Document Summary

The different forms of voting in australia and their strengths and weaknesses > Members of the hor represent single member electorates, which refers to the fact that just one member is elected by a constituency. There are different options for electing members this way. First-past-the-post = a first-past-the-post electoral system is one in which voters indicate on a ballot the candidate of their choice, and the candidate who receives the most votes wins. Second ballot = the voter casts a single vote for their chosen candidate. Preferential voting = the voter is required to number all boxes in the hor. The first preferences are counted, if a candidate has more than 50% they win the seat. If this is not achieved, the vote candidate with the fewest votes in eliminated and their second preferences are distributed amongst the remaining candidates. One member = easier to hold them accountable for their actions. Preferential voting to mitigate first past the post.

Question 4. [4 MARKS] You decide to save all your passwords in files, one password per file. You then decide you want to update your 6-character UTORid password, but you don't remember which of your password files you saved it in. Luckily, this is the only 6-character password you have so you decide to write a function to find the password and change it. Your code runs, but the function's body contains four bugs which will result in the function execution not matching its docstring description. In the space provided, rewrite the buggy lines with the bugs fixed. Do not add or remove any lines. def change password(files_list, new-password): " (list of str, str) -> str Preconditions: (1) files list is not empty.

(4) Your 6-character password is guaranteed to be in one of these files. In the appropriate file from files_list, replace your 6-character password with new-password, and return your old password. #Code If you think a given line contains a bug, rewrite it.

JAVA Coding Needed

6-Your program MUST be very modular

7-Your output MUST friendly (using labels for all info accordingly) and do display all input and calculated fields.

8-You must implement JOptionPane for all your input and output and must validate all input for all prompts.

Problem’s specifications:

The GPMS (Green Pollution Monitoring Service ) a fictitious orgaism is tasking you with the coding of an application that monitors the pollution levels of different sites in the USA.

All data are to be stored in an array of 100 object of type ‘Site’

Code a class ‘Site’ with the following attributes and methods:

-the ID of a given site.

-The name of a given site

-the pollution numeric value: adopt data and attributes from the following site

-Index value (see below under option 2 in the menu)

What to do?

-In the main class, declarae an array of 100 object of type ‘Site’

-In the main class, code the following menu in a separate function:

---------

-1-Add a site

-2-Display a site

-3-Quit

-If user select 1 from the MENU, constract an object site, and call a method in the class ‘Site’ that input data for a given site.

-If user select 2 from the MENU, call a function that search for a site in the array of objects of type ‘Site’ by ID and if found call a function that determines the index value (1 for good, 2 for moderate, 3 for unhealthy for sensitive groups, 4 for unhealthy, 5 for very unhealthy, 6 for hazardous) based on the pollution numerical value as represented in the given site.

-Call a function member of the class Site, that displays a report about this site (ID, Name, Pollution Value, Index Statement based on the index numerical value)

-Code a function/routine that after the user complete the input of all available sites, displays the site info. that is the most polluted. Also, display how many sites were input for this study.

What to submit?

Submit your complete .Java code named HW3_lastname.java

Extra credits:

-Use ArrayList instead of array of objects

His assignment is the next step to enhance your Programming Project 1 and Homework 3 works. As for
now, you can keep the inventory in a file and upload it to the array available for your program. You have
three classes for each type of products. It is time to think about how to improve the data model – all
three types have enough in common to be child classes of one parent class.
Thus, the first thing to do is create a superclass and make three product type classes subclasses. Then,
move as many members (fields and methods) from Type X, Y, and Z product classes to a superclass as
possible. Change the constructors appropriately.
The advantage of inheritance is the ability to create an array of superclass objects to be filled with
objects of different subclasses. Thus, your inventory is in one array. Use the product’s index in the array
to build the product’s ID (I would recommend starting with 1). In the superclass, create a static variable
that holds the number of products available in the inventory. It must grow as reading from the file
progresses.
Override a default toString() method for a superclass such that it shows product ID, name, regular
price, and type.
At this moment, make sure that all modifications you have made keep your application alive and
working.
The next step is to add three new classes to the project:
• Create a class to represent the user – hardware store customer. You must decide what members
this class needs. Ask the user to input necessary information.
• You may notice that the date of the year is a complicated piece of data. Create a class Date that
converts a string of the form of “mm/dd/yyyy” into an object with three fields – month, day, and
year. The class constructor may do this job, but do not forget to check the string for correctness.
Once you have this class ready, input the date as a string with the following converting into an
object of type Date. Remember, if you read a string from the keyboard after a number, you
may need to handle the new line symbol left in the input buffer.
• The result of your application is an order that must have the customer’s information, the date,
the product information, and the total amount to pay. Thus, the third class to add is the class
Order. When all the information is collected, the order is ready to be created and printed out.
Outputting the order is the primary behavior of an object of type Order, and it is the final step
of your application. Thus, class Order aggregates the customer’s info, date, product info, and
total. Please note that Type X and Type Y products need only regular price and amount to
calculate the total, while Type Z products must also consider the date.
The input and output examples for Types Y and Z are

Program requirements
The program must have one superclass and three subclasses for three types of products according to
the description given in Programming Project 1.
The program must read the inventory from the file into one array for all three types of products. Each
element of the array must be an object of one of the subclasses according to the information in the file.
Product ID must be formed automatically using a static variable.
The user must be registered in the system, and the corresponding object must be created. Then, the
user chooses a product from the list, specifies an amount and the date of planned purchasing.
The date, user, product, amount, and the total must be aggregated in an object of type Order and
outputted.
For this assignment, it is sufficient to output the order to the console. However, additional saving the
order in the file will be considered as a plus.
The test plan must be developed for the program. Consider and test different inputs that may cause
errors: incorrect file records, wrong date format, invalid user’s choice.
You have four weeks and three submission attempts for this assignment. Here is the suggested scenario
on how to plan your work:
