静态错误：此类没有接受字符串[]的静态void main方法。

Question

我的代码编译得很好，但是当我运行它时，它给我一个错误：

`Static Error: This class does not have a static void main method accepting String[]`

这是我的密码：

class Employee{
  private String name; //name reference field
  private int idNumber; //integer variable holding employee's ID number
  private String department; //holds the name of the employees department
  private String position; //holds the name of the employee's position in the department
  //the following is the first required constructor
  //using the terms n,i,d, and p to assign values to the above fields
  public Employee(String n, int i, String d, String p){
    name=n;
    idNumber=i;
    department=d;
    position=p;
  }
  //the following is a constructor that sets the fields blank to be filled in
  public Employee(){
    name="";
    idNumber=0;
    department="";
    position="";
  }
  //writing appropriate accessor and mutator methods for all the fields
  public void setName(String n){ name=n; }
  public void setIdNumber(int i){ idNumber = i; }
  public void setDepartment(String d){ department = d; }
  public void setPosition(String p){ position = p; }
  public String getName(){ return name; }
  public int getIdNumber(){ return idNumber; }
  public String getDepartment(){ return department; }
  public String getPosition(){ return position; }
}
//new program creating employee objects
public class EmployeeInfo 
{
  public static void main(String[] args)
  {
    //create an Employee object
    Employee employee1 = new Employee("Susan Meyers", 47899, "Accounting", "Vice President");
    //test the accessor methods
    System.out.println("***employee1***");
    System.out.println("Name: " + employee1.getName());
    System.out.println("ID number: " + employee1.getIdNumber());
    System.out.println("Department: " + employee1.getDepartment());
    System.out.println("Position: " + employee1.getPosition());
    //create another Employee object
    Employee employee2 = new Employee();
    //test the mutator methods
    employee2.setName("Mark Jones");
    employee2.setIdNumber(39119);
    employee2.setDepartment("IT");
    employee2.setPosition("Programmer");
    System.out.println("\n***employee2***");
    System.out.println("Name: " + employee2.getName());
    System.out.println("ID number: " + employee2.getIdNumber());
    System.out.println("Department: " + employee2.getDepartment());
    System.out.println("Position: " + employee2.getPosition());
    //create another Employee object
    Employee employee3 = new Employee();
    //test the mutator methods
    employee2.setName("Joy Rogers");
    employee2.setIdNumber(81774);
    employee2.setDepartment("Manufacturing");
    employee2.setPosition("Engineer");
    System.out.println("\n***employee3***");
    System.out.println("Name: " + employee3.getName());
    System.out.println("ID number: " + employee3.getIdNumber());
    System.out.println("Department: " + employee3.getDepartment());
    System.out.println("Position: " + employee3.getPosition());
  }
}

我知道我需要在某个地方添加“publicstaticvoidmain（String[]args）”命令，但我不确定在哪里！谢谢你能给予的任何帮助！

Answer 1

首先，你应该编译所有的。java的文件。您可以使用命令行作为

javac *.java 

其次，您应该运行具有“main”方法的类。像

java EmployeeInfo

Answer 2

您正在创建两个不同的类雇员和雇员信息我假设您正在尝试执行雇员类，其中编译器无法找到公共静态无效主
