- For this assignment you will be building on the Fraction class you began last week. All the requirements from that class are still in force. You'll be making five major changes to the class. Delete your set() function. Add two constructors, a default constructor (a constructor that takes no parameters) and a parameterized constructor (a constructor that takes parameters). The default constructor assigns the value 0 to the Fraction. In the parameterized constructor, the first parameter will represent the initial numerator of the Fraction, and the second parameter will represent the initial denominator of the Fraction. Since Fractions cannot have denominators of 0, the default constructor should assign 0 to the numerator and 1 to the denominator. Also, the parameterized constructor should check to make sure that the second parameter is not a 0 by using the statement "assert(denominatorParameter != 0);". To use the assert() function you'll also need to #include <cassert>. (Note, I…I've gotten stuck on this practice problem. I need help figuring this out. You need to make a Pet class that holds the following information as private data members: the name of the pet (e.g. "Spot", "Fluffy", or any word a user enters) the type of pet (e.g. dog, cat, snake, hamster, or any word a user enters) level of hungriness of the pet (2 means hungry, 1 means content, 0 means full) Your class also needs to have the following functions: a default constructor that sets the pet to be a dog named Buddy, with level of hungriness being “content” a parameterized constructor to allow having any type of pet the order of the parameters is: name of the pet, type of pet, hungriness level a PrintInfo function that prints the info for the pet according to the sample output below a TimePasses function that increases the hungry level of the pet by one (unless its hungry level is already 2, meaning hungry). a FeedPet function that changes the hungry level of the pet to 0 (Full) You must…Given the following class: public class Student { private long ID; private String name; } Write two constructor methods for the Student class, one without parameters and the other with.
- is this just for the candidate class or is the election class included?Please in pyth coding with correct indentation 4a) Given that you have a Liquid class that can be initialized with any amount of gallons, liters, ounces, etc, write the first line of the method that will allow you to add together two Liquid objects using operator overloading. Again, write ONLY the first line (method definition) – you do NOT have to write the entire method. 4b) Given that you have L1 and L2 which are instances of the Liquid class, write a line of code that uses operator overloading to add them together and assign the result to L3.Complete the code for the following program. You are provided with an abstract class called abst. Create a class that will be a child of abst and it will be called usesAbst. Your program will have an int variable called value, and all the appropriate methods, as well 2 constructors. The first constructor will simply set the variable value to 0. The second constructor will set the variable value to equal a passed in parameter. You do not have to comment your code. public abstract class abst{ public abst () { } //Outputs to the screen the message Hello public abstract void sayHello (); //returns the stored int value public abstract int getValue (); //sets the int value to x public abstract void setValue (int x); //Outputs to the screen the message Another method public void output () { System.out.println("Another method"); public String tostring () { return "This is an abstract class"; }
- 1) Through BlueJ, the class must define a method called isSpace that allows the book club staff to determine whether there is enough capacity for a group to attend. This method must take a single integer parameter representing the size of the group, and return a boolean result. The method must work as follows: If the value of the parameter is less-than or equal-to 0 then the method must return false. This case has priority over those following. If the value of the parameter is less-than or equal-to the space left in the book club (use the capacity and occupancy values in the to work this out) then the method must return true. Otherwise (i.e., if there is not space in the book club for the whole group) then the method must return false. 2) This method must not change the state of the BookClub object. In other words, both the current number of occupants and the capacity of the club must be exactly the same after it is called as it was before (Note that the return type of this method…All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Your task is to modify the Auto class below to override the equals method of the Vehicle class to test that the VIN and license plate number are identical.Which of the following statements is false? a. A class can contain only one constructor. b. An example of a behavior is the SetTime method in a Time class. c. An object created from a class is referred to as an instance of the class. d. An instance of a class is considered an object.

This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 milesWould you mind help me write racer class, sensor class, and timestamp class? (Note: The sensor class can have functions to determine if two sensors are adjacent and calculate the speed between them, while the time stamp class can have functions to calculate the time elapsed between two time stamps.) The class of racer should include : 1. Private data: racer number (int), an unknown number of sensor data. Sensor data includes sensor number (int that starts at 0 for start time; the last sensor is finish line), mile marker for the sensor double) and time stamp for each sensor (when racer passes the sensor) with hour, minute, second and millisecond. (You may want instance variables that holds racer's total race time, total race distance, total race speed.) 2. Default constructor 3. Copy constructor: make sure the code copies any vectors contained in the class 4. Set and get functions for private dat. 5. "get" function that computes and returns the racer's total time to complete…
