Do the following program in Java Eclipse. Java Class that can be used to create a Fruit object as described below: A fruit has - a: - Date of Harvest -Color -Weight -Number of seeds a. Add all instance variables. b. The class must have getters and setters for all instance variables. c. The class must have two constructors, a no-args and a constructor that receives input for each instance variables. d. The parent class is abstract. e. its 1 abstract method and has toString() method f. its 2 children (concrete) also have toString() methods.
Write a java program Write a class named Employee with name and salary as private data fields. Add a constructor with both parameters. Write a class named Manager which unherits the Employee class. Add an instance variable, named department, of type String and 15 private. Add a constructor in the subclass class and a toString () method that prints the manager's name, department, and salary [Hint: Add a tastanel) method in the super class as well]. Create objects of Manager and Employee dass
use java (ArrayList, inheritance, polymorphism, File I/O and basic Java) Student class: First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information, and all of these should be defined as Private: A first name (given name) A last name (family name/surname) Student number (ID) – an integer number (of type long) The Student class will have at least the following constructors and methods: (i) two constructors - one without any parameters (the default constructor), and one with parameters to give initial values to all the instance variables of Student. (ii) only necessary set and get methods for a valid class design. (iii) a reportGrade method, which you have nothing to report here, you can just print to the screen a message “There is no grade here.”. This method will be overridden in the respective child classes. (iv) an equals method which compares two student objects and returns true if they…
Below we have class diagrams with three classes for a simple java based parking management class. Use the classes below to write java code for classes :a parking observer class (that implements an observer pattern) , a transaction manager class and a parking lot class(subject to the observer). Use the class diagram and java class to implement it. You should use an observer pattern to implement your code.The main goal is to implement the following - Once a car enters (in an entry-scan only lot) or leaves (in an entry-scan and exit-scan lot), then the ParkingObserver will be updated, and then can register the charge with the parking system via the TransactionManager’s park() method
The Doctor program described in Chapter 5 combines the data model of a doctor and the operations for handling user interaction. Restructure this program according to the model/view pattern so that these areas of responsibility are assigned to separate sets of classes. The program should include a Doctor class with an interface that allows one to obtain a greeting, a signoff message, and a reply to a patient’s string. To implement the greeting, define a method named greeting for the Doctor class. To implement the signoff message, define a method named farewell for the Doctor class. Both greeting and farewell should return a string with a greeting or farewell message respectively. The reply function is defined for you, it should be added as a method for the Doctor class. The rest of the program, in a separate main program module, handles the user’s interactions with the Doctor object. Develop this program with a terminal-based user interface. Note: The program should output in the…
Java program * Interfaces 1. Modify the class Rectangle to implement the Comparable interface, as shown in the following UML class diagrams. Apply the required changes in the class’s header.2. Then, in the Rectangle class override the method compareTo(), so if this object’s area is greater than the specified (given through the parameter) object’s area return 1, if it is less than return -1, and 0 otherwise. 3. Create a test class named Test2. Then complete the following tasks: a. Create an ArrayList and add to it 4 Rectangle objects with different width and height values. b. Print out the elements of the ArrayList. c. Sort the elements of the ArrayList using the static method sort of the class java.long.Collections. This would be possible only, if you implemented the method compareTo() correctly in the Rectangle class. d. After sorting the elements of the ArrayList, print the elements again. 4. Run the Test class. Here is the rectangle's class program public class Rectangle extends…
a) Implement a class Point with three attributes, x, y, and z.b) Implement an init method with an optional parameter type: 1) Set the default value of x, y, and z to 0.c) Implement a display method to print the values of x, y, and z as the example output below.d) Instantiate two objects of type Point, one with arguments,1, 2, and 3, and the other one without any arguments.e) Call display() to print x, y, and z. Example Output(x, y, z): (1, 2, 3)(x, y, z) : (0, 0, 0)
Write a java program to create methods to compute n!, nCr and nPr. Use inheritance, constructors and this keyword to create object. (write a code without using inbuilt methods like sort, avg etc). Draw a flow chart for the code
Draw an inheritance hierarchy for students at a university. Use Student as the superclass of the hierarchy, then, extend Student with classes Undergraduate Student and Graduate Student. Continue to extend the hierarchy as deep (i.e., as many levels as possible). For example, Freshmen, Sophomore, Junior, and the Senior might extend Undergraduate Student and Doctoral Student and Masters Student might be subclasses of Graduate Students. After drawing the hierarchy, discuss the relationships that exist between the classes. [Note: You do not need to write any code for this exercise].
