这个文件里面包含了java设计模式的一些例子讲解

package com.javapatterns.command.audioplayer;

import java.util.Vector;

public class MacroAudioCommand implements MacroCommand
{
     private Vector commandList = new Vector();

     public void add(Command toAdd)
     {          
		commandList.addElement(toAdd);
     }

     public void remove(int index)
     {
		commandList.remove(index);
     }

     public void remove(Command toRemove)
     {
		commandList.removeElement(toRemove);
     }

     public void execute() 
     { 
		Command nextCommand;

		for (int i=0; i < commandList.size(); i++)
		{
			nextCommand = (Command) commandList.elementAt(i);
			nextCommand.execute();
        }
     } 
}
