QUESTION 1 What is the problem with the following interface declaration? public interface MenuItem ( public double maxPrice = 12; public double getPrice (); } O maxPrice is declared as a double, but its value does not have a decimal point O It's actually okay -- nothing is wrong O There should be a method implementation for getPrice () O The get Price () method has the wrong return type QUESTION 2 Assume that we have a very well balanced binary search tree, i.e., a tree that has roughly the same number of right and left child nodes. What is the run time associated with searching for a value in this tree? O O(log n) O O(n?) O O(n) O O(n* log n) QUESTION 3 A Java Predicate Lambda O accepts one or more parameters and returns a boolean value O accepts a single parameter and returns a boolean value O accepts a single parameter, but does not return a value O does not have a return type

I need help fix this Java code described below so that it can be followed in the image below package classPackage; import interfaces.RatInterface; public class Rat implements RatInterface { private int ratEnergy = 5; @Override public String move() { // TODO Auto-generated method stub returnnull; } @Override publicint getAliveState() { // TODO Auto-generated method stub return 0; } @Override publicvoid refresh() { ratEnergy = 5; } @Override publicvoid wearDown() { ratEnergy -= 1; } @Override public String getId() { // TODO Auto-generated method stub returnnull; } }

True or False? Interface can be used to store a common method implementation.

write the definition of a class Counter containing: an instance variable counter of type int, initialized to 0 a method called increment that adds one to the instance variable counter. It does not accept parameters or return a value a method called get_value that doesn't accept any parameters. It returns the value of the instance variable counter. using python

Which is true? Group of answer choices A class can implement multiple interfaces A class can inherit from multiple classes A class can implement only one interface An interface can implement multiple classes

Which of the following cases is most like the strategy pattern? A. If you have an interface called Duck, and have many ducks that implement the duck interface. All of these ducks must have the behaviour "quack" but for some ducks, like a Mallard, this must result in a quack, where for a rubber duck it must result in a squeak. We decide to delegate the quack method to another interface, which can be implemented either in a concrete class that returns a quack or a concrete class that returns a squeak. B. If we have an interface called Duck. We need to give an object to a user that can quack like a duck. All we have is Turkeys. We create a special class that implements the duck interface, and to implement the quack method we simply call the turkey’s gobble method. C. None of these are like the strategy pattern. D. We have a large collection of Ducks. We want to look at them one by one and hear them quack. We write a piece of code that iterates through them all, and as we encounter...

This is for pygame Ball Class: The Ball class inherits from Drawable and it will draw a circle at its current location. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Class

Write a simple card game called WAR in C++ that uses a Card class to build a Deck class of 52 cards.Then use the Deck class to play. Only two people can play, one card is dealt face up and the highest value card wins the game, unless they're the same in, which case it's a tie. Here are the methods you will need to build; Deck class- public Deck(), public void refreshDeck(), public Card Deal(), public void shuffle(), public int cardsLeft(), public void showDeck(). Card class- public Card(), public Card(char r, char s), public int getValue(), public void showCard(). Remember to create seperate interface and implementation files for the C++ program. Use arrays to store values and not pointers for the Deck and Cards. .
