ref an array from another class

Question

I am trying to figure out to reference an array in another class and having lots of fun. Can anyone help..? This is the code.

As I understand it the getter getName is working for a string, but I do not know how to reference an array with the getter aff_array[] get afz()

public class aff_array { String name; aff_array[] afz;

public aff_array[] getAfz() {
return afz;
}

public String getName() {
return name;
}

 public static void main (String[] args) {

    int z = 3; //total no of affirmations
    int x = 1;
    aff_array[] afz = new aff_array[z];  //dim

    while ( x < z ) {
        afz[x] = new aff_array();  // create objects for array
        x = x + 1;
    }

    afz[1].name = "i am the best";
    afz[2].name = "you are the rest";

}

This is the other class and where I want the array value to replace aff_array.class.getName() with aff_array[] getAfz() but I dont know how to do it or reference afz(1) for example (getName is working)

 public void onReceive(Context context, Intent intent)
{

    setNotification(context, aff_array.class.getName());
    WakeLocker.acquire(context);
    Toast.makeText(context,"One shot alarm received. No more toasts will be shown.", Toast.LENGTH_SHORT).show();
    WakeLocker.release();
}

what about this:

public String getAfz(int i) {
  return aff_array[i];
}

You simply need to do just :

aff_array instance = new aff_array();
// set the array inside it
setNotification(context, instance.getAfz()[0].getName());

It is required to populate the array before accessing it on the same instance instance.

It appears you want to make it static. In that case, you should declare the array as:

private static aff_array[] afz;

public static aff_array[] getAfz() {
    return afz;
}

Then you can access the array as follows:

setNotification(context, aff_array.getAfz()[1].getName());

Take note:

aff_array.class.getName() is not calling your custom getName() method. It is calling java.lang.Class.getName().

To call your custom getName() you should call aff_array.getName() (if static) or myArray.getName() where myArray is an instance of aff_array.

aff_array mainArray = new aff_array(); mainArray. afz(0).getName(); You can get in this way

The getAfz() method returns an entire array but since you need a specific entry in an array, you could either initialize the array and then reference it:

    aff_array aa = new aff_array();
    String name = aa.afz[1].getName(); // reference this in your setNotification

Or, you could create a method that returns a specific object inside an array:

    public aff_array[] getAfz(int i) {
        return add_array[1];
    }

ref an array from another class
