I got a structure of employees (similar to a file structure on a computer).

The "root" employees are stored in a arrayList (the employees with a depth of 0).

1. class Location{
    
     String name;
     ArrayList<Employee> employees = new ArrayList<Employee>();
    
     Location(String name){
       this.name = name;
     }
    
   }

The class employee has a array to store employees aswell, for the deeper nested.
(code here is stripped to minium jus to show basic structure).

1. class Employee{
     
      Employee[] children = new Employee[0];
    
     Employee(){
     };
2. 
   
3.   void printList(){
       printList(0);
     };
    
     // - - - - -
    
     void printList(int depth){
       // Print spaces for each level of depth
       for (int i = 0; i < depth; i++){
         print("\t");
       }
       //println(email);
      //println(number);
      println("•");
      
       // Now handle the children, if any.
       for(Employee employee : children){
         employee.printList(depth + 1); 
       }
     };
   
4. 
   }

I can easilly print the total structure by calling this from main:

1.   for(Location location : locations){
       println("\n"+location.name+"\n");
         for(Employee employee : location.employees){
           employee.printList();
         }
     }

However, i want to draw a data circle of the employee tree.
For this i would like to go threw every employee just from the main tab.
But i have no idea how to cyle threw each employee from here,
something like this could work:

1. for(Location location : locations){
     for(Employee employee : location.employees){
       drawEmployee(employee);
       for(Employee childEmp : employee.children){
         drawEmployee(childEmp);
         for(Employee childEmp : employee.children){
           drawEmployee(childEmp);
           for(Employee childEmp : employee.children){
               drawEmployee(childEmp);
               for(Employee childEmp : employee.children){
                 drawEmployee(childEmp);
             }
           }
         }
       }
     }
   }
   

But it doesn't make sense to do it like that, cause if something is nested really deep then that's really ****ed.
Or is the best way to have the draw function inside the Employee class itself?
