Given the following code fragment: class Finder extends SimpleFileVisitor<Path> { private final PathMatcher matcher; private static int numMatches = 0;
Finder() {
matcher = FileSystems.getDefault().getPathMatcher("glob:*java");
}
void find(Path file) {
Path Name = file.getFileName();
if (name != null && matcher.matches(name)) {
numMatches++;
}
}
void report()
{
System.out.println("Matched: " + numMatches);
}
@Override
public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) {
find(file);
return CONTINUE;
}
}
public class Visitor {
public static void main(String[] args) throws IOException {
Finder finder = new Finder();
Files.walkFileTree(Paths.get("d:\\Project"), finder);
finder.report();
}
}
What is the result?

Given the incomplete pseudo-code for a fork/join framework applications:
submit (Data) { if (Data.size < SMALL_ENOUGH) { _________(Data); // line X } else { List<Data> x = _________________(Data); // line Y for(Data d: x ______________(d); // line Z } }
And give the missing methods:
Process, submit, and splitInHalf
Which three insertions properly complete the pseudo-code?

Given the following code fragment:
public static void getInfo() {
//insert code here
List fontCatalog = new ArrayList();
fontCatalog.add("Algerian");

category.put("firstCategory",fontCatalog);
List entrySet = new ArrayList(category.entrySet());
Iterator it = entrySet.iterator();
while(it.hasNext()) {
System.out.println(it.next));
}
}
Which two code fragments, when inserted independently at line **, enable the code to compile?
