Question 2

Given the code fragment:
public class FileThread implements Runnable {
 String fName;
 public FileThread(String fName) { this.fName = fName; }
 public void run () System.out.println(fName);}
 public static void main (String[] args) throws IOException,
InterruptedException {
 ExecutorService executor = Executors.newCachedThreadPool();
 Stream<Path> listOfFiles = Files.walk(Paths.get(“Java Projects”));
 listOfFiles.forEach(line -> {
 executor.execute(new FileThread(line.getFileName().toString()));
 //
line n1
 });
