- Create a TestTriangle class in an individual .java file. In the main method,(1) Create a Triangle object with default base and height values.(2) Create a Triangle object with specified base = 3 and height =4.Create 5 objects of class Product, input its product code, name and quantity and write into the FILE. Later, display the data of all objects by reading from the FILE till the end of the file. Also, check if any product has quantity zero? [Write a class, XXXX_TestVehicle, which does the following:1. Creates one Car object from information entered by the user.2. Creates one Truck object from information entered by the user.3. Creates an Array of Vehicles that can hold 10 objects.4. It creates up to 10 Vehicles objects from information entered by the user
- Write a program that contains two classes a Main class and a Student class: • • The Student class has three data fields which are: name, GPA, and SID. It has a constructor that takes SID as a parameter. The Main class is used to declare objects from the Student class. The Main method should take student of type Student then display student ’ ’ s data from the console, store them in an object s data in the console.1. Create a python file with a class called "Mobile ()" which will allow us to create new mobile phone objects. 2. Each phone has 4 attributes: make model OS color 3. As there are many things a mobile phone can do create at least four methods the phone can do, examples can be receiving a call, playing a video etc...Within the methods, use print statements to reflect the actions. One Method should use more than one attribute in its print statement 4. Create a separate python file to call the Mobile() class and create at least 3 phone objects. 5. After creating the objects, let each phone perform at least two of the methods and printthem on the screen 6. Add comments to both files to explain your processCreate three files: Student.java - Abstract Class definition ENGRStudent.java - Derived Class definition Client.java - Contains main() method (1) Implement the abstract Student class with the following specifications: 3 private members String name int ID int yearAdmitted 1 constructors (public) A constructor with that accepts the student’s name, ID, and yearAdmitted as arguments. These values should be assigned to the object’s name, ID, and yearAdmitted fields. 2 public member methods A method named toString() that returns the values of name, ID, and yearAdmitted with String data type A abstract method name getRemainingHrs with int data type (2) Implement the derived class ENGRStudent class with the following specifications: 3 final private members with the following values : int MATHSCHRS=32 int MAJOR_HRS=66 int GenEdHrs=29 3 private members: int mathScHrs; int majorHrs; int GenEdHrs; 1 constructors (public) A constructor that accepts the student’s name, ID, and yearAdmitted…
- Write another Java class named Patient that contains: ■ A private integer data field called id. ■ A private static integer data field called numberOfPatients that counts the number of Patient objects created (default value 0). ■ A private String data field called name. ■ A private Address variable called address. ■ A private File variable called file that refers to a database.txt file. ■ A constructor that creates a patient object with specified name and address. Note that the id of patients is auto-incremented. If 3 patients are created the first one would have id 1, the second id would be 2 and the third id 3. ■ A static method getNumberOfPatients() that returns the number of patients. ■ A method getId() that returns the patient’s id. ■ A toString() method that returns a one-line description of the patient. ■ A savePatientToFile() method that is called every time a new patient object is created to save the patient information (patient object) to the database file.1. Create a new Java class named Student that has the following fields o yearOfAdmission - The yearOfAdmission field is an calendar data type that holds the year of admitting the student (e.g. 2021) o Name - The name field is a String object that holds the name of the student (e.g. “Ahlam") o Address – The address field is a String that holds the address of the student (e.g. “AlHail”) 2. In addition to that, the student class should have the following methods. o Constructor - The constructor should accept yearOfAdmission, name, and Address as arguments ▪ These values should be used to initialize the year of admitting student, name of the student, and Address fields. o Getter Methods - Write three accessor (getter) methods to get the values stored in an object's fields ▪ getYear(), getName(), get Address () Below code is a hint to get you started. public class Student { private int yearOfRegistrn; private String Name; private String Address; // Constructor public…What is a constructor? A A class designed especially to construct a Java object. B A data field used to build new data types. C A method that we use to initialize new objects of a class. D One of Java's primitive data types.
