Question 88 of 509
Quick Answer
The answer is -2147483648. This occurs because when an int variable holding Integer.MAX_VALUE (2147483647) is incremented, integer overflow wrapping happens in Java’s 32-bit two’s complement representation, causing the value to wrap around to the smallest possible int, which is Integer.MIN_VALUE (-2147483648). On the Oracle Java Foundations 1Z0-811 exam, this concept tests your understanding of primitive data type limits and overflow behavior—a common trap is assuming the program will throw an exception or that the value will simply stop increasing. Instead, Java silently wraps the value, making this a frequent multiple-choice pitfall. Remember the “clock face” tip: just as a clock wraps from 12 to 1, an int wraps from its maximum to its minimum, so MAX_VALUE + 1 always equals MIN_VALUE.

Correct answer & explanation
✓
-2147483648
When x is Integer.MAX_VALUE (2147483647) and incremented, integer overflow occurs because Java int uses 32-bit two's complement representation. The value wraps around to the minimum int value, which is -2147483648, making D correct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often expect an exception or a reset to zero, but Java silently handles integer overflow by wrapping around to the minimum value due to two's complement arithmetic.
Detailed technical explanation
How to think about this question
Java's int type is a 32-bit signed two's complement integer. When Integer.MAX_VALUE (0x7FFFFFFF) is incremented, the binary representation becomes 0x80000000, which is -2147483648. This behavior is defined by the Java Language Specification (§4.2.2) and is not an error; it's a common pitfall in arithmetic operations, especially in loop counters or hash calculations.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-811 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
