(java)

hello!

as you see i have the answer to this, but still having problem undrestanding it.

the "." after p, to me seems like p is calling intArray method. but it shouldnt be the case because instead of () there is a [], would you please clarify?

12. Please write the output for the following program. public class TestJavaMain { final int[] p = (4,5,6); // intArray public static void main(String[] args) { System.out.printin(p.intArray (op -+ p.intArray(1)+" + P.intArray[2]); ) (a) it has a compile error. (b) it displays "456" (c) it displays "156". (d) it throws an exception. Answer: c. (the final variable of object cannot change its reference to another object, but you still can modify the value of the object.)
