Analysis: Q1: There are common attributes and methods between kids and trainers. What is the best choice for designing and writing the codes of these two classes? Explain your answer. Q2: Draw a simple class diagram showing only relationships between the classes. public class Kid { private static int idStatic = 0; private int id; private String name; private int age; private char gender; public Kid(String name, int age, char gender) { super(); this.id = idStatic++; this.name = name; this.age = age; this.gender = gender; } public static int getIdStatic() { return idStatic; } public int getId() { return id; } public String getName() { return name; } public int getAge( ) { return age; } public char getGender() return gender; } @Override public String toString() { return "Kid [id=" + id + ", name=" + name + } } Trainer.java age=" + age + ", gender=" + gender + "]"; public class Trainer { private static int idStatic = 0; private int id; private String name; private int age; private char gender; private double salary; public Trainer(String name, int age, char gender, double salary) { super(); this.id = idStatic++;; this.name = name; this.age = age; this.gender = gender; this.salary = salary; } public static int getIdStatic() { return idStatic; } public int getId() { return id; } public String getName() { return name; } public int getAge( ) { return age; } public char getGender( ) { return gender; } public double getSalary() { return salary; } @0verride public String toString() { return "Trainer [id=" + id + ", name=" + name + age=" + age + " gender=" + gender + ", salary=" + salary + "]"; } } Group.java import java.util.ArrayList; public class Group { private static int staticNumber = 0; private int groupNumber; private Trainer trainer; private String sportName; private ArrayList < Kid > kids; private final static int MAX_LIMIT = 10; public Group(Trainer t, String sport) { groupNumber = staticNumber++; this.trainer = t; this.sportName = sport; kids = new ArrayList < > (); } public static int getStaticNumber() { return staticNumber; } public int getGroupNumber( ) { return groupNumber; } public Trainer getTrainer() { return trainer; } public String getSportName() { return sportName; } public ArrayList < Kid > getKids() { return kids; } public boolean addKid(Kid k) { if (kids.size( ) < MAX_LIMIT) { kids.add(k); return true; } else { return false; } } public boolean removeKid(Kid k) { return kids.remove(k); } }
