Complete clone (copy constructor portion), scale, and toString functions for Composite class. Note that I have provided you a clone function and a skeleton for a copy constructor. Complete the copy constructor. Note the hints in the toString function. In JAVA

import java.util.Scanner; public class Composite extends Polyhedron { /** * Collection of polyhedra of which * this composite polyhedron is composed */ private Polyhedron[] polyhedra; /** * Default Constructor */ Composite() { super("Composite"); polyhedra = null; } /** * Copy Constructor */ Composite(Composite src) { super("Composite"); } /** * Read all component polyhedra * * @pre polyhedra == null * && numPolyhedra == 0 */ public void read(Scanner scanner) { int numPolyhedra = scanner.nextInt(); polyhedra = new Polyhedron[numPolyhedra]; for (int i = 0; i < polyhedra.length; i++) { polyhedra[i] = Polyhedron.createAndRead(scanner); boundingBox.merge(polyhedra[i].getBoundingBox()); } } public Polyhedron clone() { return new Composite(this); } public void scale(double scalingFactor) { } /** * Scale all polyhedra */ public String toString() { StringBuilder bld = new StringBuilder(); bld.append(super.toString()); // Start your toString code here //end your toString code here return bld.toString(); } }
