I know if it was a primitive type array, such as an int, it would be 0s, but as an object, such as a String or a custom-made class, is it still 0? NULL? Or what?

It’s always the default value for the element type –
nullfor any class types, 0 for numeric types,'\0'forcharandfalseforboolean. (NULLdoesn’t exist in Java, and 0 is a meaningless value for a reference. It may be the physical representation in memory, but it’s not a reference value in itself.)See section 15.10.1 of the JLS for how array creation works, and section 4.12.5 for more explicit detail on the default values of different types.
