内部类在迭代器设计模式中的应用

迭代器设计模式

package com.hephec;

public class MyContainer{

private Object[] items;

pirvate int size=0;

public Iterator iterator(){

return new LocalIterator();

}

private class LocalIterator  implements Iterator{

private int current=0;

public boolean hasNext(){

return current<MyContainer.this.size;

}

public Object next(){

return MyContainer.this.items[current++];

}

}

}

//interface

public interface Iterator{

public boolean hasNext();

public Object next();

}
