動物類：

package DemoLearnTest.迭代器03;

public class Animal {
    private String site;
    private String name;

    public Animal(){

    }

    public Animal(String site, String name){
        this.site = site;
        this.name = name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public void setSite(String site) {
        this.site = site;
    }

    public String getSite() {
        return site;
    }

    public String getName() {
        return name;
    }
}
 

main函式：

package DemoLearnTest.迭代器03;

import java.util.ArrayList;
import java.util.Collection;
import java.util.Iterator;

public class Test {
    public static void main(String[] args) {
        Collection animal = new ArrayList();

        Animal aaa = new Animal();
        Animal bbb = new Animal();
        Animal ccc = new Animal();

        aaa.setSite("食肉動物");
        aaa.setName("老虎");

        bbb.setSite("雜食動物");
        bbb.setName("豬八戒");

        ccc.setSite("食草動物");
        ccc.setName("喜羊羊");

        animal.add(aaa);
        animal.add(bbb);
        animal.add(ccc);

        Iterator<Animal> it = animal.iterator();
        while (it.hasNext()){
            Animal an001 = it.next();
            System.out.println(an001.getSite() + "-" + an001.getName());
        }
    }
}
 

執行結果如下所示：
