java - 传递了错误的参数。 java

Question

我在将参数化构造函数的值作为另一个类中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) {  }
}

<小时/>

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。它获取帐户类中的 long 值并将其放入 Client 参数中。如何传递我在 Client 类中指定的参数？

Answer 1

您的 Account 类应如下所示:

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);
    }
 }
