我有4个课程
public class Book {
private String title;
private Autor[] autors;
private Collection<Chapter> chapters;
public Book(String title, Autor[] autors, Chapter[] chapters){
this.title = title;
this.autors = autors;
this.chapters = new ArrayList<Chapter> ();
}
}
在Book和Autor之间我有Agreggation，这就是为什么我在Book for Autor中使用数组
public class Autor {
private String name;
private Date dateBirth;
private String afiliation;
public Autor(String name, Date dateBirth, String afiliation){
this.name = name;
this.dateBirth = dateBirth;
this.afiliation = afiliation;
}
}
在Book和Chapters之间我有作文，这就是为什么我在Book中有一系列章节的原因
public class Chapter {
private String title;
private List <Section> sect;
public Chapter(String title, List sect){
this.title = title;
this.sect = sect;
}
public String getTitle() {
return title;
}
}
章节和章节之间我也有作文，这就是为什么我有一个部分列表
public class Section{
private String title;
public Section(String title){
this.title = title;
}
}
我现在的问题是当我想要实例化我不知道如何将参数作为集合，一系列autors提供
public class Test {
public static void main(String[] args) {
Autor[] autors = new Autor[]{
autors[0] = new Autor("Simin Lebanon", new Date(23, 07, 1974), "Lincoln University"),
autors[1] = new Autor("John Wayne Evald", new Date(15, 01, 1966), "Preston University"),
autors[2] = new Autor("Ildiko Philipa", new Date(07, 11, 1989), "Minesota University")
};
Chapter[] chapters = new Chapter[2];
chapters[0] = new Chapter("Introduction", section);
Book eOROOS = new Book("Design Patterns Vol 1", autors[0], chapters[0]);
}
}
Eclipse告诉我将构造函数Book（String，Autor []，Chapters []）更改为Book（String，Autor，Chapter），但我不想这样，因为我将失去agreggation和组合< / p>
