COVID-19 has effected whole world. People are interested in knowing current situation of COVID-19. You are required to write JAVA program for storing information in a Single way Linked List. Following JAVA classes are provided. // Node class public class COVIDDetail { public String country; public int activecases; public COVIDDetail next; } // linked List class public class COVIDList { COVIDDetail start=null; } You are required to add following methods to COVIDList class void add(COVIDDetail n) this method receives a node as argument and adds it to given list. Nodes are arranged in descending order with respect to number of cases. Note that you are not required to sort the list in fact while adding first find its appropriate position and then add given node to that position. void updateCases(String country_name , int cases) this method receives two arguments country name and cases (can have positive or negative value). Update active cases of those countries whose name matches with the one provided as argument, by adding activecases with cases (value provided as argument). String maxCases( ) returns name of country with maximum number of cases. void displayData( ) display data of least effected country. COVIDList covidFreeCountries( ) returns new list of those countries which are COVID free. Country whose active cases are 0 is considered to be COVID free.
