Here is the algorithm for counting matches from the the "Counting Matches" subsection of the "Common Loop Algorithms" section:

int spaces $=0$;

for $($int i $=0$; i $<$ str$.$length$()$; i$++)$

$\{$

char ch $=$ str$.$charAt$($i$)$;

if $($ch $==\text{'}\text{'})\{$ spaces$++$; $\}$

$\}$

Adapt this algorithm to print the number of positive and negative values in a given array. Zero is neither positive nor negative.
