結果は何ですか？
정답: A
コードの断片を考えると：
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?
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?
정답: B
Given:
public final class IceCream {
public void prepare() {}
}
public class Cake {
public final void bake(int min, int temp) {}
public void mix() {}
}
public class Shop {
private Cake c = new Cake ();
private final double discount = 0.25;
public void makeReady () { c.bake(10, 120); }
}
public class Bread extends Cake {
public void bake(int minutes, int temperature) {}
public void addToppings() {}
}
どちらの説明が正しいですか？

정답: D
Given:
class FuelNotAvailException extends Exception { }
class Vehicle {
void ride() throws FuelNotAvailException {//line n1
System.out.println("Happy Journey!");
}
}
class SolarVehicle extends Vehicle {
public void ride () throws Exception {//line n2
super ride ();
}
}
and the code fragment:
public static void main (String[] args) throws FuelNotAvailException,
Exception {
Vehicle v = new SolarVehicle ();
v.ride();
}
Which modification enables the code fragment to print Happy Journey!?
class FuelNotAvailException extends Exception { }
class Vehicle {
void ride() throws FuelNotAvailException {//line n1
System.out.println("Happy Journey!");
}
}
class SolarVehicle extends Vehicle {
public void ride () throws Exception {//line n2
super ride ();
}
}
and the code fragment:
public static void main (String[] args) throws FuelNotAvailException,
Exception {
Vehicle v = new SolarVehicle ();
v.ride();
}
Which modification enables the code fragment to print Happy Journey!?
정답: B
コードの断片を考えると：
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
});
executor.shutdown();
executor.awaitTermination(5, TimeUnit.DAYS);//
line n2
}
}
The Java Projects directory exists and contains a list of files.
What is the result?

String fName;
public FileThread(String fName) { this.fName = fName; }
public void run () System.out.println(fName);}

コードの断片を考えると：
ZonedDateTime depart = ZonedDateTime.of(2015, 1, 15, 1, 0, 0, 0, ZoneID.of("UTC-7")); ZonedDateTime arrive = ZonedDateTime.of(2015, 1, 15, 9, 0, 0, 0, ZoneID.of("UTC-5")); long hrs = ChronoUnit.HOURS.between(depart, arrive); //line n1 System.out.println("Travel time is" + hrs + "hours"); 結果は何ですか？
