- Interfaces are used to define stronger is-a relationships because one class can inherit multiple interfaces. Ture or falseDoes it make sense to implement each and every method of an interface while doing so?Anonymous inner classes must implement interfaces or extend other classes in order to be considered complete.
- Interface This lab is a small demonstration of how interfaces work. Type up the code and submit the results. CODE public class InterfaceExample { public static void main(String[] args) { DemoClass myObj = new DemoClass(); myObj.myMethod(); myObj.myOtherMethod(); } public interface InterfaceOne { public void myMethod(); // interface method } public interface Interface Two { public void myOtherMethod(); // interface method } public class DemoClass implements InterfaceOne, Interface Two { public void myMethod() { System.out.println("Some text.."); } public void myOtherMethod() { System.out.println("Some other text..."); }A User class has an association link to a Service class, and calls its compute() method to do mathematical calculations. Because the computation takes time, it is better to first prompt a waiting message, which was not yet provided, to inform the user. However, the Service class is also used by other internal classes that do not need the message. Therefore, your job is to come out a way to provide the message without modifying the association relationship and the code of the Service class. What design pattern is a useful choice? Also,Show the new design in UML class diagram. Extra interfaces or classes can be added.Describe what advantages interfaces have over abstract classes.
