- Java allows implementing multiple interfaces through a single class declaration statement such as: public class Student implements Comparable, Cloneable{ //code goes here }What is polymorphism in Java? It is when a program uses several different types of objects, each with its own variable. It is when a single variable is used with several different types of related objects at different places in a program. It is when a single parent class has many child classes. It is when a class has several methods with the same name but different parameter types.JAVA: According to this diagram, what is the relationship between the Ant and AntColony classes? Group of answer choices: A: AntColony derives from Ant B: Ant contains a reference to AntColony C: AntColony uses Ant objects D: AntColony is an interface that Ant implements
