Consider the following: abstract class WashingMachine { public WashingMachine() { // Code to initialize the class goes here. } abstract public void Wash(); abstract public void Rinse(int loadSize); abstract public long Spin(int speed); } class MyWashingMachine extends WashingMachine { public MyWashingMachine() { // Initialization code goes here. } public void Wash() { // Wash code goes here. } public void Rinse(int loadSize) { // Rinse code goes here. } } What is wrong with the myWashingMachine class Which of the following are good candidates for instance variables for a class that you would define?
a. Private data whose values could be different for different objects of the class.
b. Constants used by the class and the client. Variables whose values are shared by all class objects.
c. Variables (like loop counters or temporary variables) used by most or all of your instance methods (in an attempt to avoid redeclaring these variables multiple times as locals for each instance method).

Write a function processpeople() that takes the name of a file as a parameter. each line of the file corresponds to information about a person. in particular a line contains either a name (in the form lastname, firstname with no spaces in it) or a name (lastname, firstname) and a year. the function will process the file, creating a person object for each line in the file. the function will print information about each line as it processes it, as well as appending the new person object into a list. make sure to use person methods to display information rather than recreating the work you did for the first problem. once the entire file has been processed, the function returns the list of person objects created from the file. if the file is empty, the function should return an empty list. if the input file cannot be opened, the function should print a message to that effect and then return an empty list. the following shows what would be displayed for two example files which have been provided in the link. the file none. txt does not exist. note that your function must work on an arbitrary file that consists of valid lines. you cannot assume anything about the file except that it contains lines that have the format described above.

Dameas communication challenge is due to which factor

Jason, samantha, ravi, sheila, and ankit are preparing for an upcoming marathon. each day of the week, they run a certain number of miles and write them into a notebook. at the end of the week, they would like to know the number of miles run each day, the total miles for the week, and average miles run each day. write a program to them analyze their data. your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. furthermore, your program must contain at least the following functions: a function to read and store the runners’ names and the numbers of miles run each day; a function to find the total miles run by each runner and the average number of miles run each day; and a function to output the results. (you may assume that the input data is stored in a file and each line of data is in the following form: runnername milesday1 milesday2 milesday3 milesday4 milesday5 milesday6 milesday7.)
