OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Q4. The classes DateInfo and Student in different packages
- Create two packages, calendar, and personal_data
- Create a class called DateInfo inside the package calendar
- The class DateInfo has only three variables, day (type integer), month (integer), year (integer).
- The three variables day, month and year, are invisible outside the class DateInfo.
- Define a constructor for the class DateInfo with three-arguments to initialize the variables day, month and year.
- Write a method called getDateFormat, that returns a date format example; 19/4/2016 (the method returns a String type for simplification)
- Create a class called Person inside the package personal_data.
- The Person class has only two variables, name (type String) and birthDate (type DateInfo).
- Create two Person objects for Omar and Rami, Omar's birthDate is 28/8/1998 and Rami's birthDate is 13/9/1996

Note- for code use C++ only .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 - import java.util.*;…

The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise. Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Ex: If the input is: Pablo Picasso 1881 1973 Three Musicians 1921 the output is: Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921 If the input is: Brice Marden 1938 -1 Distant Muses 2000 the output is: Artist: Brice Marden, born 1938 Title: Distant Muses, 2000 I have the code but I am getting errors that I can't seem to get rid of any suggestions would be appreciated2019 AP® COMPUTER SCIENCE A FREE-RESPONSE QUESTIONS 2. This question involves the implementation of a fitness tracking system that is represented by the StepTracker class.

- Create a class MyTime which has the datamembers as follows: 1. hour: integer (1 to 12)2. minute: integer (0 to 59)3. second: integer (0 to 59)4. pm: bool variable. True means PM time and false means AM time. Implement a default constructor, a parameterized constructor and a copy constructor. Write set and get functions for all the four members of the class. Overload these operators: 1. Extraction operator >> : Prompt the user for hours, minutes, seconds and for am/pm and initialize the structure. Left operand istream object and right operand MyTime2. Assignment = : Assign the right object to the left object. Both operands are of type MyTime.3. Insertion << : Print the time in the format HH:MM SS PM. Left operand of type ostream and right operand of type MyTime. this in c++.Create a class called Point which will have 2 co-ordinate value x & y and will be able to calculate the distance between two points. Write appropriate constructor and method of the class. Create another class called Shape, which takes different number of points to create a triangle, rectangle and circle. And also able to calculate the area and perimeter for the different shapes. Write the appropriate overloading method for this shape class. Write appropriate main function to test the shape class. (Use C++ )Create a constructor named Exam that assigns "Good luck" to a previously declared String variable named message. Create an empty overloaded constructor for the Exam class with two (2) String parameters named period and level. Declare a double-type accessor named getPrice that returns the value of price. Declare a boolean-type accessor named isFinished that returns the value of status. Declare a class named Midterm that inherits from the class named Exam. Create three (3) class declarations to show multiple levels of inheritance. Use the classes named Exam, Midterm, and Essay. Create a constructor named Midterm that prints "Exam has started." using println(). Its first statement should be a call to a constructor in the parent class. Given the base class named Quiz and the derived class named Essay, write a statement to show inheritance between these classes.

Design and implement a class called train, which has at least the following: At least the following attributes (you can include others): metroID stationNum which keeps track of the station that the train is at. iii. direction which keeps track of the direction the train is travelling in. passTotal which keeps track of the number of passengers currently on the train. A default constructor which sets the metroID to a random number between 1 and 1000, the station number to 0, the direction (int), and the passTotal to 0 (train is empty). A constructor with one parameter; the parameter is the metro id. The constructor assigns the passed integer to the metroID attribute; the rest of the attributes are set as described in the default constructor. Accessor methods for each attributes. Mutator methods for each attributes. nextStation(int lastStation) which determines…Question Create a class called Quadratic for performing arithmetic on and solving quadratic equations. A quadratic equation is an equation of the form ax2 + bx + c = 0 Where a !=0. Use double variables to represent the values of a, b, and c and provide a constructor that enables objects of this class to be initialized when they are created. Give default values of a = 1, b = 0, and c = 0. Create a char variable called variable to represent the variable used in the equation and give it a default value of x. The constructor should not allow the value of a to be 0. If 0 is given, assign 1 to a). Provide public member functions that perform the following tasks. add—adds two Quadratic equations by adding the corresponding values of a, b, and c. The function takes another object of type Quadratic as its parameter and adds it to the calling object. subtract—subtracts two Quadratic equations by subtracting corresponding values of a, b, and…Create a class called Point which will have 2 co-ordinate value x & y and will be able to calculate the distance between two points.
