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,…How to fix these erros LocalResource.java:153: error: LocalResource is not abstract and does not override abstract method getPay() in Person public class LocalResource extends Person { ^ LocalResource.java:160: error: incompatible types: String cannot be converted to int super(firstName, lastName, date); public class LocalResource extends Person { private static int idCounter = 0; private int id; private String sector; private String trn; public LocalResource(String firstName, String lastName, String trn, String date, String sector){ super(firstName, lastName, date); this.trn = trn; this.sector = sector; this.id = ++idCounter;} public String getSector() { return sector; } public void setSector(String sector) { this.sector = sector; } public int getId(){ return id; } public String getTRN(){ return Integer.toString(id +100000000); } public String getContact() { return "LocalResource#" +…
