2 Enter Selection: paper

Player 1 Enter Selection: paper

Player 2 Enter Selection: papers

Player 1 Enter Selection: rock

Player 2 Enter Selection: rock

Player 1 Enter Selection: rocks

Player 1 Enter Selection: paper

Player 2 Enter Selection: scissors

Player 1 Enter Selection: scissors

Player 2 Enter Selection: rock

Player 1 Enter Selection: paper

Player 2Enter Selection: rock

In this assignment, you will create a Java program to search recursively for a file in a directory.

• The program must take two command line parameters. First parameter is the folder to search for. The second parameter is the filename to look for, which may only be a partial name.

• If incorrect number of parameters are given, your program should print an error message and show the correct format.

• Your program must search recursively in the given directory for the files whose name contains the given filename. Once a match is found, your program should print the full path of the file, followed by a newline.

• You can implement everything in the main class. You need define a recursive method such as: public static search(File sourceFolder, String filename) For each folder in sourceFolder, you recursively call the method to search.

• A sample run of the program may look like this: //The following command line example searches any file with “Assignment” in its name

Hi please tell me what to input exactly, thanks

Requirements: The company that needed the flowchart and pseudocode for calculating the final price of the TV set and sound bar has given you the responsibility of creating a program for that purpose. The requirements remain the same as those indicated for the flowchart: The program will be used to enter the price of the TV set and the sound bar, in that order. The place of residence will also be entered in order to calculate the sales tax Residents of New Jersey pay 6.625% sales tax Residents of New York City pay 8.875% sales tax. • Residents of New York State (outside New York City) pay 4.375% sales tax The place of residence will be entered as NJ, NYC or NYS After the calculation is performed, the final result will be displayed

In Python write a function with prototype “def wordfreq(filename = "somefile.txt"):” that will read a given file that contains words separated by spaces (perhaps multiple words on a line) and will create a dictionary whose keys are the words and the value is the number of times the word appears. Convert each word to lower case before processing.

Please solve me this question and send me the video clip how to do it

This problem contains loops, sorting arrays, random generation, and variable matching.

Include an analysis (data requirements) and algorithm in your reply.

Write a “lottery engine” program to simulate drawing lottery numbers. You will draw 7 numbers, randomly selected from 1 to 16.

a) Allow the user to enter their own selection of numbers first,

Example numbers: 2 3 7 9 10 11 15

b) then run your “lottery engine” to select the “winning numbers”. Numbers are drawn randomly.

Use the clock as the seed value for your random function (Hint: use “srand(clock());” ).

c) Be sure to remove duplicate entries.

d) Print out the draw result as it was generated (unsorted), then sort the array and print out the sorted numbers.

Example output:

“

Draw unsorted: 2 12 16 14 7 13 1

Draw sorted: 1 2 7 12 13 14 16

“

e) Then print out the matching numbers selected by the user:

f) Also print the sorted user selection and draw results and matching numbers to a TXT file called “Results.txt”.

Example output

“

Draw sorted: 1 2 7 12 13 14 16

User’s sorted: 2 3 7 9 10 11 15

Matching numbers: 2 – 7

Given an integer named area which represents the area of a rectangle, write a function minPerimeter that calculates the minimum possible perimeter of the given rectangle, and prints the perimeter and the side lengths needed to achieve that minimum. The length of the sides of the rectangle are integer numbers. For example, given the integer area = 30, possible perimeters and side-lengths are: (1, 30), with a perimeter of 62 (2, 15), with a perimeter of 34 (3, 10), with a perimeter of 26 (5, 6), with a perimeter of 22 Thus, your function should print only the last line, since that is the minimum perimeter. Some example outputs:

>>>minPerimeter(30)

22 where rectangle sides are 5 and 6.
