Question 2

Given the code fragment:
1Z0-809 dumps exhibit

Which code fragment, when inserted at line n1, enables the code to print /First.txt?

Path iP = new Paths (“/First.txt”);

Path iP = Paths.toPath (“/First.txt”);

Path iP = new Path (“/First.txt”);

Question 3

The data.doc, data.txt and data.xml files are accessible and contain text. Given the code fragment:
Stream paths = Stream.of (Paths. get(“data.doc”),
Paths. get(“data.txt”),
Paths. get(“data.xml”));
paths.filter(s-> s.toString().endWith(“txt”)).forEach( s -> {
try { Files.readAllLines(s)
.stream()
.f orEach(System.out::println); //line n1
} catch (IOException e) { System.out.println(“Exception”);
}
}
);

Question 4

Given:
class Sum extends RecursiveAction { //line n1 static final int THRESHOLD_SIZE = 3;
int stIndex, lstIndex; int [ ] data;
public Sum (int [ ]data, int start, int end) { this.data = data;
this stIndex = start; this. lstIndex = end;
}
protected void compute ( ) { int sum = 0;
if (lstIndex – stIndex <= THRESHOLD_SIZE) { for (int i = stIndex; i < lstIndex; i++) {
sum += data [i];
}
System.out.println(sum);
} else {
new Sum (data, stIndex + THRESHOLD_SIZE, lstIndex).fork( ); new Sum (data, stIndex,
Math.min (lstIndex, stIndex + THRESHOLD_SIZE)
).compute ();
}
}
}
and the code fragment:
ForkJoinPool fjPool = new ForkJoinPool ( ); int data [ ] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

class Car { int value = 0;
public void speed () {
value = distance /timeTravel;
System.out.println (“Velocity with new speed”+value+”kmph”);
}
}
new Car().speed();
}
}
and this code fragment: Vehicle v = new Vehicle (100); v.increSpeed(60);
