client.java.svn-base

这个是我做j2ee培训时候自己整理和编写的设计模式的学习例子

package org.hyq.visitor;

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

public class Client {

	public static void main(String[] args) {
		Visitor visitor = new ConcreteVisitor();
		StringElement stringE = new StringElement("I am a String");
		visitor.visitString(stringE);
		Collection list = new ArrayList();
		list.add(new StringElement("I am a String1"));
		list.add(new StringElement("I am a String2"));
		list.add(new FloatElement(new Float(12)));
		list.add(new StringElement("I am a String3"));
		visitor.visitCollection(list);
	}

}
