实验5：建造者模式
实验5：建造者模式
本次实验属于模仿型实验，通过本次实验学生将掌握以下内容：
1、理解建造者模式的动机，掌握该模式的结构；
2、能够利用建造者模式解决实际问题。
[实验任务一]：计算机组装
使用建造者模式，完成下述任务：计算机组装工厂可以将CPU、内存、硬盘、主机等硬件设备组装在一起构成计算机，计算机的类型可以是笔记本，也可以是台式机。
实验要求：
1. 画出对应的类图；
2.提交源代码；
3.注意编程规范。
1.Builder
public abstract class Builder {
Computer computer = new Computer();
abstract public void buildZhuJi();
abstract public void buildYinPan();
abstract public void buildCpu();
abstract public void buildNeiCun();
public Compture getCompture(){
return compture;
}
}
① Compture
public class Compture {
private String cpu;
private String neiCun;
private String yinPan;
private String zhuJi;
public String getZhuJi() {
return zhuJi;
}
public void setZhuJi(String zhuJi) {
this.zhuJi = zhuJi;
}
public String getYinPan() {
return yinPan;
}
public void setYinPan(String yinPan) {
this.yinPan = yinPan;
}
public String getNeiCun() {
return neiCun;
}
public void setNeiCun(String neiCun) {
this.neiCun = neiCun;
}
public String getCpu() {
return cpu;
}
public void setCpu(String cpu) {
this.cpu = cpu;
}
}
2. Factory
public class Factory {
private Builder comptureKind;
public void setCompture(Builder kind) {
this.comptureKind = kind;
}
public Compture construct(){
comptureKind.buildCpu();
comptureKind.buildYinPan();
comptureKind.buildZhuJi();
comptureKind.buildNeiCun();
return comptureKind.getCompture();
}
}
3. LapBuilder
public class LapBuilder extends Builder{
@Override
public void buildZhuJi() {
compture.setZhuJi("LZJ");
}
@Override
public void buildYinPan() {
compture.setYinPan("LYP");
}
@Override
public void buildCpu() {
compture.setCpu("LC");
}
@Override
public void buildNeiCun() {
compture.setNeiCun("LNC");
}
}
4. Store
public class Store {
public static void main(String[] args) {
Builder lap;
Factory factory=new Factory();
for (int i = 0; i < 2; i++) {
if(i==1)
lap = new LapBuilder();
else
lap=new TaiShiBuilder();
factory.setCompture(lap);
factory.construct();
System.out.println(lap.getCompture().getCpu());
System.out.println(lap.getCompture().getNeiCun());
System.out.println(lap.getCompture().getYinPan());
System.out.println(lap.getCompture().getZhuJi());
}
}
}
5. TaiShiBuilder
public class TaiShiBuilder extends Builder{
@Override
public void buildZhuJi() {
compture.setZhuJi("TZJ");
}
@Override
public void buildYinPan() {
compture.setYinPan("TYP");
}
@Override
public void buildCpu() {
compture.setCpu("TC");
}
@Override
public void buildNeiCun() {
compture.setNeiCun("TNC");
}
}
