Practice Test Week-1

1. Write an application that calculates and displays the weekly salary of an employee. 

In the main() method, prompt the user to enter the hourly_pay_rate, regular_working_hours, and overtime_hours. 

Create a separate method to calculate overtime pay, which is regular hours times the pay rate plus overtime hours times 1.5 times the pay rate; return the result to the main() method to be displayed.

2. When gasoline is Rs 120 per barrel, then the consumer’s price at the pump is between Rs 3.60 and  Rs 4.20 per gallon. 

Create a class named GasPrice such that its main() method holds an integer variable named price_per_barrel to which you will assign a value entered by a user at run time. 

Create a method to which you pass price_per_barrel. The method displays the range of possible prices per gallon. For example, if gas is Rs150 per barrel, then the price at the pump should be between Rs 4.50 and  Rs 5.25.

3. Create a class named TestBankAccount whose main() method declares 3 BankAccount objects. 

Call a getData() method 2 times. Within the method, prompt the user to enter values for each field for a BankAccount, and return a BankAccount object to the main() method where it is assigned to one of main()’s BankAccount objects. 

Do not prompt the user for values for the 3rd BankAccount object, but let it continue to hold the default values. Then, in main(), pass each BankAccount object in turn to a showValues() method that displays the data, calls the method that deducts the monthly fee, and displays the balance again. The showValues() method also calls the method that explains the deduction policy i.e. if the balance is less than Rs 1000 then Rs 100 will be deducted.  

4. Create a class named Billing that includes three overloaded computeBill() methods for a photo book store.

When computeBill() receives a single parameter, it represents the price of one photo book ordered. Add 7.5% tax, and return the total due. 

When computeBill() receives two parameters, they represent the price of a photo book and the quantity ordered. Multiply the two values, add 7.5% tax, and return the total due. 

When computeBill() receives three parameters, they represent the price of a photo book, the quantity ordered, and a coupon value. Multiply the quantity and price, reduce the result by the coupon value, and then add 7.5% tax and return the total due. Write a main() method that tests all three overloaded methods.

5. Create a class named State that holds the appropriate fields for name of the state, an population, and two City objects that hold data about the capital city and the most populour city. 

The State constructor requires parameters that represent the names and populations of the state, its capital, and its most populour city. Provide get methods for each field.

Create the City class to be a non-static, private inner class within the State class; the City class contains a city’s name and population. Create a class to assign values to and display values from two State objects.
