阅读以下说明和Java代码，回答问题[说明]在某些系统中，存在非常复杂的对象，可以采用循序渐进的方式进行组合将小对象组合，成复杂的对象。以下实例展示了Builder(生成器)模式。该实例用来建立“文件”，文件内容包括：一个标题、一串字符以及一些有项目符号的项目。Builder类规定组成文件的方法，Director类利用这个方法产生一份具体的文件。图6-1显示了各个类间的关系。以下是Java语言实现，能够正确编译通过。[Java代码]//Builder. java文件public (1) class Builder {public abstract void makeTitle(String title);public abstract void makeString(String str);public abstract void makeItems(String[] items);public abstract Object getResult();}//Director. java文件public class Director{private (2) builder;public Director(Builder builder){this. builder = builder;}public Object construct(){builder.makeTitle("Greeting");builder.makeString("从早上到白天结束");builder.makeItems(new String[]{"早安", "午安",});builder.makeString("到了晚上");builder.makeItems(new String[]("晚安", "好梦",});return builder.getResult();}}//TextBuilder.java文件public class TextBuilder (3) Builder{private StringBuffer buffer = new StringBuffer();public void makeTitle(String title){buffer.append("『" + title + "』"\n\n");}public void makeString(String str){buffer.append('■' + str + "\n\n ");}public void makeItems(String[] items){for(int i = 0; i (4) ; i++){buffer.append('·' + items[i] + "\n");}buffer.append("\n");}public Object getResult(){return buffer.toString();}}//Main.java文件public class Main {public static void main(String[] args) {Director director = new Director(new TextBuilder());String result = (String)director. (5) ;System.out.println(result);
阅读下列说明和 C++代码,将应填入(n)处的字句写在答题纸的对应栏内。【说明】生成器( Builder)模式的意图是将一个复杂对象的构建与它的表示分离,使得同样的构建过程可以创建不同的表示。图 5-1 所示为其类图。【C++代码】#include #include using namespace std;class Product {private:? ??string partA, partB;public:Product() {?? }? ? ?voidsetPartA(const string}???? voidsetPartB(const string}//? 其余代码省略};class Builder {public:??????? （1）?? ;virtual void buildPartB()=0;??????? （2）?? ;};class ConcreteBuilder1 : public Builder {private:Product*?? product;public:ConcreteBuilder1() {product = new Product();???? }??? voidbuildPartA() {????? （3）????
