Question 73 of 509
Quick Answer
The answer is 1. The modulo operator (%) in Java returns the remainder of the division of the left operand by the right operand, so 10 divided by 3 yields a quotient of 3 with a remainder of 1, making the result of the expression 10 % 3 equal to 1. On the Oracle Java Foundations 1Z0-811 exam, this operator tests your understanding of integer arithmetic and the distinction between division (/) and remainder (%), a common trap where candidates confuse the quotient with the remainder. The exam often presents expressions like 10 % 3 in multiple-choice questions to verify you know the modulo operator finds the remainder, not the result of division. A helpful memory tip: think of the percent sign as a clock—when you go past the full hours, the remainder is what’s left over.

Correct answer & explanation
✓
1
The modulo operator (%) in Java returns the remainder of the division of the left operand by the right operand. Since 10 divided by 3 equals 3 with a remainder of 1, the expression 10 % 3 evaluates to 1.
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
Oracle often tests the distinction between the division operator (/) and the modulo operator (%), where candidates mistakenly choose the quotient (3) instead of the remainder (1).
Detailed technical explanation
How to think about this question
In Java, the modulo operator works with both integer and floating-point types, returning a result with the same sign as the dividend. For negative operands, e.g., -10 % 3 yields -1, which can be a subtle pitfall. This operator is commonly used in cyclic operations, such as determining array indices in circular buffers or checking divisibility (e.g., if (year % 4 == 0) for leap year logic).
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.
