Give an array of type string, find each of the primes and count the number of occurrences
public void Primaryoccurrence (String ... numbers) {
list<string> L = arrays.aslist (numbers);
Map<integer, integer> r = L.stream ()
. Map (e-New Integer (e))
. Filter (E-primes.isprime (e))
. Collect (Collectors.groupingby (p->p, Collectors.summingint (p->1)));
System.out.println ("primaryoccurrence result is:" + R);
}

The Java SE 9 release is expected to be available early in 2016, enabling modular functionality for Java through the jigsaw project
