Lets say that class Laptop has been implemented. In order to compare two laptops a compareTo method that is in the comparable interface should be implemented. Which one of the following is the correct header for the method compareTo being added to the Laptop class 1. public static int compareTo(Object o) 2. public int compareTo(Laptop o) 3. public boolean compareTo(Object o) 4. public int compareTo(Object o) O 1 O 2 3

Write a java program to complete the following parts: Part-1: Create a class Car and perform the following: - Declare public instance variables (name, model, color) as (String, int, and String) respectively. - Define set() method to set a car's name, model, and color. Define show() method to print out the car's name, model, and color. Part-2: In the main method: Declare an array of the defined class Car with length 5. Create three objects from Car and add them into the array. Set the objects' values (name, model, color) using set method. Print out the object's values (name, model, color) using show method.

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…
Using the class diagram in the image below, write a small report (200- 300 words) on how to create customer, car, and parking lot classes for an object-oriented parking system using java.
Define an Animal method that updates the time to complete a particular behavior based on its name. Choose one of the following from the above choices (A, B, C or D within the code): public class Animal { // Other instance variables, constructors and methods // omitted for brevity // A public void updateTimeTakenForBehavior(String behaviorName, int timeToComplete) { for(int i = 0; i < this.behaviorList.length; i++) { Behavior tempBehavior = this.behaviorList[i]; if( tempBehavior.getBehaviorName().equals(behaviorName)) { tempBehavior.setTimeToComplete(timeToComplete); } } } // B public void updateTimeTakenForBehavior(String behaviorName, int timeToComplete) { for(int i = 0; i < this.behaviorList.length; i++) { Behavior tempBehavior = this.behaviorList[i]; if( !tempBehavior.getBehaviorName().equals(behaviorName) ) {…
