To answer this question, let's analyze the given code:
1. public class Threads2 implements Runnable {
2.
3. public void run() {
4. System.out.println("run.");
5. throw new RuntimeException("Problem");
6. }
7.
8. public static void main(String[] args) {
9. Thread t = new Thread(new Threads2());
10. t.start();
11. System.out.println("End of method.");
12. }
13.
}
The code defines a class Threads2
that implements the Runnable
interface. It has a run()
method that prints "run." and throws a RuntimeException
with the message "Problem". In the main()
method, a new Thread
is created with an instance of Threads2
and started. It also prints "End of method.".
Now let's go through each option to determine which ones can be the result:
Option A) A. java.lang.RuntimeException: Problem
This option is correct because the run()
method throws a RuntimeException
with the message "Problem". This exception will be caught by the JVM, and the stack trace will be printed, resulting in the output java.lang.RuntimeException: Problem
.
Option B) B. run.
This option is incorrect because it only includes the output "run.". The code also prints "End of method." after starting the thread.
Option C) C. End of method.
This option is incorrect because it only includes the output "End of method.". The code also throws a RuntimeException
in the run()
method, which will be caught by the JVM.
Option D) D. End of method. run. java.lang.RuntimeException: Problem
This option is correct because it includes all the possible outputs. The code first prints "End of method.", then starts the thread, which executes the run()
method and prints "run.". Finally, the exception is thrown and caught by the JVM, resulting in the output java.lang.RuntimeException: Problem
.
Option E) E. run. java.lang.RuntimeException: Problem End of method.
This option is correct because it includes all the possible outputs, but in a different order. The code first starts the thread, which executes the run()
method and prints "run.". Then, the exception is thrown and caught by the JVM, resulting in the output java.lang.RuntimeException: Problem
. Finally, "End of method." is printed.
Therefore, the correct answers are options D and E.
