Chapter 9, Problem 9.6PE
(Stopwatch) Design a class named StopWatch. The class contains:
- Private data fields startTime and endTime with getter methods.
- A no-arg constructor that initializes startTime with the current time.
- A method named start () that resets the startTime to the current time.
- A method named stop () that sets the endTime to the current time.
- A method named getElapsedTime () that returns the elapsed time for the stopwatch in milliseconds.
Draw the UML diagram for the class then implement the class. Write a test

(The Time class)
Design a class named Time.
The class contains:
- The data fields hour, minute, and second that represent a time.
- A no-arg constructor that creates a Time object for the current time. (The values of the data fields
will represent the current time.)
-A constructor that constructs a Time object with a specified elapsed time since midnight, January
1, 1970, in milliseconds. (The values of the data fields will represent this time.)
-A constructor that constructs a Time object with the specified hour, minute, and second.
- Three getter methods for the data fields hour, minute, and second, respectively.
-A method named setTime (long elapseTime) that sets a new time for the object using the
elapsed time. For example, if the elapsed time is 555550000 milliseconds, the hour is 10, the
minute is 19, and the second is 10.
Draw the UML diagram for the class and then implement the class.
Write a test program that creates two Time objects (using new Time (), new Time(555550000),…

Problem Description: A car dealership allows customer to purchase their new cars with different options. At this time, those options
are color, model, and air condition, as shown below in class CustomerOrder. Of course, the dealership wants the software to be
flexible enough to be able to add more options in the future, if needed.
CustomerOrder
-carColor: String
-carModel: String
-hasAirCondition: boolean
Q1) Write the full required code in Java to use the Builder design pattern to create class CustomerOrder.

1) bagUnion: The union of two bags is a new bag containing the combined contents of the original two bags. Design and specify a method union for the ArrayBag that returns as a new bag the union of the bag receiving the call to the method and the bag that is the method's parameter. The method signature (which should appear in the .h file and be implemented in the .cpp file is:
ArrayBag<T> bagUnion(const ArrayBag<T> &otherBag) const;
This method would be called in main() with:
ArrayBag<int> bag1u2 = bag1.bagUnion(bag2);
Note that the union of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the union of these bags contains x seven times. The union does not affect the contents of the original bags.
Here is the main file:
#include <cstdlib>#include <iostream>#include "ArrayBag.h"using namespace std;

- Indicate whether the statement is true or false. 13. The non-static methods of a class are called instance method. 14. A constructor has no type and is therefore a void method. 15. A class can have only two constructors. 16. In shallow copying, each reference variable refers to its own object. 21. The method finalize automatically executes when the class objects goes out of scope. 22. A mutator method of a class changes the values of data members of the class. 23. In java, the reference this is used to refer to only the methods, not the instance variables of a class. 24. Classes that are defined within other classes are called inside classes. 25. Modifiers are used to alter the behavior of the class 26. A constructor has the same name as the class. 27. Constructors are called like any other method. 28. You can perform some arithmetic operations on class objects.arrow_forward(Java) The Sculpture Subclass Write class as follows: The class is named Sculpture, and it inherits from the Painting class.

- Quick java class questionarrow_forward1) 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…arrow_forwardPython Programming Questions (OOP): Question 2: i) Write a complete class called GasPump to represent a gas pump. The class should have a constructor to set the amount of available gas supply (in litres) and the price of gas per litre. 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

Students' exam scores are included in the "Question1" tab in the attached worksheet. Empty data entries for the optional comprehensive final means that the student did not take the optional final.
