I have 2 different classes, Employee, PersonnelManager. I am trying to declare and instantiate an array of Employee in PersonnelManager. without using inheritance, just two completely seperate classes
public abstract class Employee {
private String firstName;
private String lastName;
private double wage;
public Employee() {
firstName = "";
lastName = "";
wage = 0.0;
}
}
public class PersonnelManager {
public Employee [] EmployeesArray;
public PersonnelManager() {
EmployeesArray= {Employee.this()}; // this is not working
}
in the Constructor of PersonnelManager How can I instantiate the array. Thank you.

You can initialize the array like below -
public PersonnelManager() {
EmployeesArray= new EmployeesArray[5];
}
or you can pass the size in constructor to make it dynamic-
public PersonnelManager(int size) {
EmployeesArray= new EmployeesArray[size];
}
Hope this will help you.

I think you're trying to instantiate an empty array of Employees in your PersonnelManager, but you're using the wrong syntax. You can do that with this:
EmployeesArray = new EmployeesArray[size];
Note that you'll have to supply a size. If you want more flexibility, then you might want to use a List instead of an array:
public class PersonnelManager {
public List<Employee> employees;
public PersonnelManager() {
employees = new ArrayList<>();
}
}

}
public class PersonnelManager {
public Employee [] EmployeesArray;
public PersonnelManager() {
EmployeesArray= new Employee[10]; // 10 is the size of an array
}
