Which of the above choices (A, B, C or D) creates a utility class named AnimalFinder that defines 1 static method that searches through a list of Animals and determines if an animal exists within that list? The method takes 2 arguments:
Which of the above choices (A, B, C or D) creates a utility class named AnimalFinder that defines 1 static method that searches through a list of Animals and determines if an animal exists within that list? The method takes 2 arguments:
- An Animal object that is being searched for
- an array of Animal objects to search through
A animal is assumed to be in the list if the animal's name and weight are equal.
// A
public class AnimalFinder {
public static boolean animalExists(Animal needle, Animal[] hayStack) {
for(int i = 0; i < hayStack.length; i++) {
Animal tempAnimal = hayStack[i];
if(
tempAnimal.getAnimalName().equals(needle.getAnimalName())
||
tempAnimal.getWeight().equals(needle.getWeight())
)
{
return true;
}
}
return false;
}
}
// B
public class AnimalFinder {
public static boolean animalExists(Animal needle, Animal[] hayStack) {
for(int i = 0; i < hayStack.length; i++) {
Animal tempAnimal = hayStack[i];
if(
tempAnimal.getAnimalName().equals(needle.getAnimalName())
&&
tempAnimal.getWeight().equals(needle.getWeight())
)
{
return true;
}
}
return false;
}
}
// C
public class AnimalFinder {
public static boolean animalExists(Animal needle, Animal[] hayStack) {
for(int i = 0; i < hayStack.length; i++) {
Animal tempAnimal = hayStack[i];
if( tempAnimal.getAnimalName().equals(needle.getAnimalName()))
{
return true;
}
if( tempAnimal.getWeight().equals(needle.getWeight()))
{
return true;
}
}
return false;
}
}
// D
public class AnimalFinder {
public static boolean animalExists(Animal needle, Animal[] hayStack) {
for(int i = 0; i < hayStack.length; i++) {
Animal tempAnimal = hayStack[i];
if(
tempAnimal.getAnimalName().equals(needle.getAnimalName())
&&
tempAnimal.getWeight().equals(needle.getWeight())
)
{
return false;
}
}
return true;
}
