How do I create this instance variable?
1. gameLibrary of type ArrayList<GameInfo>
Step by step
Solved in 2 steps
- In C++ Define a class called textLines that will be used to store a list of lines of text (each line can be specified as a string). Use a dynamic array to store the list. In addition, you should have a private data member that specifies the length of the list. Create a constructor that takes a file name as parameter, and fills up the list with lines from the file. Make sure that you set the dynamic array to expand large enough to hold all the lines from the file. Also, create a constructor that takes an integer parameter that sets the size of an empty list. Write member functions to: remove and return the last line from the list add a new line onto the end of the list, if there is room for it, otherwise print a message and expand the array empty the entire list return the number of lines still on the list take two lists and return one combined list (with no duplicates) copy constructor to support deep copying remember the destructor!The WalkingBoard class represents a board with a figure standing on position x,y. Each position also has a value associated with it. Initialise the board in two different ways: either make it size×size or use the given dimensions and initial values. About the second way: The rows may not be uniform: they may have differing numbers of columns in them. Don’t simply take the argument array: create its copy in the field. All values are set to BASE_TILE_SCORE, or to the given value if that’s bigger. Operations. getPosition: returns the values of x and y in an array. getTile: returns the value of the of the board position. Let this condition be checked by the helper method isValidPosition. If it is an invalid position, throw an IllegalArgumentException. getTiles: returns the values of all the board positions. Don’t let the field contents be accessed from the caller: create and return an exact copy of the structure. getXStep and getYStep: helper methods, they indicate how far (-1,…Using C++ Without Using linked lists: Create a class AccessPoint with the following: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overLap that checks if two access points overlap their coverage and returns true if they do. Add a function signalStrength that returns the wireless signal strength as a percentage. The signal strength decreases as one moves away from the access point location. Represent this with bars like, IIIII. Each bar can represent 20% Test your class by writing a main function that…
- Create a class called integerset. A set is representedinitially as an array of ones and zeros. a[i] is 1 if integer number i is in the set, and 0 if the integer number i is not in the set. An object is instantiated by passing to the constructor an integer representing the range of the set.For a set of integers from 0 to 19 is instantiated as integerset a(20); the default constructor is used also. An array containing the appropriate number of elements is allocated dynamically and initialized by the constructor.Provide Public member functions for the common set operations (union –intersection), print a set as a list of numbers separated by spaces, Print ---for empty set, equalto member function that determine if two sets are equal in elements, and final lessthan member function that determine the set is less than other set in the elements.Include any additional operations that you think would be useful for a complex number class.Design, implement, and test your class.Java Task 1 Create an object of type FitnessExperiment that stores an array of StepsFitnessTracker, DistanceFitnessTracker, and HeartRateFitnessTracker objects. You could use code such as the following to initialise the array containing the fitness tracker measurements: FitnessTracker[] trackers = { new StepsFitnessTracker("steps", new Steps(230)), new StepsFitnessTracker("steps2", new Steps(150)), new StepsFitnessTracker("steps2", new Steps(150)), new HeartRateFitnessTracker("hr", new HeartRate(80)), new HeartRateFitnessTracker("hr", new HeartRate(80)) }; In the FitnessExperiment class, complete the implementation of the methods named getTotalSteps()and printExperimentDetails(). The comments in the code specify how they should operate and provide you with additional hints to get you started. You can use the method getSteps()in StepsFitnessTracker, but think how you will know the real type of each object in the array of fitness trackers (trackers in the example above). FitnessTracker…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…
- TaskDeclare and implement 5 classes: FloatArray, SortedArray,FrontArray, PositiveArray & NegativeArray.1- The FloatArray class stores a dynamic array of floats and itssize. 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 arrayelements 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 tothe 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…Create a class called CustomerListerwith a mainmethod that instantiates an array of Stringobjects called customerName. The array should have room for five Stringobjects. Use an initializer list to put the following names into the array:Cathy Ben Jorge Wanda FreddieUse newto create a second doublearray called customerBalancein the mainmethod. Allow room for five customer balances, each stored as a double.In the loop that prints each customer name, add some code to prompt the user to enter a balance for that customer. Read the keyboard input with a Scannerobject. Use the following balances for the input:100.00234.562.4932.32400.00After all the balances have been entered, print out each customer and his/her balance.Complete the Kennel class by implementing the following methods: addDog(Dog dog) findYoungestDog() method, which returns the Dog object with the lowest age in the kennel. Assume that no two dogs have the same age. Given classes: Class LabProgram contains the main method for testing the program. Class Kennel represents a kennel, which contains an array of Dog objects as a dog list. (Type your code in here.) Class Dog represents a dog, which has three fields: name, breed, and age. (Hint: getAge() returns a dog's age.) For testing purposes, different dog values will be used. Ex. For the following dogs: Rex Labrador 3.5 Fido Healer 2.0 Snoopy Beagle 3.2 Benji Spaniel 3.9 the output is: Youngest Dog: Fido (Healer) (Age: 2.0)

The Voter class was used to create instances of Voters which held their name and a voter identification number as instance variables, and the number of instances created as a static variable. This was the class diagram: The constructor takes a string, passed to the parameter n, which is the name of the voter and which should be assigned to the name instance variable. Every time a new voter is created, the static variable nVoters should be incremented. Also, every time a new voter is created, a new voterID should be constructed by concatenating the string “HI” with the value of nVoters and the length of the name. For example, if the second voter is named “Clark Kent”, then the voterID should be “HI210” because 2 is the value of nVoters and 10 is the number…
