Given:
final class Folder { //line n1
//line n2
public void open () {
System.out.print("Open");
}
}
public class Test {
public static void main (String [] args) throws Exception {
try (Folder f = new Folder()) {
f.open();
}
}
}
Which two modifications enable the code to print Open Close? (Choose two.)

Given the following array:

Which two code fragments, independently, print each element in this array?

Given the code fragment:

Which two modifications, when made independently, enable the code to print Joe:true:100.0?

Given the definition of the Country class:
public class country {
public enum Continent {ASIA, EUROPE}
String name;
Continent region;
public Country (String na, Continent reg) {
name = na, region = reg;
}
public String getName () {return name;}
public Continent getRegion () {return region;}
}
and the code fragment:
List<Country> couList = Arrays.asList (
new Country (“Japan”, Country.Continent.ASIA),
new Country (“Italy”, Country.Continent.EUROPE),
new Country (“Germany”, Country.Continent.EUROPE));
Map<Country.Continent, List<String>> regionNames = couList.stream ()
.collect(Collectors.groupingBy (Country ::getRegion,
Collectors.mapping(Country::getName, Collectors.toList()))));
System.out.println(regionNames);

Given the code fragment:
Path source = Paths.get ("/data/december/log.txt");
Path destination = Paths.get("/data");
Files.copy (source, destination);
and assuming that the file /data/december/log.txt is accessible and contains:
10-Dec-2014 - Executed successfully
What is the result?
