(Conversions between Celsius and Fahrenheit) Write a class that contains the following two methods:
/** Convert from Celsius to Fahrenheit */
public static double celsiusToFahrenheit (double celsius)
/** Convert from Fahrenheit to Celsius */
public static double fahrenheitToCelsius(double fahrenheit)
The formula for the conversion is as follows:
fahrenheit = (9.0 / 5) * celsius + 32

Write a class that contains the following two methods:
/** Convert from Celsius to Fahrenheit */
public static double celsiusToFahrenheit(double celsius)
/** Convert from Fahrenheit to Celsius */
public static double fahrenheitToCelsius(double fahrenheit)
The formula for the conversion is as follows:
fahrenheit = (9.0 / 5) * celsius + 32
celsius = (5.0 / 9) * (fahrenheit – 32)
Write a test program that invokes these methods to display the following table:
NOTE: Celsius starts at 40 and should be converted to Fahrenheit, on the same line Fahrenheit starts at 120 and should be converted to Celsius

- Exercise: 1) Design a class ComboLock that works like the combination lock in a gym locker, as shown below. The lock is constructed with a combination-three numbers between 0 and 39. The reset method resets the dial so that it points to 0. The turnLeft and turnRight methods turn the dial by a given number of ticks to the left or right. The getStatus method returns a Boolean indicating whether the lock is opened(true) or closed(false). The lock opens if the user first turned it right to the first number in the combination, then left to the second, and then right to the third. 02 36 2) Document your class. 3) Provide a tester class and test a scenario in which you create a comboLock having the code (25, 36, 19), unlock it successfully, and print the status of the lock after each turn. 4) Put the ComboLock class and the tester class in two distinct packagesarrow_forward(After reading the instructions given in the pictures attached, read the following) Class membersdoctorType Class must contain at least these functionsdoctorType(string first, string last, string spl); //First Name, Last Name, Specialty void print() const; //Formatted Display First Name, Last Name, Specialtyvoid setSpeciality(string); //Set the doctor’s Specialtystring getSpeciality(); //Return the doctor’s SpecialtypatientType Class must contain at least these functionsvoid setInfo(string id, string fName, string lName,int bDay, int bMth, int bYear,string docFrName, string docLaName, string docSpl,int admDay, int admMth, int admYear,int disChDay, int disChMth, int disChYear);void setID(string);string getID();void setBirthDate(int dy, int mo, int yr);int getBirthDay();int getBirthMonth();int getBirthYear();void setDoctorName(string fName, string lName);void setDoctorSpl(string);string getDoctorFName();string getDoctorLName();string getDoctorSpl();void…arrow_forwardUsing JAVA Part A) Design a class Message that models an e-mail message.

The class should include: -An accessor and a mutator to set and get the gas price. -An accessor to get the current amount of gas supply. -A method to add fuel to the gas supply. Note that the maximum capacity of the pump is 5000 litres. If we try to add too much fuel, once the maximum capacity is reached, no more fuel can be added. -A method that sells a specific amount of gas. This method should reduce the supply of available gas by the amount sold and return the total cost of the gas sold. If the supply of the available gas is less than the amount requested, then only the existing supply should be sold. ii) Using the class defined in part (i), add a driver that will: - Create an object called ‘shell’ of the class GasPump and initializes it…arrow_forward
