增强for循环遍历HashSet

package cn.bdqn.chatpterone.keben;

import java.util.*;

public class TestHanshSet {
    public static void main(String[] args) {
        //创建4个狗狗对象
        Dog ououDog = new Dog("欧欧","雪瑞纳");
        Dog yayaDog = new Dog("亚亚","拉布拉多");
        Dog meimeiDog = new Dog("美美","雪瑞纳");
        Dog feifeiDog = new Dog("菲菲","拉布拉多");
        //2创建ArrayList集合对象并把4个狗狗对象放入其中
        Set dogs = new HashSet();
        dogs.add(ououDog);
        dogs.add(yayaDog);
        dogs.add(meimeiDog);
        //dogs.add(2,feifeiDog);
        //输出集合中狗狗的数量
        System.out.println("共计有"+dogs.size()+"条狗狗");
        //通过遍历集合显示各条狗狗信息
        System.out.println("分别是：");
        System.out.println("***********************");
        //删除狗狗操作
        dogs.remove(0);
        dogs.remove(meimeiDog);
        for (Object object : dogs) {
            System.out.println(((Dog) object).getName()+((Dog) object).getStrain());
        }
//两个都可以遍历
        for (Dog object : dogs) {

System.out.println(object.getName()+object.getStrain());
        }
        System.out.println("***********************");
        if(dogs.contains(meimeiDog)){
            System.out.println("集合中包含美美信息");
        }
        else{
            System.out.println("集合中不包含美美信息");
        }
    }
}

因为HashSet没有get方法，无法得到数组元素的值，只能通过加强for循环

下面是我定义的Dog类

package cn.bdqn.chatpterone.keben;

public class Dog extends Pet{
    private String strain;
    /**
     * 有参构造方法
     * @param name 昵称
     * @param strain 性别
     */
    public Dog(String name,String strain){
        super(name);
        //super(name);
        this.strain = strain;
    }
    public String getStrain(){
        return strain;
    }
    public void print(){
        super.print();
        System.out.println("我是一只"+this.strain+"。");
    }

}
package cn.bdqn.chatpterone.keben;

public class Pet {
    /**
     * 宠物类、狗狗类和企鹅类
     */
    private String name = "无名氏";
    private int health = 100;
    private int love = 0;
    /**
     * 无参构造方法
     */
    public Pet(){
        health = 95;
        System.out.println("执行宠物的无参构造方法");
    }

    /**
     * 有参的构造方法
     */
    public Pet(String name){
        this.name = name;
    }

    public String getName(){
        return name;
    }
    public int getHealth(){
        return health;
    }
    public int getLove(){
        return love;
    }
    /**
     * 输出宠物信息
     */
    public void print(){
        System.out.println("宠物的自白：\n我的名字叫："+this.name+",我的健康值是"+this.health+"我" +
                "和主人的亲密度是"+this.love);

    }

}
