Increase the length of object array

[GoToLoop]

You need to (cast) the array to your type like this:

Pasting this modified expand() to a sketch, there’s no more need to use (cast) over the returned array:

P.S.: The overridden expand() method needs: import java.util.Arrays; in order to compile.

Alternatively you can prefix java.util. to Arrays.copyOf(list, newSize):
return java.util.Arrays.copyOf(list, newSize);
