The returned ArrayList$>$ should have three sub lists.

The first sub list should contain the zero integers from the input list.

The second sub list should contain the negative integers from the input list.

The third sub list should contain the positive integers from the input list.

The entries in each sub list should be in the same order that they were in in the input list,

Any one of the three sub lists could be an empty list $($even all three of them$).$

Use an enhanced for$-$loop whenever possible.
