are there any errors ? how many errors if there are any and with explanation 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; } }
- What is included in the method private void buildLetterTable() { implemented in the class AnagramsIN JAVA When is is necessary to create an object to call a method? A. When the method is an instance method. B. When the method has a return value. C. When the method is void. D. When the method is a static method.FOR JAVA Part I Create a Company class that has at least three properties. Part II Write proper constructor and other methods required for the class (get & set, toString etc.) Part III Write at least 5 different methods considering the applications of Company class. Your methods must handle exceptions. Part IV Write a Test class and use the methods written in Company class.
- True or False: An abstract method has no body.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. You must also implement its constructors (one constructor with parame- ters, one default constructor), toString method, getters and setters.*using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…
