Java 8 Test

Question #1 of 3

Consider the following code:

System.out.println("Print all elements");
List list = Arrays.asList(5,6,7,8,9);
for(Integer n: list) 
{
    System.out.println(n);
}

How can we simplify the above code using the lambda expression?

    • System.out.println("Print all itens"); List<Integer> list = Arrays->asList(5,6,7,8,9); list.forEach(n -> System.out.println(n));

    • System.out.println("Print all itens"); List<Integer> list = Arrays.asList(5,6,7,8,9); list.forEach(n -> System.out.println(n));

    • System.out.println("Print all itens"); List<Integer> list = Arrays.asList(5,6,7,8,9); list.foreach->(n -> System.out.println(n));

    • System.out.println("Print all itens"); List<Integer> list = Arrays.asList(5,6,7,8,9); list.foreach(n -> System.out.println(n));

Question #2 of 3

Consider the following code:

Runnable r = new Runnable() 
{
    public void run() 
    {
        System.out.print("Internal class with thread!!!!!!");
    }
};
new Thread(r).start();

How can we simplify the above code using the lambda expression?

    • Runnable r = ()::System.out.print->("Thread with lambda!"); new Thread(r).start();

    • Runnable r = () -> System.out.print("Thread with lambda!")->new Thread(r).start();

    • Runnable r = () -> System.out.print("Thread with lambda!"); r -> new Thread(r).start();

    • Runnable r = () -> System.out.print("Thread with lambda!"); new Thread(r).start();

Question #3 of 3

Consider the following code:
billOutOfDate.forEach({ sender.send(b.getMail(), b.resume()); b.setNotification(true);});

The above code contains an error. How can we solve the problem?

    • billOutOfDate.forEach(b -> { sender.send(b.getMail(), b.resume());
      b.setNotification(true);});

    • billOutOfDate.forEach(b::{ sender.send(b.getMail(), b.resume());
      b.setNotification(true);});

    • billOutOfDate.forEach(Bill b{ sender.send(b.getMail(), b.resume());
      b.setNotification(true);});

    • billOutOfDate.forEach(Bill b::{ sender.send(b.getMail(), b.resume());
      b.setNotification(true);});
