Cannot resolve symbol "add" while adding class object to an ArrayList

I am working on a class for an Address Book Application on Java called "AddressBook.java", which I have written the following code:

package com.company;
import java.util.ArrayList;

class AddressBook {
    ArrayList<AddressEntry> addressEntryList = new ArrayList<AddressEntry>();
    AddressEntry test = new AddressEntry("john", "doe", "yes", "no", "maybe", 1, "I guess", "ok");
    
    addressEntryList.add(test);
}

Since I was just testing the test object, I had to give random values for the variables from my AddressEntry class and it seemed to work well. However, when I ran it in IntelliJ, I received the error

Cannot resolve symbol 'add'

This made the adding method not working.

You can only use your ArrayList object methods (for example .add, .remove etc) inside other methods, this can also be the main method (obviously)

You need to put it inside the main method.

Like this:

package com.company;
import java.util.ArrayList;

class AddressBook {
    public static void main(String[] args){
        ArrayList<AddressEntry> addressEntryList = new ArrayList<AddressEntry>();
        AddressEntry test = new AddressEntry("john", "doe", "yes", "no", "maybe", 1, "I guess", "ok");
        addressEntryList.add(test);
    }
}

Java cannot resolve method calls if the method call does not call from any method.
