What will be the output of the program? class PassA { public static void main(String [] args) { PassA p = new PassA(); p.start(); }

void start() { long [] a1 = {3,4,5}; long [] a2 = fix(a1); System.out.print(a1[0] + a1[1] + a1[2] + " "); System.out.println(a2[0] + a2[1] + a2[2]); }

long [] fix(long [] a3) { a3[1] = 7; return a3; } }

  1. 12 15

  2. 15 15

  3. 3 4 5 3 7 5

  4. 3 7 5 3 7 5
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The reference variables a1 and a3 refer to the same long array object. When the [1]element is updated in the fix() method, it is updating the array referred to by a1. The reference variable a2 refers to the same array object. So Output: 3+7+5+" "3+7+5 Output: 15 15 Because Numeric values will be added
