Which of these expressions is guaranteed to produce arithmetic overflow? (Assume `int a = Integer.MAX_VALUE; int b = 2;`)

  1. `a -- + b--`

  2. `a * b`

  3. `a - b`

  4. `a / b`

Show answer & explanation

Correct answer

`a * b`

Explanation

`a * b` = 2147483647 * 2 = 4294967294 which overflows int (max 2147483647).
