package example;

import java.util.Arrays;
import java.util.stream.IntStream;

public class FilterTest {

   public static void main(String[] args) {
     int[] test = new int[]{-2,-1,0,1,2};
     filter(test).forEach(p -> System.out.println(p));

   }
   static IntStream filter(int[] t) {
     IntStream stream = Arrays.stream(t);
     return stream.filter(o->o<-o);
   }

}
