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:

- Write a class CircularArrayQueue such that all the following methods are implemented: 1. enqueue 2. dequeue 3. first 4. isEmpty 5. size 6. toString1/ Write a BankAccountTester class whose main method constructs a bank account, deposits $1,000, withdraws $500, withdraws another $400, and then prints the remaining balance. Also print the expected result 2/ Implement a class Employee. An employee has a name (a string) and a salary (a double). Provide a constructor with two arguments public Employee(String employeeName, double currentSalary) and methods public String getName() public double getSalary() public void raiseSalary(double byPercent) These methods return the name and salary, and raise the employee's salary by a certain percentage. Sample usage: Employee harry = new Employee("Hacker, Harry", 50000); harry.raiseSalary(10); // Harry gets a 10 percent raise Supply an EmployeeTester class that tests all methods. 3/Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in…this code is in java.Explore the given classes. Implement a getter method on the WasteRobot class with the following method signature public ArrayList<Waste> getWasteBin(String wasteType) The method should return the proper waste bin based on the passed wasteType.
