element of the array from another class

[Nattakan Lukkanapinit]

Create a class Agent that contains:


String name - the Agent's name
Client[] my_Clients - an array of Client references. Allocate an array of some fixed size, MAX_CLIENTS, but don't instantiate individual Clients ... we allow this array to point to the caller's Client objects.
int num_Clients - the current number of Clients this Agent has.
MAX_CLIENTS, MIN_NAME_LEN, MAX_NAME_LEN - some static finals to control the values passed into mutators.
Give the Agent class the minimal constructors plus these methods:

AddClient(Client client) - puts client into the Agent's list.
RemoveClient(Client client) - removes client by squeezing him out of the list.
ShowClientsShort() - Displays a list of all this Agent's Clients' names (only names).
ShowClientsLong() - Displays a list of all the Clients, using the Client display method.
double GetIncome() - Returns the dollar amount collectable from all Clients so far this year (based on the tally of the Client member data, percent_cut, and income_this_year.
Create a main program that instantiates a number of Actors and Writers, displays a few of their data to the screen, individually (not all). Next, instantiate one Agent, and place some of the Actors and Writers into the Agent's list. Print out the Agent's Clients' names demonstrating both ShowClients---() methods, and show how much money the Agent is going to get this year.

I tried to add Cli1 in the main just to test but it doesn't work.
the output is "Client@6bdd46f7".
My question is:
How to store "Cli1" in to the array

import java.util.List;  
import java.util.ArrayList;

   public static void main(String[] args)

     Cli2 = new Client();
     
     Cli1.display();
     Cli2.display();
     
     Writer Wri1;
     Wri1 = new Writer("Hong",100000000,.14,Writer.CEP,"GOV");
     
     Wri1.display();

     Act1.display();

     AGT1 = new Agent();
     
     AGT1.AddClient(Cli2);

     System.out.println(my_Clients[0]);

Hong, Your problem had me scratching my head for you are adding a valid Client object to the array, and placing this object in a System.out.println(...) method should automatically call Client's toString method, a method which on brief inspection looks valid. But then I did a debugging trick that might help you in the future: simplify the problem until it stands out. I create a small program that had just the essense of your program:

public class ClientTest2 {
  public static void main(String[] args) {
    Client2 Cli1, Cli2;
    Cli1 = new Client2("Hong", 100000000, .14);
    Cli2 = new Client2();

    Cli1.display();
    Cli2.display();

    Client2[] my_Clients = new Client2[99];
    my_Clients[0] = Cli1;

    System.out.println(my_Clients[0]);

    System.out.println(my_Clients[0]);
  }
}

class Client2 {
  private String name;
  private long income_this_year;
  private double percent_cut;

  static final int MIN_INCOME_VAL = 0;
  static final int MAX_INCOME_VAL = 1000000000;
  static final int MIN_NAME_LEN = 0;
  static final int MAX_NAME_LEN = 50;

  public Client2() {
    SetName(" (undefined) ");
    Set_income_this_year(0);
    Set_percent_cut(.10);
  }

  public Client2(String name, long income_this_year, double percent_cut) {
    SetName(name);
    Set_income_this_year(income_this_year);
    Set_percent_cut(percent_cut);
  }

  void display() {
    System.out.println(ToString());
  }

  public String ToString() {
    String result;
    result = GetName() + "\n" + +Get_income_this_year() + "\n" + +Get_percent_cut();
    return result;
  }

  public String GetName() {
    return name;
  }

  public long Get_income_this_year() {
    return income_this_year;
  }

  public double Get_percent_cut() {
    return percent_cut;
  }

  public boolean SetName(String name) {
    if (name.length() > MIN_NAME_LEN && name.length() < MAX_NAME_LEN) {
      this.name = name;
      return true;
    }
    return false;
  }

  public boolean Set_income_this_year(long income_this_year) {
    if (income_this_year > MIN_INCOME_VAL && income_this_year < MAX_INCOME_VAL) {
      this.income_this_year = income_this_year;
      return true;
    }
    return false;
  }

  public boolean Set_percent_cut(double percent_cut) {
    if (percent_cut > 0 && percent_cut < 1) {
      this.percent_cut = percent_cut;
      return true;
    }
    return false;
  }

}

and still had the same problem. But this code is much smaller and much easier to play with, inspect and dissect. And on doing this, I found that your toString method in fact isn't kosher as it begins with a capital letter -- "ToString()" instead of "toString()". If you try to use the @Override annotation you'll get a compile error, and if you fix this problem, you'll see that your solution does in fact work -- as long as toString() is working correctly.

Sorry about the rambling, and please post back if this doesn't make sense.
