Question

In java program format

Submit your completed UML class diagram and Java file.

Part I: Create a UML diagram for this assignment

PartII: Create a program that implements a class called  Dog that contains instance data that represent the dog's name and age.  

• define the Dog constructor to accept and initialize instance data.  
• create a method to compute and return the age of the dog in "person-years" (note: dog age in person-years is seven times a dog's age).  
• Include a toString method that returns a one-line description of the dog
• Create a driver class called Kennel, whose main method instantiated and updates several Dog objects.

Answer 1

class Dog {
        private String name;
        private int age;

        public Dog(String aName, int aAge) {
                super();
                name = aName;
                age = aAge;
        }

        public String getName() {
                return name;
        }

        public int getAge() {
                return age;
        }

        public void setName(String aName) {
                name = aName;
        }

        public void setAge(int aAge) {
                age = aAge;
        }

        public int getAsHumanAge() {
                return age * 7;
        }

        public String toString() {
                return name + " is " + age + " old.";
        }
}

public class Kennel {
        public static void main(String[] args) {
                Dog d = new Dog("Bruno", 1);
                System.out.println(d);
                System.out.println("in Human age: "+d.getAsHumanAge());
        }
}
