Can i remove a negative number by using ArrayList.

Question

I want the product of an array number not to be a negative number. About this problem I split it in 2 situations
1: if total of array number have an zero number and we no need to do anything. The output is zero
2: if a product of number may be positive or negative.
- if positive, we no need to remove anything just like one situation.
- if negative and total of negative number %2==0, the output is zero . In contrast, the total of negative number %2 != 0 , all we need is just remove one element

Answer 1

I'd like to understand this problem a little better.
If array is [1, 2, -3, 4]
Multiplying them together would give -24.
Would you like this number to be 24? (positive instead of negative)
Or would you like to filter the array so it becomes [1, 2, 4]
