1) Create a "Car" class that keeps car ids and prices. And create a "Galleries" class that holds the car list for a particular gallery. In this class there should be methods for get / set and print for car name, car number and car list. Adding / Removing Cars to the List in This Class should have methods. And create another method to find and print the IDs of Cars with Car Segment equal to X. (print (X)). Car Prices are as follows according to the segments. 0-19999 -> Z20000-29999 -> Y30000-44999 -> T45000-100000 -> P Apply the Car list using "Single Linked List"(Node, newNode, head). The program should be written in JAVA.
Write a class encapsulating the concept of converting integer grades to letter grades (A, B, C, D, or F), assuming grades are composed of a list of integers between 0 and 100 (instance variable). Write the following methods: • A constructor with just one parameter, the number of students; all grades can be randomly generated. • Accessor, mutator, toString, and equals methods. • A method returning an array of chars corresponding to the integer grades (90 or above should be converted to A, 80 or above to B, 70 or above to C, 60 or above to D, and 59 or less to F). • A method returning the number of A’s. • A method returning an array of int counting how many A’s, B’s, C’s, D’s, and F’s were received.
Implement a class Season that represents a season during a specified year. For purposes of thisproblem, assume that the seasons in each year are, in order, 'Winter', 'Spring', 'Summer', 'Autumn' .__init__, __repr__A Season object is created by calling the constructor and supplying two optional arguments:1. season, defaults to 'Winter'2. calendar year, an int , defaults to 2023For the __repr__ , see the usage below: The next and prev methods modify a Season object by changing it to the next season or previousseason in sequence, respectively. Note that the seasons can "roll over" or "roll back" and that this maychange the year by +/-1. 1. During each year, the seasons occur in this sequence: 'Winter', 'Spring', 'Summer', 'Autumn' 2. next - change to next season, if the current season is Autumn then year will increase by 1 3. prev - change to previous season, if Winter then year will decrease by 1 Implement the == operator ( __eq__ method) to compare two Season…
Write a class that represents a player in a game. The player should have a name, password,experience points, an inventory array of four strings, and a location x,y. Your class shouldhave mutator and accessor methods for all variables. For example: setName(), getName(). Itshould have a suitable display method. Mutators and accessors should be public but allvariables should be private. To implement get inventory, use string * getInv(); Use the scoperesolution operator to implement larger methods such as display(). Use in class methods forshorter methods such as setName(), getName(). (in C++)Example:void setName(string name){this->name = name;}string *getInv();...string* player::getInv(){return inventory;}Note that in the above method setName “this->” is required for disambiguation. If writtenvoid setName(string n){name = n;}“this->” is not required.Write a test program that creates three players and displays them.Example Output:This program generates three player objects and…
Write a class called Book having the following data members: title (String), author1 (String), author2(String), publisher (String), yearPublication (int), isbn (String), accessionNum (long), issuedTo (LibMember). Include following public methods in the class: Default constructor (without any parameters), constructor with 6 parameters (except for issuedTo – initialize issuedTo to null), set and get methods for all attributes, equals and toString. NOTE: The ISBN is a unique 13 digit number assigned by the publisher. It is like barcode. As there can be multiple copies of a book in a library, the libraries assign a unique number, called accession number, to every book in the library to keep track of the books in the library. Assume that accession number starts from 1001.
Write a compareTo method that compares two Song objects based on the artist, and title within artist. For example, given the following Songobjects: "Glass Animals""Heat Waves" "Elton John, Dua Lipa""Cold Heart" "Adele""Easy on Me" "Doja Cat""Kiss Me More" "Adele""My Little Love" They will be put in the following order: "Adele""Easy on Me" "Adele""My Little Love" "Doja Cat""Kiss Me More" "Elton John, Dua Lipa""Cold Heart" "Glass Animals""Heat Waves" In which class does the compareTo method belong?
Please in pyth coding with correct indentation 4a) Given that you have a Liquid class that can be initialized with any amount of gallons, liters, ounces, etc, write the first line of the method that will allow you to add together two Liquid objects using operator overloading. Again, write ONLY the first line (method definition) – you do NOT have to write the entire method. 4b) Given that you have L1 and L2 which are instances of the Liquid class, write a line of code that uses operator overloading to add them together and assign the result to L3.
