Given this class, please add the requested methods in the designated spaces provided. Instance methods: a) Write two constructors that will initialize the instance variables for a Student instance as follows: 1) Write a constructor that takes in three parameters – an int, a String, and a double. The constructor will assign them to the ID, name, and GPA instance variables respectively. 2) Write a no-argument (zero-parameter) constructor that will set the ID to - 1, the name to “No name assigned”, and the GPA to –1.0. b) Write an accessor method for the name variable. c) Write a mutator method for the GPA variable. d) Write a toString() method that will display all three instance variables on a single line, with a | (vertical bar) character between each one. e) Write an equals() method that returns true only if all three instance variables are equal. public class Student { // declare instance variables here private int ID; private String name; private double GPA;

The Essay class has a default constructor, a constructor with two parameters, and a constructor with three parameters. Declare the following objects: essay1 with no arguments essay2 with essayTitle and essayAuthor as arguments essay3 with essayTitle, essayAuthor, and essayYear as arguments Ex: If the input is Painting Cole 1919, then the output is:   Essay: Undefined, Unspecified, 0 Essay: Painting, Cole, 0 Essay: Painting, Cole, 1919 Archive.java      public class Archive { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); StringessayTitle; StringessayAuthor; intessayYear;   essayTitle=scnr.next(); essayAuthor=scnr.next(); essayYear=scnr.nextInt();   /* Your code goes here */   essay1.print(); essay2.print(); essay3.print(); } } Essay.java public class Essay {   private String title;   private String author;   private int year;      public Essay() { // Default constructor      title = "Undefined";      author = "Unspecified";      year = 0;   }…

3- Create a class named Player with a default name as "player", a default level as 0, and a default class type of "fighter". Feel free to add any other attributes you wish! Create an instance method in the Player class called attack that takes another player as a parameter. This function should compare the level of the two players, and return whether the player won, lost, or tied. Finally create a loop that allows the user to input a name and a class type for two players; the level of both players should be determined at random (between 1 and 99). Print out the name and attributes of each player, and have the first player attack the second. Print whether the player won, lost, or tied. Ask if the user wants to try again. (Python code)

Design a Ship class that has the following members:• A field for the name of the ship (a string).• A field for the year that the ship was built (a string).• A constructor and appropriate accessors and mutators.• A toString method that displays the ship's name and the year it was built.Disign a CruiseShip class that extends the Ship class. The CruiseShip class should have thefollowing members:• A field for the maximum number of passengers (an int).• A constructor and appropriate accessors and mutators.• A toString method that overrides the toString method in the base class. The CruiseShipclass's toString method should display only the ship's name and the maximum number ofpassengers.Design a CargoShip class that extends the Ship class. The CargoShip class should have thefollowing members:• A field for the cargo capacity in tonnage (an int).• A constructor and appropriate accessors and mutators.• A toString method that overrides the toString method in the base class. The CargoShipclass's…

Create a class of Dog, some of the differences you might have listed out maybe breed, age, size, color, etc.    Then create characteristics (breed, age, size, color) can form a data member for your object.   Then list out the common behaviors of these dogs like sleep, sit, eat, etc. Design the class dogs with objects and methods.

The class contains one constructor: public Account (double initBal, String owner, long number) which initializes the instance variables.   1. Overload the constructor as follows: public Account (double initBal, String owner) - initializes the balance and owner as specified; randomly generates the account number. public Account (String owner) - initializes the owner as specified; sets the initial balance to 0 and randomly generates the account number. public Account () - initializes the owner with empty string name; sets the initial balance to 0 and randomly generates the account number.   2. Overload the withdraw method that also takes a fee parameter and deducts that fee from the account.   3. Write a driver program that invokes all four versions of the constructors and two versions of the withdraw methods. Think about how the compiler can tell which method is invoked.     Code:  //*******************************************************// Account.java//// A bank account class…
