Set对象取值的小问题，在线等.

[zgycsmb]

现有一个类News含有 Set<Newd> newd,　如下
public class News {
private Integer id;
private String title;
private String content;
private Set<Newd> newd;
public Set<Newd> getNewd() {
return newd;
}
public void setNewd(Set<Newd> newd) {
this.newd = newd;
}
public void setId(Integer id) {
this.id=id;
}
public Integer getId() {
return this.id;
}
public void setTitle(String title) {
this.title=title;
}
public String getTitle()
{
return this.title;
}
public void setContent(String content) {
this.content=content;
}
public String getContent() {
return this.content;
}
}
另一个Newd类
public class Newd {
private int id;
private News news;
public News getNews() {
return news;
}
public void setNews(News news) {
this.news = news;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getNid() {
return nid;
}
public void setNid(int nid) {
this.nid = nid;
}
private String name;
private int nid;
}
现在测试页面中
...
....
while(it.hasNext()) {

News e = it.next();
System.out.println("ID:"+e.getNewd());
/*
此处可得到Newd对象，只是我再用e.getNewd().getId();就得不到内容，现问，我如果取到Newd对象中的属性值 呢
*/
}

大家认真帮我看下，多谢

private Set<Newd> newd; public Set<Newd> getNewd() { return newd; } public void setNewd(Set<Newd> newd) { this.newd = newd; } 现在测试页面中 ... .... while(it.hasNext()) { News e = it.next(); System.out.println("ID:"+e.getNewd()); /* 此处可得到Newd对象，只是我再用e.getNewd().getId();就得不到内容，现问，我如果取到Newd对象中的属性值 呢 */ } ---------------------------------------------------------------------------------------------- e.getNewd();返回的是一个set<Newd>的set集合啊 想要获取id 得继续遍历啊

[Runner6587]

e.getNewd() private Set<Newd> newd; public Set<Newd> getNewd() { return newd; } 这样只是返回的set数组啊！要e.getNewd().get(Index)才得到Newd对象接着再getId()

[姜小白-]

public Set<Newd> getNewd() { return newd; } getNewd 获取到的是 Set<Newd> 拿到后，需要再从Set中遍历Newd 对象 Iterator it = newd.iterator(); while (it.hasNext()) { Newd newD = it.Next(); newD.getId() }
