- Design an interface Polynomial that defines the following operations. This is your polynomial abstract data type. Specifically this interface should have the following method signatures: A method addTerm that takes a coefficient and a power (both integer numbers) and adds the resulting term to the polynomial. (This will enable you to build a polynomial term-by-term.) It should throw an IllegalArgumentException if a negative power is passed to it. A method removeTerm that takes a power and removes any and all terms in the polynomial with that power. A method getDegree that returns the degree of this polynomial. A method getCoefficient that takes a power and returns the coefficient for the term with that power. A method evaluate that takes a double-precision decimal number and returns a double-precision result. A method add that takes another Polynomial object and returns the polynomial obtained by adding the two polynomials. Any implementation should ensure that this method does not…Please help answer this Java multiple choice question. Assume you are a developer working on a class as part of a software package for running artificial neural networks. The network is made of Nodes (objects that implement a Node interface) and Connections (objects that implement a Connection interface). To create a new connection you call the constructor for a concrete class that implements the Connection interface, passing it three parameters: Node origin, Node target, and double weight. The weight is a double that is greater than or equal to 0, and represents how strongly the target node should weigh the input from the origin node. So with a weight of 0.1 the target node will only slightly weight the input from the origin, but with a weight of 725.67 the target node will strongly weight the input. The method throws an IllegalArgumentException. Which of the following are true? A. All of the above are true. B. The code:Connection c = new ConvLayerConnection(origin, target,…Give me a code example where you can decouple the classes with the help of Interface? II. Give a code example to show the difference between an abstract class and Interface? III. Give a code example to show the implementation of Abstraction Principle?
- I need the solution to this question using javado this with java15. True or false: a. An interface defines operation implementations. b. An aggregation implicitly defines a 1: n relationship. c. Navigability defines for implementation, which class keeps reference(s) to the other class. d. Composition means, that an object throws an exception when it is deleted.
- Explain the difference between the following implementations of class A.a. extending class A from class Bb. extending class A from parent abstract class Cc. class A implementing interface DComputer Science There are clearly some similarities in the implementations of Taxi and Shuttle that suggest use of inheritance to represent them. Introducing inheritance is the primary task of this assessment. -The Ezcab class, The Ezcab class maintains separate lists of taxis and shuttles and destinations with destination fares (you can hardcode destination fares). It has a lookup method that searches for a taxi/shuttle with a given ID. -The Taxi and Shuttle classes share some common attributes – location and destination. They also have some common methods – getLocation, getDestination, getStatus and setDestination. -Vehicle is the superclass of both Taxi and Shuttle. This class involves placing the common fields and methods into Vehicle and removing them from Taxi and Shuttle. -Modify Taxi and Shuttle class to indicate that it is a subclass of Vehicle. You can keep the id field in Vehicle class and getId,SetId methods. -Arrange for Taxi's constructor to call the constructor of…Define a class counterType to implement a counter. Your class must have a private data member counter of type int. Define a constructor that accepts a parameter of type int and initializes the counter data member. Add functions to: Set counter to the integer value specified by the user. Initialize counter to 0. Return the value of counter with a function named getCounter. Increment and decrement counter by one. Print the value of counter using the print function. Example output: Counter = 0. The value of counter must be nonnegative.
- Interfaces are used to define stronger is-a relationships because one class can inherit multiple interfaces. Ture or falsejava Create a Storage<T> abstract class. The class has abstract methods void print() which prints the object of the storage. The class has a non-abstract method add(T element) which adds the not-null element in the storage if the element is not already present. Create a class MyStorage which is a subclass of Storage.Answer in java
