1. Read the compilation error in PetRecord.java and fix it by changing the method declaration

2. Add a public static petsWithNoName variable initialized to 0 in PetRecord and update its value in each constructor that does not set the pets name

3. In PetMain.java, follow the TODO instructions to add print statements that show the value of the petsWithNoName variable by direct class access and object access

public class PetMain { public static void main(String[] args) { // TODO: print the value of petsWithNoName by direct access via the class name PetName.java PetRecord[] pet = new PetRecord[10]; pet[0] = new PetRecord(); pet[1] = new PetRecord("Gruff"); pet[2] = new PetRecord(8); pet[3] = new PetRecord(4.6); pet[4] = new PetRecord("Rex", 12, 87.3); pet[5] = new PetRecord(5); pet[6] = new PetRecord(25.3); pet[7] = new PetRecord("Lassie"); pet[8] = new PetRecord("Brownie", 2, 15.6); pet[9] = new PetRecord(); // TODO: print the value of petsWithNoName by direct access via the class name // TODO: print the value of petsWithNoName for each of the 10 PetRecord objects in the array } }
