You are given the following class and the client class. Examine the code and provide the output of the client class. Explain the intention of the code and comment if the code output matches the intended use of the code. Explain any mismatch between intention and actual code output. Find the problem in this code and explain what you would do to solve the problem. The Person class is shown in the UML class diagram as follows. System.out.println("Name: System.out.println("Age: System.out.println("Weight: " + weight + " kg"); " + name); " + age + " years"); Person - name: String + setName(String newname): void + getName( ): String + writeOutput ( ): void + equals (Person otherPerson): boolean /** This is the class that can be used for the client class */ public class Twin { private Person first, second; public Twin(Person firstPerson, Person secondPerson) { first = firstPerson; second = secondPerson; } public Person getFirst() { return first; } public Person getSecond() { return second; } /** The writeOutput() in Person as follow. Public void writeOutput() { System.out.println(“Name: “ + name); } */ public void writeOutput() { System.out.println("First person of the twin:"); first.writeOutput(); System.out.println("\nSecond person of the twin:"); second.writeOutput(); } } /** A client program to use the class Twin */ public class TwinDemo { public static void main(String[] args) { Person goodPerson = new Person("Michael"); Person sibling = new Person("John"); Twin t1 = new Twin(goodPerson, sibling); } }
