Given the code fragments:

interface CourseFilter extends Predicate {

public default boolean test (String str) {

return str.contains ("Java");

}

}

and

List strs = Arrays.asList("Java", "Java EE", "Embedded Java");

Predicate cf1 = s - > s.length() > 3;

Predicate cf2 = new CourseFilter() { //line n1

public boolean test (String s) {

return s.startsWith ("Java");

}

};

long c = strs.stream()

.filter(cf1)

.filter(cf2 //line n2

.count();

System.out.println(c);

What is the result?
