1. Design a Java CartesianPoint class for a Cartesian Point which implements both cloneable and comparable interfaces

The class should have the following private member variables:

• the x value of a point: int

• the y value of a point: int

and the class should have the following public member functions:

• default constructor which initializes the point to the origin of the Cartesian coordinate system

• explicit constructor which initializes the point to a pair of given value as (u, v) • setX() function, which sets the x value to a new value v

• setY()function, which sets the y value to a new value u

• whereX() function, which returns the x value

• whereY() function, which returns the y value

• Overrided compareTo()method: use the distance to the coordinate system’s origin for comparison

• Overrided clone() method.

Please write your complete CartesianPoint class and its testing class below

1a (35 pts) Write your complete Java code for the above Java class in CartesianPoint.java file. 1b (35 pts) In a new file named testPoint.java, write your test Java class and its main method which will do the following:

✓ create two Cartesian objects(pointOne, pointTwo), both of them with the explicit constructors;

✓ then compare the two points and output the farther away one’s x and y coordinates (test of comparable interface);

✓ next create a third CartesianPoint object pointThree which is a clone of the farther away one between the above two points, and then reset its coordinates to new x and y values and output them.

For a LinkedList in Java how do I

- Add a method named replace() that takes in two parameters (the data object to replaced, followed by the one to be inserted) that will remove the first occurrence of the item to be replaced and add the second parameter to the list. The method returns a boolean - true if the item to be replaced was found, false if not

- Add an instance method named showList() (no parameters or return value) that will extract all of the values from the list and display them in order, one per line, followed by another line displaying how many values are currently in the list. If the list is empty, display the message “The list is currently empty” instead

- Overload showList() with an integer parameter which represents how many items to display on each line. The method needs to newline after the last item no matter how many items were displayed (i.e. don’t leave the cursor hanging.)

(C++ with main to test)

2.2
Task 1
You are going to implement a variant of the standard linked list, the circular list. The
circular linked list is a variant of the standard linked list that wraps around so that
traversals through the list will wrap around to the beginning instead of simply reaching
the end. This will consist of implementing two classes: cLL and item.
2.2.1
cLL
The class is described according to the simple UML diagram below:
2cLL<T>
-head:item<T> *
-size:int
------------------------
+cLL()
+~cLL()
+isEmpty():bool
+getSize():int
+push(newItem: item<T>*):void
+pop():item<T>*
+getMaxItem():T
+getMinItem():T
+peek(): item<T> *
+printList():void
The class variables are as follows:
• head: The head pointer for the linked list.
• size: The current size of the circular linked list. It starts at 0 and grows as the list
does.
The class methods are as follows:
• cLL: The constructor. It will set the size to 0 and initialise head as null.
• ∼cLL: The class destructor. It will iterate through the circular linked list and
deallocate all of the memory assigned for the items.
• isEmpty: This function returns a bool. If the circular linked list is empty, then it
will return true. Otherwise, if it has items then it will return false.
• getSize: This returns the current size of the circular linked list. If the list is empty
the size should be 0.
• push: This receives a new item and adds it to the circular linked list. It is added to
the front of the list. The front being the head of the list.
• pop: This receives, and returns, the first element in the list. The first element is
removed from the list in the process. If the list is empty, return null. The first
element referring to the head pointer in this case.
• peek: This function returns the first element in the list but does not remove it, first
being the head item.
• getMaxItem: This will return the value of the item in the circular linked list which
is the maximum for the list.
• getMinItem: This will return the value of the item in the circular linked list which
is the minimum for the list.
3• printList: This will print out the entire list from head onwards. Importantly, each
item is listed on one line with commas delimiting each item. For example,
1.2,1.3,1,4,5,6
Remember to add a newline at the end.
2.2.2
item
The class is described according to the simple UML diagram below:
item <T>
-data:T
-------------------
+item(t:T)
+~item()
+next: item*
+getData():T
The class has the following variables:
• data: A template variable that stores some piece of information.
• next: A pointer of item type to the next item in the linked list.
The class has the following methods:
• item: This constructor receives an argument and instantiates the data variable with
it.
• ∼item: This is the destructor for the item class. It prints out ”Item Deleted” with
no quotation marks and a new line at the end.
• getData: This returns the data element stored in the item.
You will be allowed to use the following libraries: cstdlib,string,iostream.

Write a shell script of the following: “A Multiple Choice Question that contains 5 questions and each question carries 2 options. Choice will be given by the students. A record file is created each time the script runs to store the answers along with the total marks obtained. The record filename that has date and timing information as well as the student name.

I need this before the end of the day and in java please :)

10.12 Lab 9

In BlueJ, create a project called Lab9

A car dealership pays their salesmen a base salary every month. However, based on how many cars they sold (qtySold) they get a percentage of their salary as a bonus. To determine the percent bonus, the company uses the following chart.

Create a class called Employee as described in the following UML

NOTE: test methods as you implement them

• Constructor with no arguments – does nothing – open and close brace
• Set methods (mutators) set the field to the new values passed in to it
  • setLastName – sets field to the value passed in
  • setQtySold – checks the formal parameter – if it’s negative, it sets the field to zero otherwise it sets the field to the formal parameter
  • setBasePay – checks the formal parameter – if it’s negative, it sets the field to zero otherwise it sets the field to the formal parameter
• Constructor with arguments
  • Calls the set methods to set the fields
• Get methods (accessors) return the field that the get refers to
• computePercentBonus – determines the bonus based on the description above and returns the percent bonus (as an integer – 0, 5, 10, or 15)
• calculatePay – calculates the pay. It will have to call the computePercentBonus method to determine how much bonus to add to the base pay.

Create a text file using notepad. Save the text file in your Lab9 project folder and call it empData.txt. Copy the data below into the file. Save the file.

Tetzner 7 425.85
Martin 3 530.90
Smith 20 470.45
Jones 12 389.74
Glembocki 10 412.74 

Create a class called Main

• The main method should set up a scanner object so it will read the file you just created
• Remember to include the following imports

import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;

• Make sure you test the file when you open it – if it doesn’t find the file it should print an error message to the screen and exit the program
• Print the header to the screen using the following line of code. (you can just copy it) Take notice of the formatting. If you don’t understand what the numbers mean, ask.

System.out.printf("%-10s%8s%10s%8s%12s%n",  "Name","Qty Sold","Base Pay","%Bonus","Total Pay");

• Write a loop that reads in the name, quantity, and base salary from the file and puts the information into an object. It then uses the object to print the line of code (using the get methods) as seen on the output. (use formatting in the header above as an example of how to line up the columns)
• After you get the employees printing out, add the code to your loop to find the total amount paid and the top seller’s number of cars sold for the week and print them out as shown in the output below.

When you are done, upload the Employee class and the Main class to zybooks and submit it.

Sample Output

Name      Qty Sold  Base Pay  %Bonus   Total Pay
Tetzner          7    425.85       5      447.14
Martin           3    530.90       0      530.90
Smith           20    470.45      15      541.02
Jones           12    389.74      10      428.71
Glembocki       10    412.74       5      433.38
The company paid out a total of $2381.15 this week
Top seller this week sold 20 cars 

Phython:

Given a string x, write a program to check if its first character is the same as its last character. If yes, the code should output "True"

Ubuntu, Linux, MacOS use one of these systems.
1a. Create a C program that forks a child process that executes the command ‘ls’.
1b. Extend the program you created in Problem 1a such that it takes an argument. For example, the created child process should be able to execute the command ‘ls’ with any arbitrary single argument such as ‘ls -l’, and ‘ls -a’.
