biilder1.java

郭克华j2ee高级框架实战教学视频源代码 这个是比较值得一看的 由郭克华博士在总结多年Java培训的基础上

package builder;

import java.awt.Panel;

//由四个小模块组成
class Builder implements IBuilder{//负责各个模块的生成
	public Panel getPanel1(){	//以后修改时，只需要修改相应的函数
		Panel p1 = null;
		//建造p1
		return p1;
	}
	public Panel getPanel2(){
		Panel p2 = null;
		//建造p2
		return p2;
	}

		Panel p3 = null;
		//建造p3
