Question

If I have a class that needs to return an array of strings of variable dimension (and that dimension could only be determined upon running some method of the class), how do I declare the dynamic array in my class’ constructor?

If the question wasn’t clear enough,

in php we could simply declare an array of strings as $my_string_array = array();
and add elements to it by $my_string_array[] = "New value";

What is the above code equivalent then in java?

You will want to look into the java.util package, specifically the ArrayList class. It has methods such as .add() .remove() .indexof() .contains() .toArray(), and more.
