Chapter 24.3, Problem 24.3.6CP
Program Plan Intro
Memory leak:
When an object is no longer used by the application but the garbage collector cannot remove them from working memory. This is because the object is still being referenced which results in consumption of more memory.

An initializer list can be used to instantiate an array object instead of using the new operator.
1- The FloatArray class stores a dynamic array of floats and its size. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the array elements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add to the array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the front of the array.4- The PositiveArray that inherits from SortedArray. It has:- A parameterized constructor…

- create a driver program, CarTestDriver that uses a Garage object to store Cars. The Garage object is an instantiation of a Garage class that contains “parking”, an array of Car types. You must use a Car[] not an ArrayList<Car> for the “parking” in the garage. I suggest setting up the Car class with a default constructor that generates random values to create each new Car object. The rules for driving the cars from the garage are: The size of the garage is specified by the user. The user may only use cars from the garage A Car is removed from the Garage when a user retrieves a Car from the Garage. The Car is returned to the Garage, after it is driven if it does not run out of fuel. The user interacts with the Car object after the Car object is retrieved from the garage. The program should not fail due to a user selection. A car may only be refueled when the user selects the Car for use, prior to being removed from the Garage The user may select to drive any car that is currently…arrow_forwardExercise 1• Create a class that sorts a list in ascending order. Make use of the Collections method sort• The list should be a list of Strings.• Test your code with {“Hearts”, “Diamonds”, “Clubs”, “Spades”}• Before and after the sort, use the implicit call to the list’s toString method to output the list contents. Exercise 2• Create a class with the same requirement as in Exercise 1, but the sort should be in descending order• Make use of the Comparator interface• Make use of the static collection method reverseOrder javaarrow_forward6. the grade is under 20 which is outlier, remove it from the array list. 7.

The statement newList.mergeLists(list1, list2); creates a new linked list with the elements in the order 2 3 5 6 7 8, and the object newList points to this list. Also, after the preceding statement executes, list1 and list2 are empty. 2. Write the definition of the function template mergeLists to implement the operation mergeLists.arrow_forward12.
