Given the code fragments:
class ThreadRunner implements Runnable {
public void run () { System.out.print (''Runnable'') ; }
}
class ThreadCaller implements Callable {
Public String call () throws Exception {return ''Callable''; )
}
and
ExecutorService es = Executors.newCachedThreadPool ();
Runnable r1 = new ThreadRunner ();
Callable c1 = new ThreadCaller ();
// line n1
es.shutdown();
Which code fragment can be inserted at line n1 to start r1 and c1 threads?
Given the code fragment:
List
DoubleFunction funD = d --> d + 100.0;
doubles.stream (). forEach (funD); // line n1
doubles.stream(). forEach(e --> System.out.println(e)); // line n2
What is the result?
Given:
public class Product {
int id; int price;
public Product (int id, int price) {
this.id = id;
this.price = price;
}
Public String toString () { return id + '':'' + price;)
}
and the code fragment:
List
new Product (2, 30),
new Product (3, 20));
Product p = products.stream().reduce(new Product (4, 0), (p1, p2) -> {
p1.price+=p2.price;
return new Product (p1.id, p1.price);});
products.add(p);
products.stream().parallel()
.reduce((p1, p2) - > p1.price > p2.price ? p1 : p2)
.ifPresent(System.out: :println);
What is the result?
