Implement the Critter class. Each critter C has attributes species, size, and age. • The constructor accepts arguments for the attributes above, in the order above. • You can expect size and age to be numeric values. Each critter C has a can_eat () method, which: Receives one argument, prey, which you can expect to be another Critter object. Compares prey 's size against C's. o If C is larger than prey, return True. Otherwise, return False. Each critter C also has a survive_year () method, which: • Increases C's size and age by 1, respectively, and returns C's current size.

Urgent Quick Question Write an equals method for the StepsFitnessTracker class that tests whether the one object is equal to another object that is passed as an argument (Object otherObject). The Object superclass provides an equals method that tests if two object references are equal. Your new equals method should override the Object equals method, and should test the following: • Return true if the current (this) object, and otherObject are identical references (hint: you can use the == operator for this). • Returns false if otherObject is null. • Returns false if the current (this) object and otherObject have different classes (hint: you can use the getClass() method provided by the Object superclass, see the Java 8 API documentation for details). • Casts otherObject to a StepsFitnessTracker, and tests for equality of each instance variable1 , if the instance variables are the same the method should return true. 1 To test for equality of each instance variable, you might want to...

Absolutely lost on this assignment. Any help would be greatly appreciated.

Create a code the follow way: Each student object should also contain thenumber of earned credits. Provide a constructor that sets this value based on parameter value. Overload theconstructor such that the number of earned credits is initially zero. Provide setter and getter for this newfield. Modify the toString method such that the new information is included in the description of thestudent. Modify the driver class main method to exercise the new Student methods.

Implement the Seller class as a derived class of Person class. Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages. Make sure to call the base class print to print thebase class data.• read() – overrides the base class read() to read the base class data and reads all additionalseller data...

Task 1:The first task is to make the maze. A class is created called Maze, in which a 2D array for the maze is declared. Your job is to implement the constructor according to the given javaDoc. When you completed this task, write a set of Junit test case to test your code.As you probably noticed, the maze is defined as a private variable. The second job for you is to write an accessor(getter) method that returns the maze. Other information about what is expected for this method is given in the starter code. public class PE1 { MazedogMaze; /** * This method sets up the maze using the given input argument * @param maze is a maze that is used to construct the dogMaze */ publicvoidsetup(String[][]maze){ /* insert your code here to create the dogMaze * using the input argument. */ }

Sally and Harry implement two different compareTo methods for a classthey are working on together. Sally’s compareTo method returns −1, 0, or +1,depending on the relationship between two objects. Harry’s compareTo methodreturns −6, 0, or +3. Which method is suitable?

Hello all! Need some help with this assignment. Need to create an array of 8 employees ( see image for details ) Thank you!

In this lab you will write three classes: Die, PairOfDice, and Player.The Die class mimics the rolling of a die. Specifically, this class will implement the following methods:• A default constructor initializing the number of sides of a die to 6.• An overloaded constructor that takes an integer number of sides (assume greater than 1).• roll which generates and returns a random number between 1 and the number of sides(inclusive).• An accessor method to read the value of the face on the die.• A toString method returning the string representation of the face value.The maximum number of sides should be stored as a private constant in the Die class. Also use theRandom class for the random number generator.The PairOfDice class mimics the rolling of two dice. Specifically, this class will implement thefollowing methods:• A default constructor that creates and initializes the number of sides of each die to 6.• An overloaded constructor that creates and takes two integer number of sides, one...

The goal of this coding exercise is to create two classes BookstoreBook and LibraryBook. Both classes have these attributes: author: Stringtiltle: Stringisbn : String- The BookstoreBook has an additional data member to store the price of the book, and whether the book is on sale or not. If a bookstore book is on sale, we need to add the reduction percentage (like 20% off...etc). For a LibraryBook, we add the call number (that tells you where the book is in the library) as a string. The call number is automatically generated by the following procedure:The call number is a string with the format xx.yyy.c, where xx is the floor number that is randomly assigned (our library has 99 floors), yyy are the first three letters of the author’s name (we assume that all names are at least three letters long), and c is the last character of the isbn.- In each of the classes, add the setters, the getters, at least three constructors (of your choosing) and override the toString method (see samplerun...
