Question

When evaluating what triggers an overflow error, we must consider the limits of integer representation in most programming languages.
Option 1: 'we add on to Integer.MIN_VALUE' — Overflow here would occur if you wrap around from the minimum value when you exceed the negative bound, but simply adding to the minimum value does not inherently cause overflow unless you pass below it. This statement mischaracterizes the common overflow trigger.
Option 2: 'we subtract 5000 from Integer.MAX_VALUE' — Subtracting a positive amount from the maximum value typically reduces the value rather than exceeding it. This would not cause an overflow; it would move toward the lower end of the range, possibly underflowing only in the unlikely event of extreme underflow, which is not the described scenario.
Option 3: 'we add 5000 to Integer.MIN_VALUE' — Adding a positive amount to the minimum value increases the number, but as long as the result stays within the valid range, no overflow occurs. This could be fine until the sum crosses into the permitted range; however, starting at MIN_VALUE and adding 5000 would still be far from causing overflow unless you add enough, and the stated operation itself is not the classic overflow trigger.
Option 4: 'we add on to Integer.MAX_VALUE' — This is the classic overflow scenario: pushing beyond the maximum representable integer value by adding to it causes the value to wrap around or overflow, depending on the language and arithmetic rules. This matches the standard definition of integer overflow.
Thus, among the provided options, the statement that accurately describes an overflow error is the one about adding to Integer.MAX_VALUE. However, the wording in the other options is intentionally misleading to test understanding of boundary conditions and arithmetic behavior. In common contexts, overflow arises when an operation yields a result outside the allowable range, which this option directly encapsulates.
