Class name: TestScores Fields: - name : String - totalScore : double - numScores : int Methods: + TestScores(name : String) + addTestScore(earned : double) : void + getNumTestsTaken() : int + getAverage() : double Write in java and use test case 1 as an referencepublic class BackAccount{public double Balance { set; get; }public void Deposit(double amount){Balance = Balance + amount;} }Transaction FeesTransaction TypeDeposit Withdrawal Check BalanceAmount0.25 % of the deposit amount 0.5 % of the withdrawal amount FreeUsing the code snippet above, complete the bank account functionality by adding Withdraw and CheckBalance methods. In your definition for the Withdraw method, check if the account has sufficient funds before making a withdrawal. Apply transaction fees as per the table above:3. Write a class Student having attributes to store the following data: Name, fathers’ Name, department, degree, enrolment, seat number, marks of three subjects. Also write a class to test all methods of Student class. Add the following methods in the above class. • int getTotal() : This methods returns the total of marks • void printTotal() Prints the total marks of Student • float getPercentage() this method calculates the percentage of a student • void printPercentatge() this method prints the percentage of student • char getGrade() this method calculates and returns the grade. • void printGrade() this method prints the grade of a student. • void printInfo() This method prints all information of the student.
- private float c; private void method2(double y) { c = y; } in another class we created an object of the first class then within in it : tester.method2 (10.0f); are there any errors ? how many errors if there are any and with explanation please.private int b; public int method3() { return b; } // in another class an object of the first class was introduced and inside the second class : float y = tester.method3(); are there any errors ? and explain pleaseCreate a class with name savingaccont.In this class you have to write the static method having name CalculteFutureValue which takes three parameters of type double along with return type double.This function should implement the formula given below.The formula, which is known as the future value formula, is:F = P * (1 + i)tThe terms in the formula are as follows: F is the future value of the account after the specified time period. P is the present value of the account. i is the monthly interest rate . t is the number of months . Write Driver class which contains main function that prompts the user to enter the account’s present value, monthly interest rate, and the number of months that the money will be left in the account. The program should pass these values to a function named CalculteFutureValue that returns the future value of the account, after the specified number of months. The program should display the account’s future value.
- 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 Do not forget to Introduce your Program to the user with descriptive information. Do not forget to include a block Comment header at the start of your Source Code.Write a class that contains thefollowingtwo methods:/** Convert from pounds to kilograms */public static double poundToKilogram(double pound)/** Convert from kilograms to pounds */public static double kilogramToPound(double kilogram)The formula for the conversion is:pound = 0.453 * kilogramkilogram = 2.204 * poundWrite a test program that invokes these methods to display the following tables:1) Through BlueJ, write if the current number of shoppers is greater than or equal to the number leaving then the number of shoppers is decreased by the number leaving. Otherwise, the following error message must be printed and the number of shoppers present must be set to 0. There is an error in the number of shoppers. Use System.out.println to print the message. 2) The class must define a method called leaving that takes a single integer parameter. This represents the number of shoppers leaving the club at a particular point. You may assume that the parameter's value will always be greater than zero and you do not have to check for that. If the current number of clubbers is greater than or equal to the number leaving then the number of clubbers is decreased by the number leaving. Otherwise, the following error message must be printed and the number of clubbers present must be set to 0. There is an error in the number of shoppers. Use System.out.println to print the error message. 3)…
- The Huntington Boys and Girls Club is conducting a fundraiser by selling chili dinners to go. The price is $7 for an adult meal and $4 for a child’s meal. Write a class that accepts the number of each type of meal ordered and display the total money collected for adult meals, children’s meals, and all meals. Save the class as ChiliToGo.java.Create a class IndependenceUSA and write code which asks the user to enter text that contains the American Independence day ( July 4th 1776). Read the date using the method next() 3 times. The user should enter the Independence day in the order month, day, year as shown in the first two runs below( we are not case sensitive) . Use the String method compareToIgnoreCase() to test the validi-ty of the date and print “Hurrah!” if the date entered is correct, or “No, no , no! Incorrect!” if the date incorrect is incorrect, or of the date entered in the wrong order. In other words, you compare your input to “July” , “4”, “1776” , in that order and you don't case for capital or small case letters.1: Based on Program 13-1 in the textbook, create a class name “Circle” with the following declarations by completing missing methods. (Hint: you can use PI=3.14.) //Circle class declaration class Circle { private: double radius; public: void setRadius(double); double getRadius() const; double getArea() const; double getPerimeter() const; };
