Step 1: Create a new Java project named ContainerPartyProject

---------

Step 2: Add a ContainerParty class to your project. It should contain:

            - The date of the party

            - A list of people attending

            - A list of containers at the party

            - The address of the party (this can be either a String or a Class)

---------

Step 3: Add a Container class in your project. It should be an abstract class. Your Container class must be properly encapsulated and include the following attributes:

• brand
• height
• color

In addition to a constructor that allows you to set all of these values, it should include a getInfo() method and an abstract calculateVolume() method.

---------

Step 4: Add a CircularContainer class to your project. Your CircularContainer must be a subclass of your Container class. In addition to the attributes that it inherits from Container, CircularContainer should add the following attributes:

• radius

It should include a getInfo() method and a calculateVolume() method that override the versions of these methods from your parent class. You may use the following formula for volume:

volume=π⋅radius²⋅height

---------

Step 5: Add a RectangularContainer class to your project. Your RectangularContainer must be a subclass of your Container class. In addition to the attributes that it inherits from Container, RectangularContainer should add the following attributes:

• width
• length

It should include a getInfo() method and a calculateVolume() method that override the versions of these methods from your parent class. You may use the following formula for volume:

volume=length⋅width⋅height

Important: In steps 3 and 4, your getInfo() methods must use the super keyword to leverage the getInfo() method of its superclass (Container).  Remember DRY - Don’t Repeat Yourself! You should not unnecessarily duplicate any code between getInfo() in your subclass and superclass!

---------

Step 6: Create a Person class with 3 attributes of your choice. Create attributes, methods, and constructors as necessary to complete the assignment.

        //code not shown
    }
}

Which of the following statements is true?

Questions 12-14 refer to the following:

public class A {
    public A () {
        System.out.print(“one ”);
    }

    public A (int z) {
        System.out.print(“two ”);
    }

    public void doStuff() {
        System.out.print(“six ”);
    }
}

public class B extends A {
    public B () {
        super ();
        System.out.print(“three ”);
    }

Which of the following is true about interfaces:

All methods in an interface must be abstract.

A class can only implement one interface.

An interface can have only non abstract methods.

Can not contain constants but can have variables.

None of the above.

What is the rule for a super reference in a constructor?

It must be in the parent class' constructor.

It must be the last line of the constructor in the child class.

It must be the first line of the constructor in the child class.

Only one child class can use it.

You cannot use super in a constructor.

Consider the following class definition.

public class WhatsIt {
    private int length;
    private int width;


    public int getArea () {
        // implementation not shown
    }

    private int getPerimeter () {
        // implementation not shown
    }
}

getArea()

getPerimeter()

width, length, getPerimeter()

width, length, getArea()

Questions 18 - 20 pertain to the following class, Point:

public class Point {
    private double x;
    private double y;

    public Point() {
        this (0, 0);
    }

    public Point(double a, double b) {
        /* missing code */
    }
    // ... other methods not shown
}

Which of the following correctly implements the equals method?

public boolean equals(Point p) {
    return (x == Point.x && y == Point.y);
}

public void equals(Point p) {
    System.out.println(x == p.x && y == p.y);
}

public boolean equals(Point p) {
    System.out.println(x == p.x && y == p.y);
}

public boolean equals(Point p) {
    return (x == p.x && y == p.y );
}

public void equals(Point p) {
    return (x == p.x && y == p.y );
}

The default constructor sets x and y to (0, 0) by calling the second constructor. What could be used to replace /* missing code */ so that this works as intended?

a = 0;
b = 0;

this(0, 0);

this (x, y);

a = x;
b = y;

x = a;
y = b;

Which of the following correctly implements a mutator method for Point?

public double getX() {
    return x;
}

public double getX() {
    return a;
}

public void setCoordinates (double a, double b) {
    x = a;
    y = b;
}

public void setCoordinates (double a, double b) {
    Point p = new Point(a,b);
}

None of the above

According to a Statistics Canada study from 2008: about 29% of women aged 18 to 24 engage in heavy drinking. (It is 47% for males.) The standard definition of heavy drinking is consuming 5 or more drinks on one occasion, 12 or more times over the past year. Assuming this to be true, if we choose a woman in this age group at random there is a probability of 0.29 of getting a heavy drinker. We can use software to simulate choosing random samples of women. (In most software, the key phrase to look for is “Binomial” This is the technical term for independent trials with “Yes/No” outcomes. Our outcomes here are “Heavy drinker” and “Not.”) a. Simulate 100 draws of 20 women and make a histogram of the percents who are heavy drinkers. Describe the shape, centre, and spread of this distribution. b. Simulate 100 draws of 500 women and make a histogram of the percents who are heavy drinkers. Describe the shape, centre, and spread of this distribution. c. In what ways are the distributions in parts (a) and (b) similar? In what ways do they differ? (Be sure to mention shape, location and spread.)

Assume Manchester University wants to make sure, its graduates would find jobs with the highest possible wage during the job search process, because this will help the university to increase its reputation, and as a result, it will be able to increase the tuition rates. How can the university increase the average wage level of their students get after they graduate, assuming it can no longer increase their skill level? I think question is clear there is no neeed extra explanation please feel free to answer question and you can mention about both productivity and equilibrium.

Prove Corollary 4.22: A set of real numbers E is closed and bounded if and only if every infinite subset of E has a point of accumulation that belongs to E.

Use Theorem 4.21: [Bolzano-Weierstrass Property] A set of real numbers is closed and bounded if and only if every sequence of points chosen from the set has a subsequence that converges to a point that belongs to E.

Must use Theorem 4.21 to prove Corollary 4.22 and there should be no mention of closed and bounded in the proof. The proof should start with,

[E closed and bounded] iff [E has the BW Property]

While in the grocery store look at the food labels of reduced fat/ fat-free foods and compare them to the original. Compare the Calorie count and sugar content of the reduced fat version to the original version. Report here what you find. Make sure to mention the product and what exactly you found. You just might be surprised. The easiest products to do this with are candy, chips, cakes, and cookies.

The following questions will help you know what to report on. (Was there much a difference in Calories, carbohydrate, protein, between the products? Were the serving sizes different?
