java - 方法中的继承程序错误

Question

我在实现我的子类 Customer 时遇到问题，我收到预期错误 58:“number="”;"我试图让客户类继承我的 Person 类中的方法。

到目前为止我的程序:

   import java.util.Scanner;

   public class Person
   {
   private String name;
   private String address;
   private String number;

   public Person() //No Argument constructor//
   {
    name= "";
    address= "";
    number= "" ;
   }

   public Person(String num, String nam, String add) //Explicit value constructor//
    {
   number= num;
   name= nam;
   address= add;
   }
   public String getName() //Accessor method//
    {
    return name;
    }

   public void setName(String name )//Mutator method//
   {

   this.name= name;
   }

   public String getAddress()
   {
   return address;
   }
    public void setAddress(String address)
    {
    this.address= address;
     }
    public String getTelephoneNumber()
    {
    return number;
    }
    public void setNumber(String number)
    {
    this.number= number;
    }

    public String toString ()
    {
    return name + "\n" + address + "\n" + number;
    }}

    public class Customer extends Person 
    {

    number="";

    public Customer(String num, String nam, String add) 
     {
     super (number);

     }

     public void addChoice(String number, boolean correct)
     {
      choice.add(choice);
      if (correct)
     {
      setAnswer(choiceString);
      }
       }
      public void display()
       {
      super.display();
       }
       }

这是什么很简单。您不小心在 getName 声明后放置了右大括号 } 而不是左大括号 {。真的很容易修复。
