Exercise 2: Solve the programming exercise P10.19 on Page 536 on the book. Note: coin class provided in the Моodle. Write a program that reads in a set of coin descriptions from a file. The input file has the format coinNamel coinValuel coinName2 coinValue2 Add a method void read (Scanner in) throws FileNotFoundException to the Coin class of Section 7.2. Throw an exception if the current line is not properly formatted. Then implement a method static ArrayList readFile (String filename) throws FileNotFoundException In the main method, call readFile. If an exception is thrown, give the user a chance to select another file. If you read all coins successfully, print the total value.

The People class holds an unsorted list of humans. Initially, this list is empty. Existing Human objects may be added to the list using an insert method. Upon inserting a Human object, it is added to the array at the next available position and the position value in incremented. If the position value is equal to the size value, do not insert the Human. Instead, throw an exception that your driver can catch to print an error that the People object is full. Create a People class with the following features: Each People object has a statically allocated array of Human objects. Size attribute representing the maximum size of the array. Position attribute representing the next free position in the array. Default constructor with no arguments. Search method that takes a string argument and returns a Human object. This method returns the first Human object with a name matching the string argument. In other words, pass the name of a Human as a string, search the list of humans for…
Code on phyton: Write a program that accepts an amino acid sequence. The outshould should be able to display the peptide fragments wherein this was obtained using the enzyme called chymotrypsin. Note that: This enzyme should cleave the carboxyl side of Phenylalanine, Tyrosine, and Tryptophan. Also remember that there is an exception to the rule when it comes to Proline. Output should be like this: Enter Amino Acid Sequence: MQKESLWARYLEIFVGNFPYL The peptide fragment/s are: MQKESLW ARY LEIF VGNFPY L
Create a file named Question.py and then create a class on it named Question. A Question object will contain information about a trivia question. It should have the following: A constructor, with the following parameters: 1 string to be the question itself (for example: "When was Cypress College Founded?"). A list of four strings, each a possible answer to the question (only one of them should be correct) An integer named 'answer': the index in the list of the correct answer. Example: if the third answer in the answer list is the correct one, the client should pass 2 to this parameter to signify the correct answer is in index 2. Overload the __str__ method. It should return a string made up of the question and the four possible answers. A ‘guess’ method, with an integer parameter. If the 'answer' attribute matches the int passed to 'guess', return True. Otherwise, False On Main.py, in your main function, create a list and add four Question objects to it. You may give them with…

def analyze_file (filename: str, pos_words: List [str], neg_words: List [str]) -> Given the name of a file, a list of positive words (all in lowercase), and a list of negative words (all in lowercase), return some interesting data about the file in a tuple, with the first item in the tuple being the positivity score of the contents of this file, and the rest of the item: being whatever else you end up analyzing. (Helper functions are highly encouraged here.) How to calculate positivity score: For every word that is pos itive in the file (based on the words in the list of positive words) add 1 to the score. For every negative word (based on the list of negative words), subtract 1 from the score. Any neutral words (those that do not appear in either list) do not affect the score in any way. pass
For this assignment you are requested to write a program for the following scenario: • Build a program for a market, in the market we have items and each contains of three values (Item Name, Item Price, Item Expire Date). • The item values comes from a file each specification of the item is separated by (: ). • Must put the products that comes form the file into an array of object. • The program must check each product expire date if there is any products that expires in one month should notify the user as the output. • The expire checker process must be done on the array of object not directly from the file. NOTE: you can add only the month of the expiration date instead of adding full date (coffee:5000:August) and you can enter April as current month and then check the expiration.
msleep**** For this assignment, you must name your R file msleep.R (using Rstudio) For all questions you should load tidyverse. You should not need to use any other libraries. Load tidyverse with suppressPackageStartupMessages(library(tidyverse)) The actual data set is called msleep Round all float/dbl values to two decimal places. If your rounding does not work the way you expect, convert the tibble to a dataframe by using as.data.frame() All statistics should be run with variables in the order I state E.g., “Run a regression predicting mileage from mpg, make, and type” would be: lm(mileage ~ mpg + make + type...) Before attempting to answer these, or if you lose points upon an attempt, please review all CodeGrade information provided in the CodeGrade overview submodule - if you do not you are likely to lose points. What is the variance in total sleep for carni vores and those whose conservation status is lc? Your answer should be in a 1 X 1 data frame with a value…
One common use of a hash table is to build a glossary, or dictionary, of terms.In this section, we demonstrate one way to use a hash table for just such ause—a computer terms glossary.The program works by first reading in a set of terms and definitions from atext file. This process is coded in the BuildGlossary subroutine. The structureof the text file is: word,definition, with the comma being the delimiter betweena word and the definition. Each word in this glossary is a single word, but theglossary could easily work with phrases instead. That’s why a comma is usedas the delimiter, rather than a space. Also, this structure allows us to use theword as the key, which is the proper way to build this hash table.Another subroutine, DisplayWords, displays the words in a list box so theuser can pick one to get a definition. Since the words are the keys, we can usethe Keys method to return just the words from the hash table. The user canthen see which words have definitions.To retrieve a…

/*TASK 5. Implement part 1 of the report. You need to read data from input.txt file, store it into array of items (called items) and write it in a formatted form to the output file. Code, debug and present it in the best possible format.
