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