How to write an object to an ArrayList?

Question

Java

There is a cycle

for (int i = 0; i < 10; i++) {
               	field.moveAll(); // выводит объекты в консоль, метод реализован в классе Field
       	        Thread.sleep(10);
}

How to write these objects to ArrayList?

Answer 1

In general, ArrayList has setAll / addAll () methods.
Since objects can be iterated over in for, it can be charged there as well. These methods chew on everything with the Serializable interface.
In other words:
Since field is a self-written class, then just add a method that returns objects, like this:
array.addAll(field.getObjects());

Answer 2

In general, it’s rather strange, I would like to see the whole class.
Is there a getter for objects?
If there is, use it to get it and add it all at once to the sheet using the addAll() method.
