Car class Question

Design a class named car that has the following fields: YearModel: The yearModel field is an integer that holds the car's year model. Make: The make field references a string that holds the make of the car. Speed: The speed field is an integer that holds the car's current speed. In addition, the class should have the following constructor and other methods: Constructor: The constructor should accept the. car's year model and make as arguments. The values should be assigned to the object's yearModel and make fields. The constructor should also assign 0 to the speed field. Accessors: Design appropriate accessor methods to get the values stored in an object's yearModel, make, and speed fields. Accelerate: The accelerate method should add 5 to the speed field each time it is called. Brake: The brake method should subtract 5 from the speed field each time it is called. Next, design a program that creates a car object, and then cals the accelerate method fibe times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method 5 times. After each call to the brake method, get the current speed of the car and display it..........

Thanks for the help guys pseudocode and flowchart please

c++

1. write a c++ function that received two doubles that represent the sides of a triangle and an integer that represents the number of triangles of that size. calculate the area of all these triangles. remember area of a triangle is ahalf base times width. and return this value as a double.

Write a Java program to convert octal (integer) numbers into their decimal number equivalents (exactly the opposite of what you have done in Assignment 4). Make sure that you create a new Project and Java class file for this assignment. Your file should be named “Main.java”. You can read about octal-to-decimal number conversions on wikepedia

Assignment 4 is at the bottom

Objective

Your program should prompt the user to enter a number of no greater than 8 digits. If the user enters a number greater than 8 digits or a value less than 0, it should re-prompt the user to enter a number again*. You do not need to check if the digits are valid octal numbers (0-7), as this is guaranteed.

Instructions

• Note that the conversion logic should be in a separate method (not the main() method).
• main() method will take the input from the user and pass it to the conversion() method.
• The conversion() method will convert the input octal to decimal and print the output.
  • No return value is required.
  • a sample structure is shown below.

• Use a sentinel while loop to solve the problem.
• Ideally, you should copy your assignment 4 code here and modify it to serve the new purpose. This will save you time.

• USE ONLY INTEGER VARIABLES FOR INPUTS AND OUTPUTS.
• USE ONLY THE TECHNIQUES TAUGHT IN CLASS

main(){

int oct = user input;

conversion(oct);

}

void conversion(int o){

// logic goes here.

print(decimal);

}

Goals

• more experience in WHILE loop.
• experience in Java Methods
• logical thinking

Sample Runs

Sample Program Run (user input is underlined)

Enter up to an 8-digit octal number and I will convert it for you: 77777777

16777215

Sample Program Run (user input is underlined)

Enter up to an 8-digit octal number and I will convert it for you: 775002

260610

Sample Program Run (user input is underlined)

Enter up to an 8-digit octal number and I will convert it for you: 0

0

Sample Program Run (user input is underlined)

Enter up to an 8-digit octal number and I will convert it for you: 55

45

Sample Program Run (user input is underlined)

Enter up to an 8-digit octal number and I will convert it for you: 777777777

Enter up to an 8-digit octal number and I will convert it for you: 777777777

Enter up to an 8-digit octal number and I will convert it for you: 700000000

Enter up to an 8-digit octal number and I will convert it for you: 77

63

Assignment 4:

// Main.java : Java program to convert decimal number to octal

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

int inputNum, convertedNum;

Scanner scan = new Scanner(System.in);

// Input of integer number in decimal

System.out.print("Please enter a number between 0 and 2097151 to convert: ");

inputNum = scan.nextInt();

// validate the number

if(inputNum < 0 || inputNum > 2097151)

System.out.println("UNABLE TO CONVERT");

else

{

int weight=0; // weight of the digit, used for converting to octal

convertedNum = 0; // variable to store the number in octal

int temp = inputNum;

int digit;

// loop that continues till we convert the entire number to octal

while(temp > 0)

{

digit = (temp%8); // get the remainder when the number is divided by 8

// multiply the digit with its weight and add it to convertedNum

convertedNum += digit*Math.pow(10, weight);

temp = temp/8; // remove the last digit from the number

weight++; // increment the weight

}

// display the integer in octal

System.out.printf("Your integer number " + inputNum + " is %07d in octal",convertedNum);

}

scan.close();

}

• Write a function power(x,i) that takes an int i and a float (i.e. real number) x and returns xi, do not use Python’s in-built power function x**i , instead write a loop to do so using only multiplication.
• Now do use the power function x**i to write a second function unit_test(y) that tests whether your first function is working correctly or not.  
• Does power(x,i) work for any value of x and i ? For which values x and i does it throw an error? What happens if the input variables are letters instead of a float and an int?
• Write a new function power_2(x,i)so that instead of throwing an error, the function prints a message that explains what went wrong in each case?

Need hep with this c++ program

Declare an array of integers of size 8 and initialize it with any non-duplicate integer values you like. Don’t enter the values in any order. Print the unsorted array. Sort the array using selection sort or insertion sort in descending order. Print what sort you are using. Write any additional functions that you need for sorting. Keep monitoring the number of comparisons and number of swaps performed while sorting. Report both after sorting. Print the sorted array.

