集合中存储自定义对象:
package attention; import java.util.ArrayList; import java.util.Collection; import java.util.Iterator; public class Main_7 { public static void main(String[] args) { Collection coll=new ArrayList(); coll.add(new Person("List1",21)); coll.add(new Person("List2",22)); coll.add(new Person("List3",23)); // 取出元素 Iterator it=coll.iterator(); while(it.hasNext()) { Person p=(Person)it.next(); System.out.println(p.getName()+":"+p.getAge()); } } }
package attention; public class Person { private String name; private int age; // alt+shift+s 获得get、set方法 public Person() { super(); // TODO Auto-generated constructor stub } public Person(String name, int age) { super(); this.name = name; this.age = age; } /** * @return the name */ public String getName() { return name; } /** * @param name the name to set */ public void setName(String name) { this.name = name; } /** * @return the age */ public int getAge() { return age; } /** * @param age the age to set */ public void setAge(int age) { this.age = age; } }
