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()
{ return salary; }
}
FOR JAVA
Write a Java class named Book, which has a name, an author and a pub- lisher. This class must also have a static field (an array with length 100) which holds names of all constructed books, and a static method which returns the number of constructed books.
