Given:
var fruits = List.of("apple", "orange", "banana", "lemon");
You want to examine the first element that contains the character n. Which statement will accomplish this?

• A.Optional<String> result = fruits.stream().anyMatch(f -> f.contains("n"));
• B.Optional<String> result = fruits.stream().filter(f -> f.contains ("n")).findFirst ();
• C.String result = fruits.stream().filter(f -> f.contains("n")).findAny();
• D.fruits.stream().filter(f -> f.contains("n")).forEachOrdered(System.out::print);

Given:

Which is true?

• B.System.in cannot reassign the other stream.
• C.System.out is an instance of java.io.OutputStream by default.
• D.System.out is the standard output stream. The stream is open only when System.out is called.

Given the code fragment:
Path currentFile = Paths.get("/scratch/exam/temp.txt");
Path outputFile = Paths get("/scratch/exam/new.txt");
Path directory = Paths.get("/scratch/");
Files.copy(currentFile, outputFile);
Files.copy(outputFile, directory);
Files.delete (outputFile);
The /scratch/exam/temp.txt file exists. The /scratch/exam/new.txt and /scratch/new.txt files do not exist.
What is the result?
