Implement the following in java, write all classes need in the following application, in addition to demo class that contains main method to test your application A customer has already account with a particular Website (Mawdoo3). This account holds all data related to the user such as name, phone num, email. Mawdoo3 site applies a new button to validate your phone num, but they need to not affect the existing application. Instead, they need to build adapter that can access validate phone num service and make it available for Mawdoo3 customers. When a customer needs to perform a validate phone num, the account cannot access directly Mawdoo3 account detail, but instead it can access adapter to complete the transaction. Validation phone number process includes the following 1. There must be two underscores ) in the phone num Also Number of characters including underscores equal 13. a. if the customer's phone num is valid, the new service will return valid "phone num" and if not, the service will return "not valid" b. The application will print the returned message to the user

Class Circle  A Circle will have a radius. The class will be able to keep track of the number of Circle objects created. It will also hold the total of the circumferences of all the Circle objects created.  It will allow a client to create a Circle, passing in a double value for the radius into the Circle constructor. If the value for the radius that is passed in is 0 or negative, then the radius will be set to a value of 999. The constructor should add 1 to the count of the number of Circles created. The constructor should call a method to calculate the circumference and then add the circumference for that object to an accumulator. In addition to the constructor, the Circle class must have the following methods that return a boolean value: isCongruent(Circle c) – Compares two Circle objects to determine if they are congruent (radii are equal). isValid() – the radius may not be 0 or negative. equals (Triangle t) – compares two Triangle objects…
This project utilizes three new classes: · Word - an immutable class representing a word · Words - a class representing a list of Word objects · WordTester - a class used to test the Word and Words classes. WordTester (the application) is complete and only requires uncommenting to test the Word and Words classes as they are completed. The needed imports, class headings, method headings, and block comments are provided for the remaining classes. Javadocs are also provided for the Word and Words classes. Word The Word class represents a single word. It is immutable. You have been provided a skeleton for this class. Complete the Word class using the block comments, Javadocs, and the following instructions. 1. Add a String instance variable named word which will contain the word. 2. Complete the one parameter constructor to initialize the word instance variable. 3. Complete the getLength method to return the number of characters in the…
Please you can complete this part of my code almost done, I could not get the output. Please help me to fix this and add part 4 and 5. Part 4 instructions (please see image attached): Implement the relationship between interface and the classes as shown in the diagram below.
