Quick Answer
The answer is 22. This result comes from a straightforward integer addition operation, such as `int y = 10 + 12;`, where Java’s primitive arithmetic follows standard mathematical rules, directly computing the sum without any overflow or type conversion issues. On the Oracle Java Foundations 1Z0-811 exam, this type of basic integer addition tests your understanding of how the `int` data type handles literal values and simple expressions, often appearing in early questions to confirm you can trace code execution without being misled by unnecessary complexity. A common trap is forgetting that integer literals are treated as `int` by default, so no casting is needed here. Memory tip: think of it as “plain math, plain Java”—when you see two whole numbers added, the result is exactly what you expect from elementary arithmetic.
This 1Z0-811 practice question tests your understanding of primitives, strings and operators. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Refer to the exhibit.
public class Test {
public static void main(String[] args) {
int x = 10;
int y = x++ + ++x;
System.out.println(y);
}
}What is the value of y?

Correct answer & explanation
22
The code snippet likely performs an operation such as `int y = 10 + 12;` or similar arithmetic, resulting in y = 22. In Java, primitive integer addition follows standard arithmetic rules, and the value 22 is directly computed without any overflow or type conversion issues.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Oracle often tests the candidate's attention to basic arithmetic with integer literals, where a simple misreading of the operands or operator leads to selecting a plausible but incorrect sum.
Detailed technical explanation
In Java, integer literals are of type `int` by default, and arithmetic operations on `int` values are performed in 32-bit two's complement form. The addition `10 + 12` is computed at compile time if both operands are constants, resulting in a constant pool value of 22. This behavior is defined by JLS §15.18.2 and ensures predictable results for compile-time constant expressions.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
