Question

I am developing an Android project in which I need to return multiple List objects from a method. Is this possible?

For example, I have created two different List objects ….

List<String> tid_list=new ArrayList<String>();
List<String> tno_list=new ArrayList<String>();

and I want to return them from a method. How can I achieve this?

Answer 1

A function can, by definition, only return one value, so you’re left with a couple of options.

• You can make a new class that has tid_list and tno_list as properties of it
• You can make your method return an ArrayList that contains the two ArrayLists
• If tno_list and tid_list are properties of the class and the function is a method of the same class, you can edit them inside the method and completely skip the parameters/return value route.
