how to get an array to reference a class

Question

I wish to try to make an array reference a class but can not think of a way to do this. I have my main class, client and another called organisation.

Im basically making a small database where the user is able to add an organisation and also edit the info in the organisation. Info including, ID#, name, address, ect

I d like to know how i can get an array to basically store new organisation class's so that when i want to add an organisation it runs a new organisation class and stores that version of the class, in the array.

Class<?> is a reflection type for a Java class. The <?> means "any class" using the generic type syntax. — John Dvorak

Is it not appropriate to just have an array of organisations: Organisation[]? — Duncan Jones

Of course, you should not be storing Classes in a database. — John Dvorak

You may be best using a List, unless you can be sure of the maximum number of organisations that can be associated with a client. The size of an array is fixed at the point it is created, which may not be appropriate for your use case.

For example:

public class Client {
  private final List<Organisation> organisations = new ArrayList<Organisation>();

  void addOrganisation() {
    // dummy/example method
    organisations.add(new Organisation("Foo", new Address("blah")));
  }
}

public class Organisation {
  private final String name;
  private final Address address;

  public Organisation(String name, Address address) {
    this.name = name;
    this.address = address;
  }
}

ArrayList<Organisation>

is the best option I think. read the documentation to get familiar with it. it's quiet handy.
