Question

我需要传递一个未在方法中定义的1d数组。

我需要创建一个测试类，然后自己创建数组。

我只是不确定语法。

示例，这是我的公司类：

public class Company
{
String name;
String address;
Employee employeeList[] = new Employee[3];

public Company (String name, String address ,
                     Employee employeeList, String jobTitle )
{
    this.name = name;
    this.address = address;
}
public void printDetails()
    {
        for(int i = 0; i>employeeList.length;i++)
        {
            System.out.println(" The companys name is " + name);
            System.out.println(" The Companys Address is "+ address);
            System.out.println("The List of employees are " + employeeList[i].name);
            System.out.println("The Titles of These Employees are " + employeeList[i].jobTitle);
        }
    }
}

但我的测试类是问题所在。

我从哪里开始？我是否应该将arrays(employees)加入其中？

public class TestCompany
{
public static void main(String[] args)

{                                                                        employees?
Company hungryBear = new Company("hungryBear ", "Those weird apartments ",//////   );
}
}

Answer 1

public Company (String name, String address ,
                     Employee employeeList, String jobTitle )

应该是：

public Company (String name, String address ,
                     Employee []employeeList, String jobTitle )

现在，您没有将数组传递给您的方法，而是传递实例。您需要告诉Java您正在传递数组。

编辑了员工班的新知识......

此外，在传递数组之前，您需要在main函数中构建数组。像这样：

public static void main(String[] args){                                                                        
    Employee [] employeeList = {
        new Employee("Samuel T. Anders", "Player, Caprica Buccaneers"),
        new Employee("William Adama", "Commander, Battlestar Galactica")
    };

    Company hungryBear = new Company("hungryBear ", "Those weird apartments ", employeeList);
}

不确定这会回答你的问题，但也许这会帮助你传递一点点数组的语法。

另一种编辑，另一种初始化数组的方法：

Empolyee [] employeeList = new Employee[2];
employeeList[0] = new Employee("Samuel T. Anders", "Player, Caprica Buccaneers");
employeeList[1] = new Employee("William Adama", "Commander, Battlestar Galactica");

Answer 2

Empolyee [] employeeList = new Employee[2];


for(int i=0;i<2;i++){
  Scanner input = new Scanner(System.in);

  employeeList[i] = input.next();
}

将数组传递给testclass构造函数