Design and implement a class called Boxthat represents a 3-dimensional box.1.Instance DataYour Box class will need variables to store the size of the box. All of these variables will be of type ‘private double’.•width•height•depthYour Boxclass will also need a variable to keep track of whether or not the box is full. This will be of type ‘private boolean’.•full2.ConstructorDeclaration: public Box( double width, double height, double depth)•Your Boxconstructor will accept the width, height,and depthof the box.•In your constructor, initialize the width, height,and depthinstance variables to values passed in as parameters to the constructor.•Each newly created box will be empty. This means that you will also need to initialize fullto false in your constructor.3.Getter and Setter MethodsInclude getter and setter methods for all instance data. We will assume that all supplied dimension values are positive values. Here is an example of the method declarations for width to get you started.•Getter: public double getWidth()•Setter: public void setWidth(double width)4.Public Methods•Write a public double volume()method that will calculate and return the volume of the box based on the instance data values.•Write a public double surfaceArea()method that will calculate and return the surface area of the box based on the instance data values.5.toString MethodWrite apublic String toString() method that returns a one-line description of the box. The description should provide its dimensions and whether or not the box is full. Format all double values to 2 decimal places.Example: An empty 4.00x 5.00 x 2.00 box.Part 2: Testing your ClassNow, create a driver class called BoxTestand do the following in the main method.Create your first box1.Create a Boxvariable called smallBoxand instantiate it with width 4, height 5, and depth 2.2.Print the one-line description of smallBoxusing its toString()method.3.Confirm that smallBox’s width, height, and depth getter methods are returning the correct values.4.Confirm that smallBox’s volume()and surfaceArea()methods are returning the correct values.5.Use smallBox’s setter methods to change it from “empty” to “full” and to change its dimension values to width 2, height 3, and depth 1.6.Print the one-line description of smallBoxusing toString()again, and confirm that all changed values are reflected.7.Confirm that all getter and other methods return the correct values reflecting smallBox’s current dimensions and full value.Create several boxes and find the largest oneDo not delete what you did above! Add the following code to the end of your BoxTestclass.1.Declare and instantiate an ArrayListobject that will store your Boxobjects.See the listing below as a sample of how to use the ArrayListbut with Stringobjects.2.In a standard “for” loop that iterates 5 times, create a new Boxwith randomly generated width, height, and depth and add the box to your ArrayList. Limit dimension values to a reasonable range. Randomly generate a Boolean value and use it to call the Box’s method for setting “full” (use the nextBoolean()method in the Randomclass).3.In the loop, print outthe Box’s details, labeled according to the loop iteration (i.e. if this isthe first iteration of the loop, label the box as “Box 1: “ in the output).4.Use a for-each loop(as shown in the listing above)to find the Boxwith the largest volume. You will need to declare a largest box variable of type Boxto keep track of the largest box. This variable needs to be declared outside of the loop so that it will still be available when the loop ends. Use conditional statements inside the loop to compare the current Box to the largest Box, so far, and update the largest box variable when appropriate.5.After the loop, print the details of the largest Box. Confirm that you program identified the correct boxes.

Question 3: Write the following Java program.

A. Create a class called Quadrilateral that contains the following: [4 Marks]

• Five double type data fields for: side1, side2, side3, side4, and perimeter

• A no-argument constructor that creates a Quadrilateral with all sides equal to 1

• Methods named setSide1(double s1), setSide2(double s2), setSide3(double s3), and

setSide4(double s4) to set the values of the four sides

• A method named calculatePerimeter( ) to calculate and return the perimeter of the

quadrilateral

B. Create a child class called Square that contains a method named calculateArea() to

calculate the area of the Square. [2 Marks]

C. Create a java main class named TestQuad to do the following: [4 Marks]

• Create a Quadrilateral object named Quad1 and a Square object named Sq1.

• Call the methods setSide1(double s1), setSide2(double s2), setSide3(double s3), and

setSide4(double s4) to:

o set the sides of Quad1 to 10, 20, 25, and 30, respectively

o set all sides of Sq1 to 3

• Display the perimeter of Quad1 by calling the method calculatePerimeter ( ). Display

the perimeter of Sq1 by calling the method calculatePerimeter ( ).

• Display the area of Sq1 by calling the method calculateArea()

Hint: Perimeter = sum of all sides & Area of Square = side * side

JAVA - Write a program that prompts the user (at the command line) for 4 positive integers, then draws a pie chart in a window. Convert the numbers to percentages of the numbers’ total sum; color each segment differently; use Arc2D. No text fields (other than the window title) are required. Provide a driver in a separate source file to test your class.

Please use the following:

java.lang.Object

java.awt.Graphics

java.awt.Graphics2D

Take note of the following:

setPaint

setStroke

fill

// imports

public class PieChartPanel extends JPanel {

// attributes

// constructor

public void paintComponent(Graphics g) {

super.paintComponent (g);

Graphics2D g2d = ( Graphics2D ) g;

...

}

There should be a paintComponent method that calls its parent
