推荐回答

你的构造方法的参数对不上

class Namecard

private String name;

private String address;

private Phone data;

public Namecard(String n,String a,String str3,String str4)

name = n;

address = a;

data = new Phone(str3,str4);

class Phone

private String pany;

private String cell;

Phone(String s1, String s2)

pany = s1;cell = s2
