6. Create a Counter class with a private count instance variable and two methods. The first method: synchronized void increment() tries to increment count by 1. If count is already at its maximum of 3, then it waits until count is less than 3 before incrementing it. The other method: synchronized void decrement() attempts to decrement count by 1. If count is already at its minimum of 0, then it waits until count is greater than 0 before decrementing it. Every time either method has to wait, it displays a statement that saying why it is waiting. Also every time increment or decrement occurs, the counter displays a statement that says what occurred and shows count's new value. increment() and decrement() will be executed by 2 separate threads. Use sleep(500) between each count print.

Change the Fraction class so that its instance variables (numerator and denominator) are hidden (i.e. private). Check that the client class (after this change) will now not compile. Why does it not compile? Provide the changes to the Fraction class and the TestFraction class such that the program can work with the private instance variables by implementing appropriate accessor and mutator methods. import java.util.Scanner;//test programpublic class testfraction{public static void main(String[] args) {//create a Scanner objectScanner in = new Scanner(System.in);//create new fractionFraction frac = new Fraction();//declare numerator and denominatorint n=1,d;System.out.print("Enter Fraction's Numerator: ");//input numeratorn = in.nextInt();System.out.print("Enter Fraction's Denominator: ");//input denominatord = in.nextInt();//loop execute until the numerator is negativewhile(n>=0){//call input with n and dfrac.input(n, d);//call displayfrac.display();System.out.print("Enter…
Write a class CountObject which has a method namenumberfoObjects() which returns the number of objects been created ofthat class. Also write a class that will create few objects of CountObjectclass and show the count. (Hint: you have to use static variable inCountObject class).

please write code in java Create a right triangle class with instance variables(double) for sideA, sideB and the hypo. write three constructors -the 2-param version assigns to sides A and B respectively. the 1-param version assigns the same value to both sides. the 0-param version assigns 10.0 to each side. the constructor also computes the hypotenuse based on the other two sides and saves that in the hypotenuse variable. Create accessors for all three variables. Write a toString() that will print/label the three sides. write some main code to create three instances of your class, one to test each of your constructors. you can input values or use fixed values. Display each instance using an implicit toString() call.
Consider this scenario, a mehtod in some class needs to access a data field in another class, here are two possible implementations: public class Process { /* * Check if student qualifies for financial help */ void check(Student student) { //.... } /* * Check if student qualifies for financial help */ void check(double studentGPA) { //.... }} In class Process, which check method you think is better, why? In other words, should we pass the object to the method or just the data member it needs? Disucuss the Pros and Cons of each approach (if any). Assume class Student has a mehod called getGPA( ).
Make a class names Foo Add a class variable to foo called x and initialize it to 5 Add an instance variable to foo called y and initialize it to 100 Make an instance of the class, call it f Using f, print out the value of x Print out the value of y Hint: remember that class variables are the ones where their value is the same for all instances/clones. And instance variable (which you declare inside the __init__ method with the self. preface, are unique to each clone. When you print a class variable the proper way is to use classname . (for example Foox) and when you print an instance variable you use the instance handle (for example f.y.)

Be careful: The result of compareTo must be an int.
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
In this challenge, we'll implement an Account class along with two derived classes, Savings and Current. Problem Statement# Write a code that has: ● A parent class named Account. ○ Inside it define: ■ a protected double member balance ■ public void Withdraw(double amount) ■ public void Deposit(double amount) ■ public void printBalance() ● Then, there are two derived classes ○ Savings class ■ has a private member interestRate set to 0.8 ■ Withdraw(double amount) deducts amount from balance with interestRate ■ Deposit(double amount) adds amount in balance with interestRate ■ printBalance() displays the balance in the account ○ Current class ■ Withdraw(double amount) deducts amount from balance ■ Deposit(double amount) adds amount in balance ■ printBalance() displays the balance in the account Input# ● In the Savings class, balance is set to 50000 in the parametrized constructor ● In the Current class, balance is set to 50000 in the parametrized constructor Output# Balance before…
In this java assignment, we will be creating a paystub for an employee using classes, files, getters, and setters. Each file should only have one class and the class should share the same name as the file. We are going to implement the following classes: Employee - This class represent the employee. It needs the following fields exposed via getters and setters: Employee ID (hard code it to 1) First name, last name, middle initial Address, city, zip Phone, email Hourly rate PayPeriod - This class represents an employee's payment information. An employee will eventually have more than one pay period. It needs the following fields exposed via getters and setters: Pay period Id (hard code to 123456) Employee Id Start date, end date Number of hours PayrollManager - This class provides the functionality we need to compute and display the payroll. It should implement the following methods: double CalculateGrossPay (Employee, PayPeriod) - this should return the total gross for the…
Your task is to implement the Name class. This class represents a person's name. It has three instance variables representing the first, last and middle name (all are string variables). A character instance variable representing a separator (to be used for printing purposes) is also part of the class. The only valid separators we can have are a comma (,), a dash (-), and a pound symbol (#). In addition, a nickname instance variable (string) keeps track of the person's nickname (if any). The output have to match with the image. Write code in JavaScript
