Java-错误 : Actual and formal argument lists differ in length

Question

运行代码时会产生此错误

Employee cannot be applied to given types;  
  required: no arguments  
  found: java.lang.String,double,int  
  reason: actual and formal argument lists differ in length

主类:

public class Salary {
    public static void main(String[] args) {
        Employee worker = new Employee("harry",5.5,45);
        System.out.println(worker.getEmployeeName());
        System.out.println("Your Gross Salary is"+ worker.getGrossSalary());
        System.out.println("after tax is"+ worker.getNetSalary());

    }

}

Employee类的构造函数:

public void Employee(String n , double pr, int h){
    name = n;
    payRate = pr;
    hours = h; 
}

Answer 1

构造函数不能也不应该有返回类型。

public void Employee(String n, double pr, int h){ // this is considered a method that belongs to that particular object
    name = n;
    payRate = pr;
    hours = h; 
}

更改为:

public Employee(String n , double pr, int h){ // this is considered a constructor, invoked when you're making an object of this type
    name = n;
    payRate = pr;
    hours = h; 
}
