java - Getter、Setter、对象 Java

Question

我不确定我的代码有什么问题。我的代码 Person类如下所示。

我不知道从哪里开始我的 main 方法，对于像这样实例化的 Person 类中的对象:

newPerson = new Person( 
                   "Richard Pelletier", 
                   "1313 Park Blvd",
                   "San Diego, CA 92101",
                   "(619) 388-3113" );

人:

public class Person 
{  
        private String name;
        private String address;
        private String cityStateZip;
        private String phone;

    public Person(){}

    public Person( String name,
                        String address,
                        String phone )                          
    {
        this.name = name;
        this.address = address;
        this.phone = phone;
    }

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

    public void setAddress( String address )
    {
        this.address = address;
    }

    public void setPhone( String phone )
    {
        this.phone = phone;
    }

    public String getName()
    {
        return name;
    }

    public String getAdress()
    {
        return address;
    }

    public String getPhone()
    {
        return phone;
    }

    public String toString()
    {

     return ("" + this.name + "" + this.address + "" + this.phone);

    }
}

我假设您有编译器错误。您的构造函数仅接受三个 String 参数，而您正尝试传递四个参数。尝试添加以下构造函数(或替换现有的构造函数):

public Person( String name,
               String address,
               String cityStateZip,
               String phone )                          
{
    this.name = name;
    this.address = address;
    this.cityStateZip = cityStateZip;
    this.phone = phone;
}
