address.java

这个是java编写的ARRAYLIST（动态数组）的实现源代码

/*import java.util.*; 

class Add{ 
public String name; 
public String address; 
Add(String name,String address){ 
this.name=name; 
this.address=address; 
} 
} 

public class Address { 
public static void main(String[] args){ 
Add a1=new Add("周接论","台湾新竹"); 
Add a2=new Add("六得话","香港尖沙嘴"); 
ArrayList v=new ArrayList(2); 
v.add(a1); 
v.add(a2); 
System.out.println("在这里输出Add对象的属性"); 
} 
}*/
import java.util.*; 

class Add{ 
public String name; 
public String address; 
Add(String name,String address){ 
this.name=name; 
this.address=address; 
} 
} 

public class Address { 
 
public static void main(String[] args){ 
Add a1=new Add("周接论","台湾新竹"); 
Add a2=new Add("六得话","香港尖沙嘴"); 
Add a3=new Add("周彦坤","河南新乡");
Collection v=new ArrayList(3); //将这个ArrayList对象赋给Collection对象的引用 
v.add(a1); 
v.add(a2); 
v.add(a3);
Iterator it=v.iterator(); 
while(it.hasNext())//迭代输出 
{ 
 Add a=(Add)it.next();//类型转换 
 System.out.println(a.name+":"+a.address);//打印输出 
} 
} 
}
