hi,

One of the question from a mock test of examguide online is ..........

class C {

public static void main (String[] a1) {

System.out.print(a1[1] + a1[2] + a1[3]);

}}

What is the result of attempting to compile and run the program?


java command A B C

1.Prints: ABC

2.Prints BC and Runtime Exception

3.Prints: BCD

4.Runtime Exception

5.None of the above


The given answer for this Answer 2(array index outof bounds exception only till a1[2] is allowed.)
but I think the answer for this 4.runtime exception. when i tried to execute array out of bound exception has arrivied, with no output as BC. So how can one justify the answer to be no.2? please explain.

Hi Usha,

The answer given is wrong. It should be 4. You may want to inform the author of examguide about this error.
