Solve below java problem please.
You are given a list of Employee objects and you need to implement a method that returns the top n highest-paid employees.
class Employee {
private String name;
private double salary; public
Employee(String name, double salary) {
this.name = name;
this.salary = salary;
}
public String getName()
{ return name; }
public double getSalary()

- Fibonacci A fibonacci sequence is a series of numbers in which each number is the sum of the two preceding numbers. For example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on… For this, you will implement a class that takes a positive integer (n) and returns the number in the nth position in the sequence. Examples When n is 1, the returned value will be 0. When n is 4, the returned value will be 2. When n is 9, the returned value will be 21. come up with the formula and base cases Implementation Create a class Fibonacci with a public static method getValue. Create a Main class to test and run your Fibonacci class.// simulates a simple vending machine with operations to purchase drinks and check inventory.public class VendingMachine { // number of bottle in stock private int bottles; // initial inventory is 20 public VendingMachine(){ bottles = 20; } public void purchase(int amount){ bottles = bottles - amount; } public int getInventory(){ return bottles; } public void restock(int amount){ bottles = bottles + amount; } public void report(){ System.out.println("Inventory: " + bottles + " bottles"); } }Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.
- For the following class, write the code to create two different objects: public class Course{ private String courseCode; private int creditHours public Course(){ this.creditHours= 3; } public Course(String code, int h){ this.courseCode=code; this.creditHours =h; } } javaComputer Science Is there a way to rewrite this Java code differently? package application; public class Employee { private int eid; private String name; private String department; private float salary; private String mobileNo; public Employee() { super(); } public Employee(int eid, String name, String department, float salary, String mobileNo) { super(); this.eid = eid; this.name = name; this.department = department; this.salary = salary; this.mobileNo = mobileNo; } public int getEid() { return eid; } public void setEid(int eid) { this.eid = eid; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getDepartment() { return department; } public void setDepartment(String department) { this.department = department; } public float getSalary() { return salary; } public void setSalary(float salary) { this.salary = salary; } public String…public float method1(int z) { return (float) z; } // in another class we created an object of the first class and within in it: int y = tester.method1(); are there any errors ? with explanation please
