Suppose we have the following system of classes: Class Beta has a no-argument constructor. Class Alpha inherits from class Beta and has a one argument constructor that takes an integer parameter. Class Gamma inherits from class Alpha and has a one argument constructor that takes a float parameter. All constructors should be passed the value four. Write appropriate Java code for this system of classes.

- 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++.JAVA write grading program for a class with the following grading policies. thers a total of 2 quizzes, each graded on the basis of 10 points. theeres is 1 midterm exam and one final exam, each graded on the basis of 100 points. final exam counts for 50% of the grade, the midterm counts for 25%, and the 2 quizzes together count for a total of 25%.

You will implement a translation system that can handle his diverse linguistic needs. To do that, you will write three classes (the name of each is bolded below). The Message class is at the core of the translation system. A Message stores a message and the dialect it's encoded into. A Dialect enum defines all supported dialects, where each dialect has its own set of rules governing the translation of messages. Additionally, the Message class maintains a running count of how many messages have been translated to each dialect at any point in time. Message exposes a public translate method that translates the original message into its specified dialect. It defines other private methods that handle the translation logic for each specific dialect. Note that a Message should not be considered translated until the first call to the translate method on…
- 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 Java program for given scenarios below: Create a class named 'Member' having the following members: Data members 1 - Name 2 - Age 3 - Phone number 4 - Address 5 - Salary It also has a method named 'printSalary' which prints the salary of the members. Two classes 'Employee' and 'Manager' inherits the 'Member' class. The 'Employee' and "Manager' classes have data members 'specialization' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a manager by making an object of both of these classes and print the same.In the board game Scrabble, each tile contains a letter, which is used to spell words in rows and columns, and a score, which is used to determine the value of words. The point of this exercise is to practice the mechanical part of creating a new class definition: Write a definition for a class named Tile that represents Scrabble tiles. The instance variables should be a character named "letter" and an integer named "value".
- Use BlueJ to write a java program that complete the following parts: Create a class named Employee and perform the following: Define private fields (E_name, E_age, E_department) as (String, int, and String) Define a class variable Salary that holds a constant value 10000. Define a parameterized constructor of the class Employee to initialize the values of (E_name, E_age, E_department)) as they are received in the parameters.In the board game Scrabble, each tile contains a letter, which is used to spell words in rows and columns, and a score, which is used to determine the value of words. The point of this exercise is to practice the mechanical part of creating a new class definition: Write a definition for a class named Tile that represents Scrabble tiles. The instance variables should be a character named "letter" and an integer named "value". Write a constructor that takes parameters named letter and value, and initializes the instance variables. Create getters for both of the attributes. (No setters, so that a Tile is immutable.) Implement the .toString() and .equals methods for a Tile. Your completed Tile class should work with this Main program (Links to an external site.) so that it produces sample output like shown at the end of the program.

- Novice: How can i access a main class objects from outside the function? / Better Alternative? If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber. What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that. i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.PLZ help with the following: In JAVA ABC Company helps its clients to find a quick and easy analysis for better investment decisions.
