    But it’s illogical. For example, why it still takes all cases when I=5? It should consider order of cases, shouldn’t it? If we hit 5, we should not hit 1 and possibly should hit 2. I can’t see a reason.

    • Hi.. let me try to explain it..

      In this quiz, we have a switch inside a for-each loop. This is allowed in java.
      Since we have 4 elements in nums, it the switch will be evaluated 4 times.
      For first time, i is checked for 1 and match is found in case 1. So, x =1.But since there is no break statement, it will fall through and i will be 4 when it comes out of switch.
      Similarly, the outputs on next iterations are 6, 12 and 27. 27 is the value of x after final loop.
      Let us know if you still have confusions.

      Thanks for visiting.
