print out is like Dogname d0 age 0 Dogname Lucky age 1 Dogna

print out is like

Dog-name: d0, age: 0

Dog-name: Lucky, age: 1

Dog-name: GG, age: 7

Dog-name: d1, age: 12

WolfDog-name: Juno, age: 5, meanness: 9001

WolfDog-name: wd, age: 1, meanness: 10

WolfDog-name: Venti, age: 5, meanness: 100

Dog Notes (also indicated by the arro a. The first three Dog constructors age: int -name: string call the fourth one Initialize with: age name \"do\" b. The first WolfDog constructor Dog (age:int) name- dl calls the second one. Dog (name:string) age 1 Dog (age:int,name:string) c. The second WolfDog toString0:string returns constructor calls the 2-arg Dog \"Dog-name: name, age: age constructor WolfDog meanness:int name \"wd WolfDog(meanness:int, ageint) WolfDog (meanness:int, ageint, name: String) toString0 returns: \"WolfDog-name: name, age: age meanness: value 1. Write the two classes exactly as shown in the class diagram. 2. Create another DogTester class in package prob3 and copy this code into it: package prob3; public class DogTester public static void main(String[ args) Dog d1. new Dog(); Dog d2 new Dog (\"Lucky\"); Dog d3 new Dog(7, \"GG\"); Dog d4 new Dog(12); WolfDog W1 new WolfDog (9001. 5, Juno Wolf Dog W2 new WolfDog (10, 1); WolfDog W3 new WolfDog(100, 5 \"Venti\"); System.out.println(d1 \"Vn d2 \"In\" d3 \"In\" d4 \"Vn\" \"In w3); W1

Solution

package prob3;

public class Dog {

   private int age;
   private String name;

   public Dog() {
       // TODO Auto-generated constructor stub
       this.age = 0;
       this.name = \"d0\";
   }

   /**
   * @param age
   */
   public Dog(int age) {
       this.age = age;
       this.name = \"d1\";

   }

   /**
   * @param name
   */
   public Dog(String name) {
       this.age = 1;
       this.name = name;
   }

   /**
   * @param age
   * @param name
   */
   public Dog(int age, String name) {
       this.age = age;
       this.name = name;
   }

   /*
   * (non-Javadoc)
   *
   * @see java.lang.Object#toString()
   */
   @Override
   public String toString() {
       return \"Dog-name:\" + name + \", age:\" + age;
   }

}

package prob3;

public class WolfDog extends Dog {

   private int meanness;

   /**
   * @param age
   */
   public WolfDog(int meanness, int age) {
       super(age);
       this.meanness = meanness;
       // TODO Auto-generated constructor stub
   }

   public WolfDog(int meanness, int age, String name) {
       super(age, name);
       this.meanness = meanness;

   }

   /*
   * (non-Javadoc)

   */
   @Override
   public String toString() {
       return \"Wolf\" + super.toString() + \", meanness:\" + meanness;
   }

}
