我正在创建一个简单的GUI窗口来管理教师列表， 我遇到的错误是：
--------------------Configuration: FacultyListFrame1 - JDK version 1.7.0_02 <Default> - <Default>--------------------
C:\Users\lm_b116\Documents\JCreator Pro\MyProjects\Myfaculty\FacultyListFrame1.java:175: error: no suitable constructor found for Faculty(String,Name,MyDate,boolean)

这是Faculty的代码
public class Faculty extends Person{
private double salary;
private boolean fullTime;
public Faculty (int ssn, Name name, MyDate birth)
{
super(ssn, name, birth);
}
public Faculty (int ssn, Name name, MyDate birth, double salary, boolean f)
{
super(ssn, name, birth);
this.salary = salary;
fullTime = f;
}
public void setSalary (double salary)
{
this.salary = salary;
}
public double getSalary()
{
return salary;
}
public void setFullTime (boolean f)
{
fullTime = f;
}
public boolean getFullTime()
{
return fullTime;
}
public String toString()
{
String faculty = new String ("");
if (fullTime == false)
faculty = super.toString() + "\t" + salary + "\t part time ";
else
faculty = super.toString() + "\t" + salary + "\t full time ";
return faculty;
}
}
答案 0 :(得分：1)
您正在尝试传递4个参数，但根据错误消息，Faculty的构造函数需要3个或5个参数。
要么不将selectedStatus变量传递给构造函数，要匹配Faculty(int,Name,MyDate)，要么在double之前包含selectedStatus值以匹配Faculty(int,Name,MyDate,double,boolean)。
另一种选择：创建4参数构造函数以匹配您尝试调用的内容：Faculty(int,Name,MyDate,boolean)。
