Chapter 6, Problem 7PP
Write a Temperature class that represents temperatures in degrees in both Celsius and Fahrenheit. Use a floating-point number for the temperature and a character for the scale: either ‘C’ for Celsius or ‘F’ for Fahrenheit. The class should have
- Four constructors one for the number of decrees, one for the scale, one for both the decrees and the scale, and a default constructor. For each of these constructors, assume zero degrees if no value is specified and Celsius if no scale is given.
- Two accessory methods one to return the temperature in degrees Celsius, the other to return it in degrees Fahrenheit. Use me formulas from Practice Program 5 of Chapter 3 and round to the nearest tenth of a degree.
- Three set methods: one to set the number of degrees, one to set the scale, and one to set both.
- Three comparison methods: one to test whether two temperatures are equal, one to test whether one temperature is greater than another, and one to test whether one temperature is a less man another.
Write a driver program that tests all the methods. Be sure to invoke each of the constructors, to include at least one true and one false case for each comparison method, and to test at least the following three temperature pairs for equality; 0.0 degrees C and 32.0 degrees F, –40.0 degrees C and –40.0 degrees F, and 100.0 degrees C and 212 0 degrees F.

You are required to build a class to represent the a cup of coffee. Call your class CoffeeCup. A coffee cup will have following characteristics 1. type (sting) // can be mocha, cupaccino, etc 2. temperature (float): represents the measure of temperature in degrees 3. volume (float):// the volume of coffee in the cup in ml liters 4. sugar (int):// no of teaspoons of sugar added to the coffee Provide these methods 1. parameterized constructor CoffeeCup(string t, float temp float vol, int sug) 2. Provide setters for temperature, and sugar and volume. 3. Provide getters of temperature, sugar, volume and type. 4. void heatUp(): //this method represents the process of heating the coffee, the current temperature of coffee goes up by one degree if it is below 100 and stays the same otherwise 5. void cooldown(): the process of cooling down. The temperature goes down by one degree but will not go below 0 6. bool isSweet():// returns true if this coffee has any amount of sugar in it and 0 if not…
For the 'The Chicken class' on the app intelliJ in java. The Chicken class must:• Define three fields called exactly name, pricePerKilo and inStock. The name field must be of type String, the pricePerKilo must be of type int (representing the cost per kilo in pence) and the inStock field must be of type boolean.• Initialise the three fields via a constructor that takes exactly two parameters. The first parameter must be of type String and the second parameter must be of type int. The first parameter must initialise the name field and the second must initialise the pricePerKilo field. The constructor must set the inStock field to true for all Chicken objects. There must be no parameter to the constructor for the inStock field.• Define getters for all three fields using the standard getter naming convention. In particular, note that the getter for the inStock field must be called getInStock rather than isInStock.• Define setters for the pricePerKilo and inStock fields using the standard…

You have to make object of that and print the result In javaarrow_forwardCreate a class named Pay that includes five double variables that hold hours worked, rate of pay per hour, withholding rate, gross pay, and net pay. Create three overloaded computeNetPay() methods. When computeNetPay() receives values for hours, pay rate, and withholding rate, it computes the gross pay and reduces it by the appropriate withholding amount to produce the net pay. (Gross pay is computed as hours worked multiplied by pay per hour.) When computeNetPay() receives two parameters, they represent the hours and pay rate, and the withholding rate is assumed to be 15%. When computeNetPay() receives one parameter, it represents the number of hours worked, the withholding rate is assumed to be 15%, and the hourly rate is assumed to be 5.85. Write a main() method that tests all three overloaded methods. Save the application as Pay.java.arrow_forwardWrite a class that prompts the user for the day’s high and low temperatures.

- Write a class to represent a thermometer. The class must provide aparameterless constructor that initializes the temperature of the thermometer to37o Celsius (the average human body temperature). Store the temperature as afield in the celsius scale.Your class should provide methods to get and set the temperature using degreesCelsius, Fahrenheit, or Kelvin. For example, assume that the Celsius methodmay be used to set the temperature to 100oC. If the method to get thetemperature in Fahrenheit is called, it should return 212 (the equivalent of100oC). If the Fahrenheit method is used to set the temperature to 32oF, then themethod to retrieve the temperature in degrees Kelvin should return 273.15.To be clear, your thermometer keeps track of one temperature value (that youmay store using any scale that you like). It provides methods to set and retrievethe value using any of the three scales.Make sure to include a toString method that prints the current temperature inall 3 scales.
