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

public static void main(String[] args) {

int inputNum, convertedNum;

// validate the number

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);

The automobile fuel called E85 consists of 85 % ethanol and 15 % gasoline. E85 can be used in so-called "flex-fuel" vehicles (FFVs), which can use gasoline, ethanol, or a mix as fuels. Assume that gasoline consists of a mixture of octanes (different isomers of C8H18), that the average heat of combustion of C8H18(l) is 5400 kJ/mol, and that gasoline has an average density of 0.70 g/mL. The density of ethanol is 0.79 g/mL.

For Part A, start with the given L of gasoline and use the density of the gasoline as well as the molar mass of  C8H18 to determine the moles of gasoline. Once you have found the moles of gasoline you will use the provided heat of combustion to determine the energy produced. You do not need to use Appendix C because you are using the provided heat of combustion.

For Part B, do the same with the ethanol. You will use the heat of combustion for ethanol from the extra credit homework problem 5.79. If you did not do the that homework problem, you will need to write the balanced equation for the combustion of ethanol paying attention to the phases. Use the phase of gas for the water. Then calculate the heat of the combustion reaction from the heats of formation in Table C.

For Part C, you will need to use a weighted average. This is the same formula we used to determine the average atomic mass.

For Part D, you are starting with the given gallons of gasoline and will need to use the heat of combustion produced for the given liters of gasoline as a conversion factor to determine the energy produced from the given gallons. The heat of combustion produced from the liters of gasoline is from Part A. Now take the energy produced from the gallons of gas and use that as the given. Using the heat of combustion produced for the liters of E85 from Part C, determine the gallons of E85 necessary to produce that much energy.

For Part E, you will use the gallons of gasoline

A)By using the information given as well as data in Appendix C, calculate the energy produced by combustion of 2.0 L of gasoline

B)By using the information given as well as data in Appendix C, compare the energy produced by combustion of 2.0 L of ethanol. Consider that water is in the gaseous state.

c)Assume that the density and heat of combustion of E85 can be obtained by using 85 % of the values for ethanol and 15 % of the values for gasoline. How much energy could be released by the combustion of 2.0 L of E85?

E)If gasoline costs $ 3.10 per gallon in the United States, what is the break-even price per gallon of E85 if the same amount of energy is to be delivered?
