Bonus quiz question:V Please do not modify the methods' headers.V Complete the TWO functions below such that the list is written to XML. The code should only write objects of typeXbox. You may implement an Xbox class to help you test your code.V The first function MUST use non-Java Stream operations (FOR, WHILE .)V The second function MUST use Java Stream operations only (map, filter, forEach ...) without the use of anyconditional operations like IF, SWITCH, TURNARY ..private static void serializeToXML_Iterative(final List list, final String xmlFile) {// Use loops, don't use Java Streams}private static void serializeToXML_Streams(final List list, final String xmlFile) {// Use Java Streams ONLY, don't use loops or conditional operations}

astfoodStats Assignment Description For this assignment, name your R file fastfoodStats.R For all questions you should load tidyverse, openintro, and lm.beta. You should not need to use any other libraries. suppressPackageStartupMessages(library(tidyverse)) suppressPackageStartupMessages(library(openintro)) suppressPackageStartupMessages(library(lm.beta)) The actual data set is called fastfood. Continue to use %>% for the pipe. CodeGrade does not support the new pipe. Round all float/dbl values to two decimal places. 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...) To access the fastfood data, run the following: fastfood <- openintro::fastfood Create a correlation matrix for the relations between calories, total_fat, sugar, and calcium for all items at Sonic, Subway, and Taco Bell, omitting missing values with na.omit().

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.

Might there be a way to directly access commonly used operators, such as the arithmetic operators or the stream operators, with enumeration types? For example, would overloading these operators be a good solution? Why or why not?
1. A list of students (student ID, first name, last name, list of 4 test grades) will be transformed intoStudent objects. We will provide this file for you.a. Each feature will be separated by commas, however; the grades will be separated byspaces, as shown in this example line: 82417619,Erik,Macik,95.6 85 100 88[Hint: It seems like you might need to use the split method twice]b. Your program should work with any file with any number of lines.2. A menu will be displayed on loop to the user (meaning after a user completes a selection, themenu will be displayed again, unless the user exits).The menu options should be the following:a. View Student Grade and Averageb. Get Test Averagec. Get Top Student per examd. Exit3. Your system shall incorporate the following classes. Each class will require one file.GRADE CALCULATORPurposeA class that contains useful methods that can be used to calculate averages andconvert grades to letter gradesAttributes: NoneMethodsconvertToLetterGrade(double…

1. The append() method concatenates the string representation of any other type of data tothe end of the invoking StringBuffer object. It has several overloaded versions. Here are afew of its forms:StringBuffer append(String str)StringBuffer append(int num)StringBuffer append(Object obj)2. The result is appended to the current StringBuffer object.3. The buffer itself is returned by each version of append( ).4. This allows subsequent calls to be chained together, write java code for it
