新手求助

[guojia30001]

请问：

Person human = new person();()
Vector v = new Vector();
v.add("张三");
v.add("河北");
Vector vv = new Vector();
vv.add(v);

Person human = (Person)vv.get(0);
这样做会出现ClassCastException异常，请教高手如何解决。




Person为实体类
public class Person implements Serializable {

private String Name;
private String addr;


public Person() {
}

public void setName(String Name) {
this.Name = Name;
}

public String getName() {
return Name;
}

public void setAddr(String addr) {
this.addr = addr;
}

public String getAddr() {
return addr;
}
}

v.add(new Person("张三"));
v.add(new Person("河北"));
Vector vv = new Vector();
vv.add(v);
Person human = (Person)vv.get(0);
就可以了。

楼上的,不是眼睛花了吧?你写的代码行么？

Person v = new Person();
v.setName("张三");
v.setAddr("河北");
Vector vv = new Vector();
vv.add(v);
Person human = (Person)vv.get(0);
