我对Java很陌生。我收到错误消息“构造函数Family（String，String，int）未定义”。我不确定这是什么意思。请在这里需要一些帮助。
Main.java
public class Main {
public static void main(String[] args){
Family person = new Family("CHRIS", "PEREZ", 31);
String person1 = person.getPerson();
System.out.println(person1);
}
}
家庭.java
public class Family {
String firstName;
String lastName;
int age;
int phoneNumber;
String dob;
String married;
public Family(String firstName, String lastName, int age, int phoneNumber,
String dob, String married) {
this.firstName = firstName;
this.lastName = lastName;
this.age = age;
this.phoneNumber = phoneNumber;
this.dob = dob;
this.married = married;
public String getPerson() {
return ("Hi my name is"+this.firstName+" "+ this.lastName+"."+"I am "+this.age+" years old.");
}
}
This is because your
Familyclass only has a six-argument constructor requiring all of the six fields to be provided. Your call:仅提供所需的六个中的三个。您可以覆盖构造函数，例如：
但是您应该对其他构造函数中未提供的其余字段进行处理。
您正在调用此构造函数：
但是构造函数的定义如下：
See that it has more parameters than you're passing in:
phoneNumber, dob, married. In Java you have to give values to all parameters:或者，您需要定义一个仅需要firstName，lastName和age的新构造函数。
