}

Correct answer: C

Given the code fragment:

Stream<List<String>> iStr= Stream.of (

Arrays.asList (“1”, “John”),

Arrays.asList (“2”, null)0;

Stream<<String> nInSt = iStr.flatMapToInt ((x) -> x.stream ());

nInSt.forEach (System.out :: print);

What is the result?

Correct answer: D

Given the code fragment:

Path file = Paths.get (“courses.txt”);

// line n1

Assume the courses.txt is accessible.

Which code fragment can be inserted at line n1 to enable the code to print the content of the courses.txt file?

List<String> fc = Files.list(file);
fc.stream().forEach (s - > System.out.println(s));
Stream<String> fc = Files.readAllLines (file);
fc.forEach (s - > System.out.println(s));
List<String> fc = readAllLines(file);
fc.stream().forEach (s - > System.out.println(s));
Stream<String> fc = Files.lines (file);
fc.forEach (s - > System.out.println(s));
