Students have asked these similar questions
Create a class Animal and Add a protected data member named id of integer type.
Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0.
Also provide parameterized constructor and toString method.
Add an abstract method tellAboutSelf method to Animal class with public access
Add another abstract method speak method to Animal class.
Reptile, Bird, Mammal
Next create the three child classes which extends form Animal class.
Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”.
Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the specified id passed to the constructor also it…

This is the question -
Create a class named Rock that acts as a superclass for rock samples collected and catalogued by a natural history museum. The Rock class contains the following fields:
sampleNumber - of type int
description - A description of the type of rock (of type String)
weight - The weight of the rock in grams (of type double)
Include a constructor that accepts parameters for the sample number and weight. The Rock constructor sets the description value to "Unclassified". Include get methods for each field.
Create three child classes named IgneousRock, SedimentaryRock, and MetamorphicRock. The constructors for these classes require parameters for the sample number and weight. Search the Internet for a brief description of each rock type and assign it to the description field using a method named setDescription inside of the constructor.
I am only missing two checks and they seem to be with the rock, here is my code then I will copy one check -

Class MyPoint: Class MyPoint is used by class MyShape to define the reference point, p(x, y), of the Java display coordinate system, as well as by all subclasses in the class hierarchy to define the points stipulated in the subclass definition. The class utilizes a color of enum reference type MyColor, and includes appropriate class constructors and methods. The class also includes draw and toString methods, as well as methods that perform point related operations, including but not limited to, shift of point position, distance to the origin and to another point, angle [in degrees] with the x-axis of the line extending from this point to another point.

The ConwayCell implements the standard behavior of a call in Conway’s Game of Life. You only need to implement and test two new classes. You will create two different cells, derived from AbstractCell. 1. Alternating Cell The first class that you should create is a class named AlternatingCell. This is a cell that should alternate between being alive and dead with each generation. Add one or more of your AlternatingCells to your ConwayWorld. You can see how to add a cell in line 15 - 20 of Main.java. Give your AlternatingCell a unique display character when it is alive so that you can see it in your conway world. 2. Your own cell For the second cell you should feel free to implement any behavior that you want. If you are having trouble thinking of ideas then post up a question.

- 1 - Student class Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7).

There should also be a getArea method that returns the area (derived from the radius) A doesOverlap method. This method should accept a Circle as an argument, and return true if this circle overlaps the circle that the method was invoked on.
