Given the code fragments:
interface CourseFilter extends Predicate { public default boolean test (String str) {
return str.equals (“Java”);
}
}
and
List strs = Arrays.asList(“Java”, “Java EE”, “Java ME”); Predicate cf1 = s - > s.length() > 3;
Predicate cf2 = new CourseFilter() { //line n1 public boolean test (String s) {
return s.contains (“Java”);
}
};
long c = strs.stream()
.filter(cf1)
.f ilter(cf2 //line n2
.count(); System.out.println(c); What is the result?
