Question

Question 10 (3 points) Which of the following statement is not true? There is a recursive sum method as shown below. When sum (19) is called, summation of all odd numbers less than 19 will be calculated and returned public int sum(int x){ if (x == 0) return 0: else return sum(x-2) + x; The following code segment will throw a testException. This exception has been handled in the way that do nothing but to continue when this exception happens. The program will continue int salary =1000; if(salary <5000) throw testException; }catch testException e) } Assume code in a try block may throw both NullPointerException and ArithmeticException, by designing the catch block as catch(Exception e) {...} would allow both type of exceptions be handled in the same catch block. That is, no matter a NullPointerException or an ArithmeticException occurs, the catch block is able to catch the exception The following defines a new Exception called ANewException public class ANewException extends NullPointerException public NewException(String message) { super(message); } Question 11 (3 points) What does the following recursive method determine? public boolean question16(int[]a, int[] b. intj) if ( == a.length) return false; else if (j = = b.length) return true: else return question16(2, b.j=1); { السره retums true if b contains less elements than a, false otherwise retums true if b contains more elements than a, false otherwise retums true if a and b are equal in size, false otherwise returns true if a's element value is larger than b, false otherwise

Answer 1

Question 10:

First option is the correct answer.

The program will run an infinite loop as the only stopping condition provided in the code is:

if (x == 0)

But the value of x will never be zero as it will return all the odd numbers less than 19 and in each iteration the sum is decreased by two. So, when it will be 1 in the next iteration it will be -1. So, no stopping condition will be satisfied.

Second option is incorrect as it is true.

Third option is incorrect as it is true.

Fourth option is incorrect as it is true.
