Question

You Do lt Using Static and Nonstatic fina7 Fields In this section, you create a class for the Riverdale Kennel Club to demonstrate the use of static and nonstatic final fields. The club enters its dogs in an annual triathlon event in which each dog receives three scores in agility, conformation, and obedience. 1. Open a new file in your text editor, and enter the first few lines for a DogTriathlonParticipant class. The class contains a final field that holds the number of events in which the dog participated. Once a final field is set it should never change. The field is not static because it is different for each dog. The class also contains a static field that holds the total cumulative score for all the participating dogs. The field is not final because its value increases as each dog participates in the triathlon, but it is static because at any moment in time, it is the same for all participants. public class DogTriathlonParticipant private final int NUM EVENTS; private static int totalCumul at ivescore = 0; 2. Add six private fields that hold the participating dog's name, the dog's score in three events, the total score, and the average score: private String name; private int obedienceScore; private int conformationScore; private int agilityScore; private int total; private double avg; continues)

//*****DogTripathlonParticipant.java********

//For part(11) codes are commented(you can uncomment accordingly to see output by yourself accordingly) and //output of all the part of part 11 is provided below along with screenshots

//(4) calculate total , avg and cumulative score
