Question

我在将已分类的构造函数的值作为另一个类的对象传递时遇到问题。

public class Client {

   private String firstName;
   private String lastName;
   private long phoneNum;
   private String email;

   public Client (String firstName, String lastName, long phoneNum, String email) {  }
}

public class Account {

    private long accountNum;
    private double balance;
    private Client client = new Client(null, null, accountNum, null);
    private Random random = new Random();
 }

在Account类中，它是String，String，Long，String。它在帐户类中采用long值并将其放入Client参数。如何传递在Client类中指定的参数？

Answer 1

您的Account类应该是这样的：

public class Account {

    private long accountNum;
    private double balance;
    private Client client;
    private Random random = new Random();
    public Account(long accountNum){
         this.client = new Client(null, null, accountNum, null);
    }
 }

Answer 2

在“客户”类中为客户添加吸气剂和吸气剂。

在“帐户”类中设置accountNum。

然后创建一个Client实例

Client client = new Client(null, null, accountNum, null);

然后在“帐户”类中，设置客户端。

public void setClient( Client client )
{
    this.client = client;
}

传递了错误的参数。爪哇
